Answer:
Prokaryotes are smaller and less developed compared to eukaryotes. Some of them inhabit very primitive environments that resemble earth’s early stages. Endosymbiotic theory states that eukaryotes arose by the endosymbiosis of prokaryotes.
Explanation
By endosymbiont theory, eukaryotic cells arise from prokaryotic cells. Here, the theory shows that eukaryotic ancestors lived in close association with prokaryotes, wherein in some cases, prokaryotes have been engulfed and might have lived inside eukaryotes.
Upon being engulfed by a host cell as undigested prey, these prokaryotes could have been internal parasites of the eukaryotes. But, later on, their relationship becomes mutualistic and these prokaryotes become incorporated as organelles, such as in the case of chloroplasts and mitochondria, which were previously separate prokaryotes

Answer:
a) How many genotypes will occur in F2
--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)
Reason-
This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.
b) 25% of all F2 genotypes would be recessive across the 5 loci
Reason-
This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.
c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE
d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE
Answer:
G1 - S - G2 (may be is option D)
Explanation:
The interface begins with phase G1 where the cell increases its volume and the mass is doubled.
Then, we continue with the S phase where DNA and histones are synthesized.
Afterwardsy we reach the G2 phase where the chromosomes are duplicated.
Finally we reach, the begining of mitosis.
Stage 1 - <span>The ear collects compression waves.
Stage 2 - </span>The ear amplifies the compression waves.
Stage 3 - <span>The amplified waves stimulate the hair cells of the ear.
Stage 4 - </span><span>The hair cells transmit nerve impulses to the brain
Stage 5 -</span><span>The brain interprets the nerve impulses.

Diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. The variance of the trait increases and the population is divided into two distinct groups. In the above question an example of diversifying selection is A population of moths with white and grey forms lives in a forest containing trees with light and dark bark.
