Answer:
Option (B).
Explanation:
Genetic diversity may be defined as the number of total genetic characteristics of a species. Genetic diversity helps the population to adapt in the changing environment. Crossing over provides a source of genetic diversity.
Crossing over is the process of exchange of genetic material during the process of meiosis. Thus, crossing over increases the variation of genetic characteristic in the haploid gamete cells.
Thus, the correct answer is option (b).
Answer:
On the basis of the given information, that is, the ape exhibiting small incisors and biphodant molars, shows that they generally consume fruits and seeds as the prime part of their diet. Thus, mainly the apes feed on fruits, leaves, and seeds, thus it makes them vegetarian.
However, it has also been observed that canine teeth are found in both males and females, though they are larger in males. This shows that apes can consume meat from small birds and animals occasionally.
The answer is D.

Explanation:
the rule or reasoning I used to determine the change of how an object floats in the water is that paper can't float in water but blocks and others stuff can float.
Answer:
1. Cytoskeleton element that determines the cell diameter and is required for proper cell division - Bacterial cytoskeleton elements FtsZ.
2. Yields a high quantity of polypeptide in a short time interval - Polysome formation.
3. Is duplicated soon in the initial stage of DNA replication - Ori sequence.
4. Attaches the peptidoglycan to the membrane in Gram-negative bacteria - Lipoprotein
5. Cytoskeleton element found only in rod-shaped cells - MreB.
Explanation:
1. Fts Z protein ( Filamenting temperature-sensitive mutant Z) is present in bacteria that are homologous to the tubulin of eukaryotes. This protein plays an important role in the cell division of prokaryotes.
2. Polysome may be defined as the structure that contains single mRNA and multiple ribosomes known as polyribosomes. These polyribosomes increase the production of polypeptide chains.
3. The ori sequence may be defined as the DNA sequence at which the DNA replication initiates. The ori region multiple rapidly for the initiation of teh DNA replication process.
4. The bacterial membrane consists of lipids, proteins, carbohydrates and peptidoglycans. The lipoprotein is the association of lipids with protein that helps in the membrane formation of gram negative bacteria.
5. Mre B is an important cytoskeletal protein present in bacteria especially is rod shaped bacteria. This protein is homologoue to teh actin of eukaryotes.
