Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

Answer: The correct answer for the fill in the blank is ATP.
ATP ( adenosine triphosphate) is considered as the energy currency of the cell. The energy captured from the food by the living organisms is stored in ATP. It a high energy containing molecule. The energy is stored in its high energy chemical bonds, called as phosphoanhydride bonds ( between phosphate molecules).
Whenever the body requires energy, hydrolysis of ATP takes place ( ATP is converted to ADP and inorganic phos[phate). This results in the release of the stored energy.
Thus, most potential energy captured from food molecules is stored as ATP.
A. assemble amino acids
Mycorrhizae are fungal colonies that are in a mutualistic relationship with plants. These fungi help the plant absorb more nutrients and water from the soil, while the plant provides the fungus with carbohydrates that it generates through the process of photosynthesis. Mycorrhizae do not carry out the assimilation of amino acids, this is a process carried out the plant by itself.
DNA fulfills the function of replicating itself, which is a process in which identical copies of each molecule of the same are made. This replication is essential so that the genetic data can be transferred from one generation to the next, constituting the basis of the inheritance.
<span>The mechanism is given by separating the two chains of the helix from it, to serve as a template in the formation of new chains, which are called messenger RNA. Which are the result of two molecules equal to the first. This replication is called semi conservative, since each molecule resulting from the replication has one chain of the mother molecule and another newly created one.</span>
