The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.
Answer:
The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.
Explanation:
Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.
To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.
As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.
The answer is B mutualism

Answer:
As the spies of a cactus are modified leaves, they have ar spaces.
Explanation:
However, leaves of cactus are not like every other leaf. These leaves are in the form of spines to save the amount of water that the cactus needs.
