Ventilation is the process by which air moves in and out of the lungs.Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
Answer:
The correct answer is - A. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.
Explanation:
In this experiment, the table shows that specific butterflies did not go to small flower trees or go once a day where is in medium and large flower trees respectively they visit more than small flowers.
Even after not visiting small flower trees the nectar energy and the fruit production is almost similar to the other two trees. This case can occur only in one case if there are one or more pollinators present in this scenario other than this type of specific butterflies.
Thus, the correct answer is - option A.
