1. Anaphase. In Anaphase the sister chromatids separate from each other to the opposite sides of the cells.

2. Chromosomes would not separate into two nuclei. Mitosis is a process cell division, where one cell divides into two identical cells.

3. Metaphase I. Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.

4. Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. In the gametes, there are half of the number of chromosomes present in the body cell.

5. A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

6. 50 percent.
Parents: Yy x yy
Offspring: Yy Yy yy yy
50 % is Yy and 50% is yy.

7. One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents: Rr x rr
Offspring Rr Rr Rr Rr

8. Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.

9. Not enough information.

10. Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents: Pp x Pp
Offspring: PP Pp Pp pp
One of the four is white.

Explain the relationship between DNA, RNA, proteins, and phenotypes: DNA

Y_Kistochka [10]

Answer: Basically, DNA holds to code for making RNA. The process of making RNA from DNA is called transcription.

After the RNA that is made, it goes to a ribsome. Ribsomes use the RNA sequence to make an animo acid sequence, which are proteins. The processes of using RNA to make proteins is called translation.

These proteins are what make you up! They are responsible for your different phenotypes.

Answer:

E-You disagree because the resulting increase in phytoplankton at the surface would inhibit sunlight from penetrating into the water, thus inhibiting photosynthesis in the submerged plants.

Explanation:

Eutrophication is the process wherein nutrients specifically phosphorus and nitrogen are present in excess in a water body such as a lake. The increased concentration of nutrients promoter the growth of cyanobacteria and algae such as phytoplankton.

The increased population of phytoplankton in surface water reduces the oxygen availability and clarity of water for the organisms present in deeper layers. Also, reduced clarity of water limits the amount of solar radiations penetrating the surface water to reach the deeper layers.

Increased nutrient levels of the lake would rather inhibit the growth of submerged plants due to reduced availability of sunlight as caused by presence of phytoplankton in surface water.
