Example of Internal Stimulus - Option A

A decrease in oxygen levels in the blood during exercise is an example of an internal stimulus. It is happening within the organism itself, it will be internal stimulus. But a sudden change of air temperature is not occuring within the body of organism.

It is the change outside so it is external. An artificial light that attracts insects and an increase in the amount of water available to plant. Both are happenings which occur outside the body hence both are external stimulus. Only a decrease in oxygen levels in the blood during exercise happens inside the body so it is only internal stimulus.

Dafna1 [17]

Answer:

The correct answer would be - complex eyes evolved in the gradual steps, each of which was fully functional and adaptive in improving visual acuity.

Explanation:

The natural selection of the complex traits such as the vertebrate eye (complex eye) are seems to be problematic, many biologist think that the complex eyes evolution is take place in gradual steps and each step of this evolution was adaptive and functional in improving the visual acuity.

The steps that were involved are like light sensitivity patch, a deepening hole or pit that help in sharp vision and many other random evolution steps.

Thus, the correct answer is- complex eyes evolved in the gradual steps, each step of this evolution was fully functional and adaptive that helps in improving visual acuity.
