Question

You are part of the research group that hypothesized that relative humidity played a role in the transpiration differences. What additional evidence might you provide to support your hypothesis?

A) Population A has a high water potential and loss due to transpiration because of the increased humidity.

B) Population B has less water loss due to transpiration due to less crowding, less shading and an increase in humidity.

C) Population B shows an increased loss of water through transpiration because the environmental conditions are windier and less humid.

D) Population A has a low water potential and loss due to transpiration because more crowded conditions result in lower humidity and less shading.

Answer 1

A) Population A has a high water potential and loss due to transpiration because of the increased humidity.

Explanation:

Notice that the hypothesis is that relative humidity affects the transpiration of the body. So, in order to prove such hypothesis, we need to find enough evidence about water loss due to higher humidity. Knowing the relative humidity as the relation between water vapor and the pressure of it.

Therefore, the right answer is A, because we need to prove that a high water potential and loss due to transpitation happens because of the increased humidity.
