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.

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.

Question 8 (5 points)
A molecule will become an ion when which of the follow happens
Answer:
An atom is known to become an Ion when it undergoes a chemical reaction. This is become chemical reactions occur as a result of loss or gain of electrons.
When this occurs the atom is said to become an ion.
When am atom gains electrons it becomes negatively charged and is referred to as an anion while when it loses electrons it becomes positively charged and is referred to as a cation.
Answer:
When it loses or gains an electron.
Explanation:
A molecule becomes an ion when it loses or gains an electron. Gaining or losing a molecule of ATP doesn’t make a molecule an ion, and it doesn’t matter whether the molecule is in a hypertonic or hypotonic solution. Moving through a semipermeable membrane isn’t a contributing factor to a molecule becoming an ion.

why would measuring just root mass not be a totally accurate way of measuring the effect of fertilizer on root growth
Answer:
Fertilizers affect the root growth in several ways such as:
Provide muti-nutritionsProvide more mineral nutritionSlow release of nutrients in soilRapid growth of plant rootRoot mass of root is the measurement of growth in length and weight of the roots.
So, the effect of fertilizer is not limited to the growth in length and weight, there are several nutritional changes in roots which are also important for the measurement of effect of fertlisers on root growth.
Answer:
The correct answer is - there are several other factors that affect the growth of the roots other than fertilizers.
Explanation:
Measuring the root mass only is not a correct or accurate way of measuring of the effect of the fertilizers on root growth as it is not the only factor that affect growth of the roots.
The factors that have significant effect on growth of roots of the plant are environmental conditions that are present in the root zone such as gas exchange, Water, Space, Carbohydrates, Non-limiting Temperature, Minerals, Microbial Associations and Low Soil Density.
Thus, the correct answer is - there are several other factors that affect the growth of the roots other than fertilizers.

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.
1. Are most invasive (exotic) species K-selected or r-selected species? Explain your choice and why that makes sense in terms of their ecological success.
Answer:
The correct answer is "r-selected species".
Explanation:
The terms "k-selected" and "r-selected" species are used to describe two different type of evolutionary strategies. K-selected species are those who have few offspring that are well adapted to its environment and require a lot of resources to growth and survive. On the other hand, r-selected species have a large number of offspring, which not require living on stable conditions and can survive with few resources. The most invasive species are r-selected, since they reproduce very quickly and can adapt to survive to very different ecological conditions.
A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in
the laboratory
Which statement best provides evidence that the substance is a mutagen?
The cells die within hours of being exposed to the chemical.
The cells grow more quickly than those that were not exposed to the chemical.
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
The cells continue to divide at the same rate as before they were exposed to the chemical.
Answer:C
Explanation:it’s 100% C
If a scientist thinks that a certain chemicals is a mutagen and expose plant cells to a large amount of such chemical in the lab, the statement that best provides evidence that the substance is a mutagen would be that the cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
A mutagen is generally described as a chemical that is capable of causing mutation in cells. Mutation in itself refers to heritable changes to the genome of a cell or an organism.
Hence, if a chemical is suspected to be a mutagen, such chemical must be able to cause mutation in the cells if they are exposed to it in large amount. The chemical should force some changes to the cell and the changes should be inheritable by the next generation of cells.

A biologist at World University used Procedure IV to conduct an additional study and found the sequence following below. Using your knowledge of central dogma generate the amino acid sequence that results from this sequence. Given DNA sequence: CAC GAC GGA TTC GTA
Answer:
Valine-Leucine-Proline-Lysine-Histidine
Explanation:
The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
N.B: Thymine is replaced by Uracil in the mRNA
For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)
Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
GUG specifies Valine amino acid
CUG specifies Leucine amino acid
CCU specifies Proline amino acid
AAG specifies Lysine amino acid
CAU specifies Histidine amino acid
When The central dogma generates the amino acid sequence that results from this sequence is: Valine-Leucine-Proline-Lysine-Histidine
What is a DNA sequence?
When The central dogma of biology is the process by which DNA is used to synthesize RNA and also subsequently amino acid sequence (PROTEIN). Then The processes of transcription and also translation is used in gene expression. Transcription is the process whereby the transmission encoded in a DNA molecule is useful to synthesize an mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which operates complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
Then, N.B: Thymine is replaced by Uracil in the mRNA
After that, For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
The translation is the second procedure of gene expression which
implicates the synthesis of an amino acid sequence from an mRNA molecule. When The mRNA is read in a group of three nucleotides called CODON. Individually codon identifies an amino acid (see attached image for genetic code)
Established on the connected genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid succession: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
Then, GUG specifies Valine amino acid
Now, CUG specifies Leucine amino acid
After that, CCU specifies Proline amino acid
Then, AAG specifies Lysine amino acid
Now, CAU specifies Histidine amino acid

The Lannister’s family went to bed one frigid winter night and were found deceased the next day. A squirrel’s nest was found in their chimney. What happened to the Lannisters?
Answer:
They died due to suffocation.
Explanation:
The whole Lannister’s family died due to the shortage of oxygen in the room because of squirrel’s nest in the chimney. Chimney is the only way for the removal of toxic gases and smoke produced from the burning of wood. The squirrel’s nest block the passage and the smoke and toxic gases stay in the house which causes suffocation and the whole Lannister’s family died.

narrowing of the coronary arteries due to buildup of debris along the artery
Answer:
The correct answer is coronary artery disease.
Explanation:
The narrowing of blockage of the coronary arteries, generally resulting due to atherosclerosis is known as coronary artery disease. Atherosclerosis also is known as the clogging or hardening of the arteries and is the accumulation of fatty deposits and cholesterol on the artery's inner walls.
These fatty deposits of plaques can prevent the flow of the blood to the muscles of the heart by physically choking the artery or by resulting in unusual artery function and tone. In the absence of a sufficient supply of blood, the heart becomes deficient of the essential nutrients and oxygen it requires to function appropriately. This can further result in angina or chest pain.
list the uses of gibberelin
snap id is in my bio
Answer:
A group of plant hormones, which are accountable for growth and development is gibberellins. These hormones play an essential part in the initiation of seed germination. A lesser quantity, these hormones can play an essential function in elevating the speed of germination, and they instigate cell elongation so that the plants grow taller. The following are the essential uses of gibberellins:
1. Promote flowering
2. End seed dormancy
3. Increase the size of the fruit.
For the seeds to germinate, there is a need for seed dormancy to end, and this can be done with the use of gibberellins. The hormone also promotes the process of flowering, which helps in the production of more fascinating and larger specimens of flowers.
The flowering process also influences the rate of the growth of fruits. Gibberellins are also used in the generation of seedless fruits. The spraying of the hormone helps to enhance the size of the fruit.
Research each insect, then compare and contrast the life cycles. You will need to write your observations and thoughts down. Be sure to include and describe each stage of development. Your observations, descriptions, and thoughts should be at least 150 words in length.
Incomplete Metamorphosis Complete Metamorphosis
grasshopper butterfly
dragonfly ladybug
cicada housefly
cockroach honeybee
Answer:
Larva and pupa is present in complete metamorphosis while nymph is present instead of larva and pupa in incomplete metamorphosis.
Explanation:
Complete metamorphosis has four stages i. e. egg, larva, pupa, and adult while the incomplete metamorphosis has three stages i. e. egg, nymph, and adult. Grasshopper, dragonfly, cicada and cockroach have incomplete metamorphosis while ladybug , housefly, butterfly and honeybee have complete metamorphosis. Both type of insects lay eggs and after hatching a baby insect comes out called larva. After sometime this larva transforms from immature to mature, this stage is known as pupa. After pupa, the insect converts into an adult which is ready for reproduction. Nymph is a stage that comes in place of larva and pupa in incomplete metamorphosis. in this stage, the insect is small in size and lack of wings but in adult stage the wings appear.
