Answer: Option C) Animal
The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal
Explanation:
One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.
However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.
The answer is Convergence of images behind the Retina
Convex lens converges light to a principal focus. The thickness of the lens determines the focal length (distance between the center of the lens and the principal focal point). Therefore, by evaluating the thickness of the convex lens, farsightedness, (an eye defect of convergence of images behind the retina) can be corrected by enabling images in the eye to form behind the retina.
The question is incomplete as it does not have the options which are-
a. migration
b. genetic drift
c. mutation
d. stabilizing selection
Answer:
The correct answer will be option- migration
Explanation:
Migration refers to the long-distance movement of the individual, group and population. The migration enables the flow of genes from one population into another called gene flow. Migration is the strongest force of gene flow after selection.
In the given case, since the allele frequency of the population has changed due to the migration of the 200 snakes from a population of 5000 snakes, therefore, migration is the correct answer.
