1. If I view through low power objective 10x and ocular 4x, what is the total magnification of the microscope?
2. You have to study the detailed structure of a cell, which objective will be best to view it. Scanner, low power or high power, and why?
3. You are counting red blood cells, which objective will be best to count the number of cells, high power or low power objective, and why?
4. You see chromosomes lined up in the center of the cell. Which stage/phase of mitosis is it in?
5. You see sister chromatids moving towards the pole. Which stage/phase of mitosis is it in?
1. If a slide is viewed through a low power objective of 10x and ocular of 4x, the total magnification can be calculated thus:
Total magnification = objective magnification x ocular magnification
= 10 x 4
= 40
2. In order to study the detailed structure of a cell, a high-power objective comes highly recommended. This is because the high-power objective will magnify the essential details of the cell and enables the detailed structure of the cell to be seen.
3. In order to count red blood cells in a blood sample, an objective with a large field of vision comes highly recommended. The higher the magnifying power of an objective, the lower the field of vision. Thus, a low power objective would be the best for counting the red blood cells in a sample.
4. The stage at which chromosomes line up in the center of the cell during mitosis is the metaphase. Mitosis consists of 4 essential stages which are:
prophase: the stage at which the genetic materials in the cell condenses and become visible as chromosomes under the microscope.metaphase: the chromosomes line up at the center or the equator of the cell while spindle fibers engage each chromosome at the kinetochore of the centromereanaphase: chromosomes are pulled apart and separated into sister chromatids as a result of the shortening of the spindle fibers. Further shortening of the spindle fibers kick-starts the migration of sister chromatids towards the opposite ends of the cell.telophase: sister chromatids complete their migration to the poles. The chromosomes decondense and the cytoplasm of the cell divides in a process known as diakinesis.5. with reference to the explanation above, the stage of mitosis at which one would see sister chromatids moving towards the pole would be the anaphase.

.
The temperature gradient between points A and B is 0.1°C/m and keeping other conditions constant, if the mantle and the crust were closer to each other then the temperature gradient between the two would increase.
The temperature gradient between points A and B is 0.1°C/m. This means that for every meter traveled between the two points, the temperature decreases by 0.1°C. Therefore, the temperature difference between the two points can be attributed to their distance apart.
If the mantle and the crust were closer to each other, the distance between them would decrease. As a result, the temperature gradient between the two would increase. This is because a shorter distance would mean that there is less space for the heat to dissipate, leading to a greater temperature difference over a shorter distance.
The exact increase in temperature gradient would depend on the new distance between the mantle and the crust. However, it can be predicted that the temperature difference between the two points would increase as the distance between them decreases.
In summary, if the mantle and the crust were closer to each other, the temperature gradient between the two would increase. This would lead to a greater temperature difference over a shorter distance.

3. How is Acetyl-CoA prsluced during the acrobic oxidation of carbohydrates, and what happens to it? How is it produced during the aerobic oxidation of titty acids, and what happens to it
During the aerobic oxidation of carbohydrates, acetyl-CoA is produced through a series of metabolic reactions known as glycolysis and the citric acid cycle. During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation.
Pyruvate then enters the mitochondria, where it undergoes further processing to produce acetyl-CoA. This conversion occurs through a process called pyruvate decarboxylation, where pyruvate loses a carbon dioxide molecule and combines with coenzyme A (CoA) to form acetyl-CoA. Acetyl-CoA is a key molecule in energy metabolism and serves as a precursor for the citric acid cycle.
During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation. Fatty acids are broken down into two-carbon units, which then combine with CoA to form acetyl-CoA. This process occurs in the mitochondria, where fatty acids are sequentially cleaved into acetyl-CoA molecules. The acetyl-CoA molecules can enter the citric acid cycle to generate energy through oxidative phosphorylation.
Once acetyl-CoA is produced, it enters the citric acid cycle, also known as the Krebs cycle or TCA cycle. In this cycle, acetyl-CoA undergoes a series of enzymatic reactions, resulting in the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the electron transport chain to generate ATP through oxidative phosphorylation.

2. A rose- combed rooster is mated with two rose-combed hens. Hen A produces 14 chicks, all rose-combed. Hen B produces 9 chicks, 7 of which are rose-combed and 2 single-combed. What are likely genotypes of the parent? Explain.
Answer:
Explanation:
Based on the given information, we can use Punnett squares to determine the genotypes of the parent birds.
Let's use "R" to represent the rose-combed allele and "r" to represent the single-combed allele.
From the problem statement, we know that:
The rooster is rose-combed, so it must have at least one copy of the R allele.
Hen A produces 14 chicks, all of which are rose-combed. This means that Hen A must be homozygous for the R allele (RR).
Hen B produces 9 chicks, 7 of which are rose-combed and 2 of which are single-combed. This means that Hen B must be heterozygous for the R allele (Rr).
Using this information, we can set up Punnett squares to show the possible genotypes of the offspring from each parent:
Rooster: R r
---- ----
Hen A: R R R R
Offspring: R R R R (all rose-combed)
Hen B: R r R r
Offspring: R R R R (rose-combed)
R r R r (rose-combed)
r R r R (single-combed)
r R r R (single-combed)
Based on the Punnett squares, we can see that the rooster must be heterozygous for the R allele (Rr), since both hens produce only rose-combed offspring. Hen A is homozygous for the R allele (RR), while Hen B is heterozygous (Rr). This means that the genotype of the rooster is Rr, and the genotypes of the hens are RR and Rr, respectively.

correlate crossing-over with genetic linkage
Answer:
The closer together different genetic sequences are in the same chromosome the smaller is the chance of crossing-over/recombination among them
Explanation:
Genetic linkage refers to genetic sequences which are located on the same chromosome, and thereby they are usually inherited together during meiosis. On the other hand, crossing over (also known as recombination) refers to the exchange of chromosome fragments between non-sister chromatids during meiosis. In consequence, the closer together two genetic sequences are on the same chromosome, the lesser will be the chance they will be separated by crossing-over.

which type of moth do you think was more common before the 19th century, when most trees were light in color?
Answer:
Light-colored moths.
Explanation:
The process of Natural Selection, or survival of the fittest, says that only organisms with the most desireable traits will survive and reproduce. In an area with mostly light trees, dark-colored moths would have difficulty blending in with them, so they would be easily spotted and eaten by birds. If the dark moth population is reduced, only light moths will be able to reproduce, so their offspring will be light as well. Therefore, in an area with ligjt trees, light moths will evolve and be the dominant type since they can more easily hide from predators.
