Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition
Explanation:
Amoeba: Also ameba. A single-celled (protozoan) organism that constantly changes shape. The word "ameba" is from the Greek "amoibe" meaning "change." Ameba can infect the bowels to cause diarrhea and the liver to cause abscess formation. Here is more information.

Answer:
D
Explanation:
Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons
Answer:
Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.
Explanation:
This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).
Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.
