One possible reason here could be the fact that since the person is being watched while doing this exercise, they might tend to breather deeper than they normally do. Secondly, it may also be because the person is trying to make up for the spit filter and flow meter by breathing harder/sharper than they normally would.
Which of the following techniques involves hybridizing a cDNA sample to a chip containing thousands of single-stranded DNA sequences, allowing one to study the expression of thousands of genes simultaneously?
A) PCR
B) Southern blot
C) FISH
D) Agarose gel electrophoresis
E) DNA microarray
Answer: Option E.
DNA micro array.
Explanation:
DNA microarray is a technique that involves hybridizing cDNA into a chip that contains thousands of single stranded DNA sequences. This technique enables one to study expression of thousands of genes at the same time.looks for extra (duplicated) or missing (deleted) chromosomal segments, sometimes called copy number variants (CNVs).
DNA microarrays are microscope slides which are printed with thousands of tiny spots in specific different positions, and each of the spots contain a known DNA sequence or gene.
primary use of DNA microarrays is transcriptional profiling.
The basic principle behind the DNA microarray is “ nucleic acid hybridization.

Answer:
1.fungi, 2.fungi 3.monera 4.fungi 5. protista 6. animalia
Explanation:
since, yeast is a fungus , penicilium and mushroom (agaricus) also fall under this catergory due to the presence of mysceliom and hyphae.
rizobium is a bacteria so falls under the kingdom monera
amoeba has locamotory organs hence is a part of the protista kingdom
while , fish is an animal and thus belong to animalia
felice has a scar on her arm that happened when she broke a glass at the age of 3. at the age of 8, she asked her mom why she has a scar, and her mom responded that she was bitten by the neighbor's dog. since then, whenever she is asked about the scar, she has a distinct memory of what happened on the day the dog bit her (even though this never happened). this illustrates: the equipotentiality hypothesis the encoding specificity principle the misinformation effect levels of processing theory
Answer:
the misinformation effect
Explanation:
In psychology, misinformation effect occurs when false memories are formed as a result of the misleading information that was provided after the original event has taken place. This effect was studied by a psychologist named Elizabeth Loftus.
Elizabeth Loftus in her series of experiments discovered that false memories about an event can be induced by suggesting or giving wrong information about it. Hence, the involved persons remember a wrong information about the experienced event based on what they were led to remember via wrong information.
This is the case Felice, who was fed with a wrong information about the scar on her arm. This information make her have a false memory of the event i.e dog bite instead of a broken glass
A sequence of DNA ( 3' CCTCCGATGA 5' ) is used as a TEMPLATE strand for dideoxy sequencing. The products are made and the products are run in 4 different lanes (labelled "A", "G", "C", and "T") of an electrophoretic gel. Which lane will contain the product that ran furthest down the gel
Answer:
The reaction with adenine dideoxynucleotides will run furthest in the gel
Explanation:
In dideoxy sequencing (also known as Sanger sequencing), the DNA template is used to run four different reactions in which only one class of dideoxynucleotide (ddNTP) is added. These four different ddNTPs (i.e., ddATP, ddCTP, ddTTP or ddGTP) act as terminators during DNA synthesis. Moreover, the additional factors required for DNA synthesis including standard deoxynucleotides (dNTPs), DNA polymerase and site-specific primers are added in equal volumes to prepare these four different reactions. Thus, during electrophoresis, the sizes of the DNA bands will depend on the specific ddNTP used in each reaction. In this case, the reaction containing ddATP (capable of terminating DNA synthesis at the 5' end) will run furthest in the gel.

ASAP When attempting to determine where plants get their food, how did soil measurements affect the experiments? A. Reduction in soil mass proved that plants get their food from the soil. B. The soil mass did not change, proving that plants do not get their food from soil. C. Increase in soil mass proved that plants do not get their food from the soil. D. Soil measurements were not involved.
Answer:
A. Reduction in soil mass proved that plants get their food from the soil.
Explanation:
Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.
A certain strain of E. coli is constitutive for the enzymes for lactose metabolism. On an F' plasmid you have the choice of adding one (but only one) element of the lac system to make the bacteria a merodiploid for that element. Assume the original E. coli has wild-type structural loci. If your goal is to determine whether the lac operon is constitutive because of a mutant regulator OR because of a mutant operator, which one wild-type element of the lac operon would you add using sexduction?
a. operator region
b. regulator (repressor)
c. gene promoter region
d. structural genes
Answer:
The correct option is B: regulator (repressor)
Explanation:
A regulator gene would be required to control the expression by either increasing or decreasing the transcription of that particular gene. In doing so, the amount of protein product made by the gene can be regulated. In the wild-type case, the gene lacl is responsible for generating the mRNA which translates to a Lac repressor protein that binds at the operator region.

The process of DNA replication is described. Identify the enzyme that participates in each part of the replication process. DNA partially unwinds as the hydrogen bonds between complementary bases are broken. This process is catalyzed by the enzyme
Answer:
Helicase
Explanation:
DNA replication is the process in which DNA makes copies of itself.
The process of DNA replication is supported by several enzymes.
The initial step of DNA replication is unwinding of double stranded DNA which is catalyzed by helicase enzyme. Helicase enzymes breaks the hydrogen bond between the DNA strands and prepare them for replication process.
Hence, the correct asnwer is "Helicase".
In the process of cellular respiration, glucose is broken down into simpler compounds. Respiration is carried on in the presence (aerobic) or absence (anaerobic) of free oxygen.
a. True
b. False
Answer:
a. True
Explanation:
Cellular Respiration is the process by which cells of all living organisms obtain the required energy for their metabolic activities. Respiration is a catabolic process whereby glucose is broken down to release Its high energy and used to synthesize a usable form of energy by the cell (ATP).
Cellular respiration occurs in living cells with oxygen (aerobic) or without oxygen (anaerobic). In aerobic respiration, three processes viz: Glycolysis, Kreb's cycle and Oxidative phosphorylation are involved. Oxygen is the final electron acceptor in the Electron transport chain of the Oxidative phosphorylation.
On the other hand, anaerobic respiration is employed by certain bacteria in the absence of oxygen. In anaerobic respiration, another final electron acceptor is used other than oxygen.
Both processes yield Adenosine triphosphate (ATP).

You ran an experiment in lab that produced the following gel-electrophoresis results. The smallest band recorded was 2.03 kb and the largest band recorded was 17.15 kb.Which well contained a 17.15kb fragment but not a 2.03kb fragment?
A. 1
B. 2
C. 3
D. 4
Answer: C
Explanation:
Gel-electrophoresis separate macromolecules according to their size and charge. In the exposed example, the well that contains a 17.15kb fragment but not a 2.03kb fragment is number 2 (Option B) (based on the attached image).
---------------------------------
Gel-electrophoresis is a technique widely used in labs to separate macromolecules, like DNA, RNA, and proteins.
This technique is based on the size and charge of the molecules. It expresses a pattern of differentiation according to the length of the fragments.
Once placed in the gel, molecules start their migration. Smaller molecules will travel faster and farther than the bigger ones.
So whenever we see a gel-electrophoresis result, we know that the largest fragments are placed in the first position, while the smallest ones are in the last position.
In the exposed example, we know that the smallest fragment is 2.03kb, while the largest one is 17.15kb.
We assume that largest fragment will be placed in the first position, and the smallest one will be placed in the last position.
First position⇒ Biggest fragment ⇒17.15kb⇒ They hardly migrateLast position⇒Smallest fragment ⇒2.03kb⇒Migrate faster and fartherWe need to find a well that has fragments of 17.15 kb but not fragments of 2.03 kb.
So let us find the well in which there are molecules in the first position but not in the last one.
Note: In the attached files, you will find a gel-electrophoresis result image on which I base my answer. If this image is different from yours, choose the correct well in your gel-electrophoresis following the same reasoning.
The correct well is Two (Option B). Molecules have migrated to the first position but not to the last one.

Would any of these genotypes affect your species’ survival in its natural habitat? Explain why or why not.
Hello. You did not enter the answer options, but I can help you by saying that a genotype would affect the survival of a species in its natural habitat if that genotype establishes a disadvantageous characteristic for that habitat.
For example: We know that the Arctic foxes have genotypes that allow them to have a white color very advantageous for their natural habitat. That's because the white color, makes the fox camouflage itself in the environment surrounded by snow and equally white. This allows the fox to go unnoticed by possible predators, that is, its genotype favors the survival of the species. On the other hand, if the arctic fox genotype established a red color in the animal, it would affect its survival, in relation to its natural habitat. This is because it had not allowed the animal to camouflage itself in the environment, leaving it exposed to predators.
Drag each tile to the correct box. Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.
Answer:
First the proprioceptors found in the tissues will capture tissue damage and the presence of a continuity solution in the skin, then these receptors will activate the afferent pathway, which is the pathway of pain, which is sensory.
This stimulus that ascends to the central nervous system activates the "flight" mechanism in the face of pain (it is also known as the withdrawal mechanism).
It is in this way that a stimulation is sent to the alpha motor neuron in the form of an action potential as an efferent pathway to the skeletal muscles of the foot and the damaged leg, so that an automatic and involuntary muscle contraction is generated in a matter of millisemas of second after the damage, so the foot is removed from the damage area.
Explanation:
The withdrawal mechanism is a reflex that the human acquires before pain, that is why it is the muscular contraction is automatic and fast once the pain occurs.
So as a summary: 1 - the proprioceptors of the damaged tissue are activated 2- the signal of tissue damage rises as afferent to the CNS 3- the CNS responds by activating a signal that will be sent by interneuronal connections to the alpha motor neuron 4- the signal arrives as potential of action to the alpha motor neuron that innervates the muscles of the surrounding area to which it is damaged 5 - the muscles contract, generating the withdrawal of the limb.

O A. Fragmentation
OB. Transform
O C. Convergent
O D. Divergent
The type of plate boundary that an image is expressing is known as convergent. Thus, the correct option for this question is C.
What do you mean by Plate boundary?A plate boundary may be defined as a type of location where two specific plates meet. These boundaries are generally associated with numerous geological events like earthquakes.
According to the context of this question, plate boundaries govern the three-dimensional surface or zone across which there is a significant change in the velocity that may take place.
Convergent plate boundaries may be characterized as a type of plate boundary when two or more specific plates come together in such a way that they meet. At this boundary, two or more lithospheric plates collide. One plate eventually slides beneath the other.
Therefore, the type of plate boundary that an image is expressing is known as convergent. Thus, the correct option for this question is C.

Answer:
Transcription begins in the nucleus when RNA polymerase unzips a DNA molecule.
RNA nucleotides align themselves to complementary base pairs and in this manner messenger RNA is formed.
In eukaryotes must be processed before it leaves In the nucleus.
One end is modified with the addition of a cap and the other end is modified with the addition of a poly-A tail. Some sections called introns are edited out, leaving only exons remaining.
Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation
Explanation:
Transcription is the process in which DNA becomes RNA. In this protein synthesis, transcription occurs in the nucleus while translation in the cytoplasm. In the first one, which is transcription, a messenger RNA is produced. In the seceond one, an amino acid sequence is produced in the ribosomes.
*Take into account there were two options missing that I added because they were the only correct answer. "In eukaryotes must be processed before it leaves In the nucleus" the only right answer is eukaryotes, because prokaryotes don't have nucleus. The other situation was in "Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation" the only option given was "transcription". The right answer is "translation" because this one occurs in the cytoplasm, and transciptrion in the nucleus.

a) the F1 generation;
b) the F2 generation;
c) the progeny of a cross of the F1 plants back to the white, spiny parent; and
d) the progeny of a cross of the F1 back to the purple, smooth parent.
Answer:
See attached image for detailed punnet squares and diagrams
a) F1 generation: Purple flower and spiny pods (PpSs) offsprings
b) F2 generation: Puple flower, spiny pods (9), Purple flower, smooth pods (3), White flower, spiny pods (3), white flower, smooth pods (1).
c) The progenies are: PpSS (4), PpSs (4), ppSS (4), and ppSs (4)
d) The progenies are: PPSs (4), PPss (4), PpSs (4), Ppss (4)
Explanation:
This question involves two distinct genes in jimsonweed; one coding for flower colour and the other for pod texture. The alleles for purple colour (P) and spiny pods (S) are dominant over the alleles of white flower (p) and smooth pods (s) in the two genes respectively.
A true-breeding plant with white flowers and spiny pods will have genotype: ppSS while a true-breeding plant with purple flowers and smooth pods will have genotype: PPss. In a cross between these two parents, the following combinations of gametes will be produced:
ppSS- pS, pS, pS and pS
PPss- Ps, Ps, Ps, PS
a) Hence, the F1 offsprings from this cross will possess a heterozygous genotype: PpSs, which is phenotypically purple-flowered and spiny-pod.
b) if the F1 offsprings are self-crossed i.e. PpSs × PpSs, gametes PS, Ps, pS, ps will be produced by each parent. These gametes will be used in a punnet square (see attached image) to produce the following F2 offsprings in proportion:
Purple flower, spinny pods (9)
Purple flower, smooth pods (3)
White flower, spiny pods (3)
White flower, smooth pods (1)
c) if the F1 offsprings are crossed back with the white, spiny parent i.e. PpSs × ppSS. The following progeny of offsprings will be produced: (see attached image)
PpSS (4),

So far, we have examined a cell that does not undergo crossing over. What is true about such a cell?
b. It will produce a limited variety of gametes with certain alleles being always passed on together.
Crossing over is a process that happens during meiosis, where the 23 chromosomes from the mother mixes with the 23 from the dad, creating an individual with an unique combination of genes. The only chromosome that does not do crossing over is the chromosome Y, because it is too different from his counterpart, the chromosome X.
Which statement is best supported by the data in the graph? A graph entitled Number of people living with H I V, number of people newly infected with H I V and number of AIDS deaths worldwide from 1990 to 2008 in millions is shown. Year is on the horizontal axis and number of people is on the vertical axis. The number of people living with H I V steadily increases over the years. The number of people newly infected increased from 1990 to 1996 and then began to decrease. The number of deaths due to AIDS increased from 1990 to 2002, and then began to level off and decrease. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV. Since 1990, both the number of new HIV infections and the number of deaths due to AIDS has consistently increased. The life span of a person living with HIV has become shorter. Twice as many people were living with HIV in 2008 than in 2000.
Answer: A. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.
Explanation:
The statement "Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV" best supported by the data in the graph. Hence, option A is correct.
What is HIV?The virus known as HIV (human immunodeficiency virus) targets the immune system of the body. HIV can cause AIDS (acquired immunodeficiency syndrome) if it is not treated. Right now, there is no efficient treatment.
Nevertheless, since 1996, there have been fewer new infections. For this reason, we can assume that if we look at the year 2000, we will observe that there was a rise in the number of HIV-positive persons but a decline in the number of HIV-positive people.
Therefore, since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.

Research suggests that mitochondria and chloroplasts are modern-day descendants of ancient prokaryotes that were engulfed by ancestral eukaryotes. DNA is present in both of these organelles, which represents the only location for DNA in a eukaryotic cell outside of the nucleus. Briefly explain how this DNA evidence strongly supports this theory of endosymbiosis.
Answer:
Explanation:
Mitochondria and Chloroplast contain some Ribosomes which are different from the cytoplasmic ribosomes,These were measured to be 80s,while the Mitochondria and Chloroplasts are 70s.
Furthermore smaller circular DNA were found in theses two organelles,(which are the first DNA outside nucleus).These DNA types are the exact forms found in bacteria.
Thus, it was concluded that if these organelles could contained these genetic materials,they must be bacterial.Therefore chloroplast and mitochondria were ancient bacterial which now live in a mutual exclusive relationships in the larger cells of Eukaryotas(plant and animals).This is the basis of Endosymbiont theory.
That is these organelles live inside(Endo) new host in symbiosis or beneficial association with one another (symbiont).
A person who has Diabetes has difficulty controlling the glucose levels in their blood and must take Insulin to regulate it. Which characteristic of life do they need assistance with?
Based on the given information I believe this will help:
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).
If you have more sugar in your body than it needs, insulin helps store the sugar in your liver and releases it when your blood sugar level is low or if you need more sugar, such as in between meals or during physical activity.
If your body does not produce enough insulin or your cells are resistant to the effects of insulin, you may develop hyperglycemia (high blood sugar), which can cause long-term complications if the blood sugar levels stay elevated for long periods of time.
Treatment:
People with type diabetes cannot make insulin because the beta cells in their pancreas are damaged or destroyed. Therefore, these people will need insulin injections to allow their body to process glucose and avoid complications from hyperglycemia.
