1. One important feature of DNA is that it can be accurately copied and inherited from one generation to the next. Imagine if DNA was NOT accurately replicated. What errors could occur and how would they affect the offspring in the next generation
Answer:
Explanation:
If DNA is not accurately replicated it can lead to mutation. Mutation is a genetic disorder that occur when a change occur and affect the genome of an organism. It can be result in frameshift mutation shifting nucleotide arrangement.
When DNA is not accurately replicated, it could lead to formation of an entirely new protein different from the original which has a different function this could lead to a form of disorder in the offspring. The effect of this disorder depends on it severity.

Answer:
(1) by increasing carbon dioxide and decreases oxygen
The destruction of the rainforests will affect the balance of gases in Earth's atmosphere by increasing carbon dioxide and decreasing oxygen.
Rainforests, like the Amazon, are the world's greatest concentration of living trees. Through the process of photosynthesis, these trees contribute to the composition of the atmosphere that we enjoy every day and depend on to survive.
All trees perform photosynthesis, the fuel for this is carbon dioxide. This process then releases oxygen into the atmosphere as a by-product. For this reason, the destruction of the rainforests will affect the balance of gases in Earth's atmosphere by increasing carbon dioxide and decreasing oxygen.

Justin is a 24-month-old male with multiple food allergies, including milk, eggs, and peanuts. At six months old a cooking utensil that had been used to cook eggs touched his arm and his mother noticed a significant dermatological response. As a result, Justin’s pediatrician advised her to avoid eggs, cow’s milk, and peanuts in Justin’s diet until food allergy testing could be done at two years of age. Fortunately, Justin hasn’t had any negative reactions to soy milk. Food allergy testing has confirmed that Justin needs to continue to avoid cow’s milk and peanuts. His pediatrician plans to conduct food allergy testing annually and advises his mother that Justin will likely be able to outgrow the milk allergy. Justin is referred to a registered dietitian for an assessment of his growth and nutrition intake. His mother reports that he is able to feed himself and she has noticed no problems with chewing and swallowing. A 24-hour dietary recall shows Justin consumed the following foods:
Fortified soy milk (4 ounces), rice cereal, bananas, grilled soy-cheese sandwich, fortified soy milk (4 ounces), green beans, apricots, orange juice (8 ounces), apple slices, almond butter on toast, apple juice (8 ounces), roast turkey, baked potato, green peas, and fortified soy milk (4 ounces).

Assume a population of deer has a crude birth rate of 36 per 1,000/yr, a crude death rate of 20 per 1,000/yr, an immigration rate of 15 per 1,000/yr, and an emigration rate of 8 per 1,000/yr. What is the population growth rate
Answer:
0.023%
Explanation:
The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula
[tex]N/t[/tex] where N is the total change in the population size, and t is time.
When immigration and emigration are factored in, we now have the formula;
[tex](CBR +I) - (CDR + I)/1000[/tex]
[tex]= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\[/tex]

Since viruses are typically 20-200nm in diameter.. what is the best microscope to view them?
Answer:
electron microscope
Explanation:
Due to their extremely small size, the best microscope to view viruses would be the electron microscope.
The electron microscope has the capability to create resolved images of extremely small objects by utilizing electrons as a source of light instead of the visible light photon that is typical of light microscopes.
There are different two types of electron microscopes:
the scanning electron microscope, andthe transmission electron microscope.A typical scanning electron microscope creates an image of an object by detecting knock-off electrons from the object, whereas a transmission electron microscope uses electrons that pass through the object to create the image of the object.

A cylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with balls stacked near its bottom. How is energy related to the change of state represented by the model? Atoms gain energy as a gas changes to a solid. Atoms gain energy as a gas changes to a liquid. Atoms lose energy as a gas changes to a solid. Atoms lose energy as a gas changes to a liquid.
Answer:
C. Atoms lose energy as a gas changes to a solid.
Explanation:
Physical changes of matter take place by adding or removing energy from the matter.
In the given images, The left cylindrical is showing gas phase while the right cylindrical is showing a solid phase.
The process of conversion of gas into solid is called deposition. Deposition process takes place when atoms lose their energy and have high kinetic energy so they directly convert into solid and not into liquid.
Hence, the correct option is "C".

Cervical pregnancies are extremely rare. Women undergoing cervical pregnancies often experience unusual vaginal bleeding. In extreme cases, they may require a hysterectomy (removal of the uterus). Why do you think the symptoms and risk occurs with this type of ectopic pregnancy?
Answer
The places where the fertilized egg got implanted are not appropriate
for the fetus´ development. These places lack space and needed tissues.
Explanation:
Ectopic pregnancies occur most often in the Fallopian tubes, which are the structures that transport the eggs from the ovaries to the uterus. But some other times, ectopic pregnancies might also occur in ovaries, abdominal cavity, or in the cervix.
These pregnancies are not viable, this means that the fertilized egg can not survive. However, the firsts stages of its development seem to be normal and involve an increase in tissues surrounding the egg.
As the places where the egg got implanted are not prepared for its development, they might be harmed. These areas do not have enough space, nor nutritional tissues needed by the embryo. And as the fetus grows, it creates a constant pressure in the organ, that can make it burst. This provokes important bleeding that might cause the patient´s death if they are not properly assisted.
At first, the woman might feel the normal symptoms of pregnancy, like the lack of the period during the firsts months or breast sensitivity. But as the egg grows in the inappropriate place, there appear some new signs and symptoms, such as a light bleeding or pelvic pain. If the organ bursts, the bleeding might be so intense that the woman might be in danger.
Answer:
Bleeding would occur because the baby is growing near the vaginal canal, which leads to the outside of the body. The cervix is the bottom portion of the uterus, so if the uterus is damaged, the entire uterus may need to be removed.

Fast reproduction by binary fission enables bacteria to
cause infections in other organisms.
quickly modify their DNA to changing conditions.
change shape from coccus to bacillus.
transfer DNA from one cell to another.
Answer:
A.) Cause infections in other organisms
Explanation:
Binary fission helps the bacteria to cause infections in other organisms because of duplication of its genetic material.
Through fast reproduction in bacteria enables to cause infections in other organisms by binary fission.
How does binary fission help bacteria reproduce quickly?
During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells.
The two daughter cells are just like the parent cell. Binary fission can happen very rapidly.
In the process of binary fission, an organism duplicates its genetic material, or desoxyribonucleic acid (DNA), then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Many prokaryotic organisms like bacteria reproduce by the method of binary fission.
Therefore, the correct option is A that bacteria cause infections in other organisms.

Glycogen Synthase Kinase:_______.
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
B. Phosphorylates glycogen phosphorylase
C. Phosphorlyates Casein Kinase.
D. Is activated by the insulin signaling pathway.
Answer:
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
Explanation:
Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.
2. If a nucleus has 8 chromosomes, how many chromosomes will be present after Telophase I? 3. What advantage does crossing-over have in reproduction? 6. Compare and contrast spermatogenesis and oogenesis (where do they occur, how many gametes are formed, when do they develop, etc):
Answer:
Telophase I: 8 chromosomes composed of two sister chromatids
Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation
Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)
Explanation:
Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.
Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.

If the regulator protein of the arginine regulon is mutated such that it can not bind arginine, which of the following describes the phenotype of the bacterium with such a mutation?
a) inducible
b) repressible
c) uninducible
d) constitutive
e) none of these
Answer:
The answer is a repressive mutation (the term is similar to b option).
Explanation:
In bacteria, the arginine regulon consists of a dozen genes required during the transport and biosynthesis of arginine (arg genes), these genes are controlled as a single unit. In prokaryotes, the concept of regulon is similar to the operon; however, an operon is composed of a group of genes linearly localized on bacterial chromosome, while a regulon can be formed by genes localized in different chromosome regions. Moreover, in eukaryotes, this concept is also used in order to indicate a set of linked genes that are regulated by the same regulatory gene sequence. A repressive mutation in a positive regulator of the arg regulon may trigger the inhibition of arg genes by affecting their ability to bind arginine.
O Consider the diagram that depicts the lysogenic and lytic cycles. The steps of the lysogenic cycle are shown. In Step A, attachment and entry occurs. In step B, the provirus is formed. In step C, the cell begins to divide. In step D, the provirus leaves. In step E, the virus is replicated and assembled. In step F, lysis and release of the virus occurs. In which step of the diagram is the provirus formed? step A step B step E step F
The correct answer is Step B
Explanation:
The lysogenic and lytic cycles are processes of replication for viruses. These two processes involve different steps. In general, the first stage involves attachment and penetration as the virus enters the host cell. This step is followed by the provirus, which means the genome of the virus is integrated into the DNA of the cell, this step is also mentioned in the model as part of step B "the provirus is formed". Moreover, the formation of the provirus is key as the nutrients of the host cell and genome are used for replication. Thus, in the diagram, the provirus is formed in step B.

DDT was once considered a "silver bullet" that would permanently eradicate insect pests. Instead, DDT is largely useless against many insects because they are resistant. Propose a hypothesis as to why these organisms have become resistant to the chemical.
Answer:
None of the individual insects should have possessed genomes that made them resistant to DDT.
Explanation:
Pesticides such as DDT have been considered one of the best way to kill insects in the past. But with time, farmers have observed that this is not an authentic method. This is because the insects can gain resistance to the pests if they are exposed to the pesticide again and again. Even they could transmit these resistant genes in their offsprings. Hence, DDT will become useless against insects over time.
Describe the biosynthetic pathway that produces catecholamines such as norepinephrine and epinephrine from amino acid precursors and explain how the lack of available amino acids precursors would impact homeostasis regulated by catecholamines.
Answer:
Tyrosine and phenylalanine are amino acids required for the synthesis of catecholamines
Explanation:
The catecholamines are hormones composed of a catechol ring group (benzene) and an amine lateral chain. One of the most common catecholamines is the neurotransmitter norepinephrine (noradrenaline). The biosynthesis pathway of the norepinephrine hormone includes the following steps: 1-tyrosine hydroxylase produces L-DOPA from tyrosine, 2-L-DOPA is subsequently tranformed into dopamine by the L-amino acid decarboxylase, and finally, 3-this chemical precursor is converted into norepinephrine by the action of the dopamine β-hydroxylase.
Phenylketonuria is a congenital metabolic disease associated with a decrease in the metabolism of phenylalanine (Phe), which is an amino acid residue that acts as a precursor of different catecholamines including dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). Dietary restriction of tyrosine and phenylalanine is the most common treatment against phenylketonuria.
Which sequence correctly represents the order of events during egg formation?
Answer:
The egg is made by the hen. It creates an embryo (the future chick, the little white spot that you see on the egg yolk) which will be fed by the yolk of the egg.
The yolk is a food reserve (called the yolk) for the chick in formation: by eating the yolk, the embryo becomes a chick.
The white consists of gelatinous proteins, which the future chick will eat during incubation, warm for 21 days under the hen.
The shell protects the embryo, the yolk and the white. It is made of two membranes that are made from calcium that the hen stores in her bones and intestines. In the chicken's belly, muscles spin the egg during training and give it its perfect shape.
The shell is made in such a way that it is difficult to the pan from the outside, but very easy to break it from the inside. So the hen does not crush her eggs when she is brooding, but the chick can come out easily!
It works pretty much the same for all birds, reptiles, fish ... that lay eggs. On them, moreover, oviparous animals.
Explanation:
