B. Plastron is the bottom half of a turtle's shell
Answer:Organ
Explanation:An organ may be defined as a group of tissues which perform similar functions. Organs can be found in both plants and animals,functionally related organs often cooperate to form systems. These organs are interdependent on each other to make up organ systems. Organ systems can be found in the different parts of the body. For instance,the esophagus,stomach and liver make up the digestive system and in the excretory system the skin and kidney are examples of the organs that can be found here. The main tissues of an organ tend to have the same embryological origin. This simply means that they arise from the same germ layer and by germ layer we mean the primary layer of cells that form during embryonic development. In plants however,the main organs are the roots,stem and leaves whose primary functions are to give nourishment to the plant. Reproductive organs of plants include the seed,flowers and spores which maintain the basic life processes of the plant.
The use of restriction enzymes is evidenced by the statement 'cut site mCYCF3E 685' (Option A).
<h3>What are restriction enzymes?</h3>
The restriction enzymes are proteins (enzymes) that cut specific sites in the nucleotide sequence.
In this case, the enzyme cuts the gene mCYCF3E at the position number 685 (nucleotide base).
In conclusion, the use of restriction enzymes is evidenced by the statement 'cut site mCYCF3E 685' (Option A).
