Answer:
O Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals
Explanation:
Vestigial organs are defined as the organs which are no longer beneficial for survival.
Whales can be observed with tiny, unused hip and pelvis bones which are vestigial organs for them as they are no longer beneficial for their survival. The vestigial organs are the evidence of evolution in organisms and in whales also these vestigial organs says that whales and land-dwelling animals may have common ancestors. Later on with evolution some land-dwelling animals might move to water systems and hip and pelvis bones become vestigial organs for them which along with time decreasing in the future offspring.
Hence, the correct answer is "Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals".
Answer:
Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly.
hope this helps :D

Answer:
Option C. Heat energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules.
Explanation:
Aerobic respiration js is a type of respiration in which food molecules i. e. glucose is broken down with the addition of oxygen forming carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). The glucose contains chemicals energy and releases when it is burn.
