larisa86 [58]

The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.

<h3>What is fitness?</h3>

Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.

It is a way of measuring the individual ability to leave fertile offspring.

Aptitude must be significant to the natural selection act in its favor.

In the exposed example we can see the survival rate of two species.

The survival rate is telling us about the fitness of each species.

  • The green beetle increases its survival rate (fitness) each year
  • The brown beetle decreases its survival rate each year

These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

Phototropism is the phenomenon that is causing the bean seedling to bend as shown.

Phototropism is known to be the growth of a plant or an organism in response to a light stimulus. This means that plants or organisms grow in the direction of the light. From the image shown, we will discover that the bean seedling is bending towards the direction of the sunlight.

This phenomenon usually occur in plants but it can also occur in organisms in fungi.

When the plants grow towards the direction of sunlight, it is known as positive phototropism while when the plants move away from the direction of sunlight, it is known as negative phototropism (skototropism).
