Answer:
The function of DNA is tied to its structure. ... The sugars and phosphates link the nucleotides together to form each strand of DNA. When two strands of DNA come together, base pairs form between the nucleotides of each strand. Nitrogenous bases pair together in the following way: A-T and C-G.
The image here shows potential outcomes for chromosomes at a particular stage of meiosis. Which questions appropriately assess what is happening in the image. Select ALL that apply.
A) How does crossing over increase the outcome of meiosis?
B) How does fertilization increase genetic diversity in a diploid organism?
C) How does independent assortment increase genetic diversity during meiosis?
D) How many potential combinations result from chromosomes alignment during metaphase I?
E) How does chromosome methylation result in silencing specific genes during gamete formation?
According to the random arrangement of homologous chromosomes in the equatorial plane, the correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?
How does the random arrangement of tetrads occur?During metaphase 1, chromosomes' homologous pairs migrate to the equatorial plane. Once there, they randomly aline facing their kinetochores to the opposite poles.
The random arrangement of tetrads is different in every cell going through the meiosis process. This is because there is no equal alinement between two cells.
When tetrads arrange in the equatorial plane, there is no predetermined order. Each homologous chromosome of each tetrad faces any of the poles and then migrates to it while separating. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell.
This random order in the equatorial plane is what introduces variation into the gametes.
The correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?

One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bees, they are smaller in size and are mostly ectothermic. They live in harsh, dry scrub land habitats and forage mainly on underground tubers which are widely dispersed. Why you think this species evolved back to an ectothermic life style rather than staying endothermic like all other mammals
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.

7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.
Answer: This description is an example of camouflage adaptations.
Explanation:
The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

Using the law of superposition and the principle of cross-cutting relationships, which of the layers of rock in this image is younger than layer C and closest in age to layer C?
A: Layer A
B: Layer E
C: Layer D
D: Layer B
Answer:
D. Layer B
Explanation:
The correct answer is Layer B.
The law of superposition actually states that the sedimentary rock unit is at the bottom while the the youngest rock is at the top. The principle of cross-cutting relationships states in layers of rocks, a fault or intrusion that cuts through rock layers is younger than the rocks that it cuts through.
Layer B was actually formed after Layer C. This makes Layer B younger than Layer C and closest in age to Layer C. The intrusion, Layer D is the youngest of all.

Explanation:
Determine the rate of oxygen consumption at each temperature for comparison. Then divide the higher rate by the lower rate to obtain the difference (ratio) between the two temperatures. Round your answer to the nearest 0.1. It can be concluded that mouse respiratory rate (increases or decreases) when temperature is lowered. In this experiment there was a fold difference in respiratory rate at the two temperatures.
Answer:
In mice rate of respiration increases as the temperature drops.
Explanation:
As the temperature decreases, the respiration rate also decrease because the body needs less oxygen for the production of energy. But in the case of mice, the rate of respiration decreases and the reason is the fear. Results showed that the respiration increased in mice as the decrease in temperature occur, caused due to the fear instilled in the mice towards cold temperature so in mice rate of respiration increases as the temperature drops.
