Answer:
In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.
Explanation:
The answer you are looking for is Natural Selection.
To provide energy to build new cells and tissue
Answer: Option E. DNA replication
Explanation:
DNA replication is described as anabolism because it involves the synthesis of newly synthesized strands of DNA from the double stranded parental DNA units.
Thus, since complex molecules are formed from simpler unit, DNA replication is an example of anabolism.
I would say B because when the whale slaps his tail, it moves.
