Answer:
<em>Hello There the Correct answer is A. Variations.</em>
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

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.
Answer: OPTION E
Explanation:unequal crossover usually leads to duplication or deletion of chromosome. In this case,. A DNa strand is deleted and replace usually by another DNA strand which is mostly a duplicate from a sister chromatid and this process leads to Gene families been produced beause one is deleted and again and again duplicate is produced on the same place (2 product formation). It is a form of chromosomal crossing over that exists between homologous sequence which were initially not paired together. In Gene duplication and mutation in organism, unequal crossover is said to be the pioneer or chief cause of it with Gene conversion beside it.
The third and last option is correct.
Species in the past (referring to dinosaurs) were more massive.
levels where higher in the past, which meant that plants prospered during that time since they had a easy access to food. That contributes to the fact that herbivores could grow bigger because there was more food. Which in turn, increases the size of early carnivores which eat bigger herbivores.
Hope it helped,
Happy homework/ study/ exam!
