Answer:
The correct answer will be option C- Convergent evolution.
Explanation:
The body shape of dolphins, sharks and penguins show similarity in structure sue to the same niche they inhabit which is the ocean.
All of them exhibit features which helped them survive in ocean-like streamlined bodies, fins and flippers. The dolphin, shark and penguins are not closely related but inherited similar characters (streamlined bodies, fins and flippers) due to the process of convergent evolution. These analogous features helped their survival in the same conditions.
Thus, option C- Convergent evolution is the correct answer.
<h3><u>Answer and explanation</u>;</h3>
- Glucose is extremely polar and fairly large compared to salt ions or gases like oxygen and carbon dioxide. Therefore, it can not freely diffuse in and out of the cell like other small ions and molecules or gases.
- Therefore, glucose molecules require transporters that either use energy directly or indirectly through concentration gradients set up by other energy-dependent transporters.
- Facilitated diffusion is the process where substances pass through the cell membrane, in a passive manner, with the help of transport molecules. Glucose is among the substances transported using facilitated diffusion.

Given what we know, we can confirm that the result of crossing over during meiosis I gives rise to new combinations of genes in the gametes at the end of meiosis.
<h3>What is meiosis?</h3>
It is the process of cell division that occurs in the gonads for the production of gametes that gives four haploid cells. During the crossing over, what will happen is that the homologous chromosomes exchange parts and new combinations are given for the gametes.
Therefore, we can confirm that the result of crossing over during meiosis I gives rise to new combinations of genes in the gametes at the end of meiosis.
