The most abundant tissue type by weight in the body .
a. epitheliab. nervec. connectived. muscle

c. connective

Explanation:

Connective tissue is the abundantly present tissue in the human or animal body. It is widely distributed and exists in varied type in the human or animal body. It includes the fat, bone, bone marrow, blood, cartilage, fibrous tissues. The function of the connective tissue is to provide the support and protection to the body. All connective tissues consists of fibers, cells and ground substances. The cells of the connective tissues include the macrophages, adipocytes, leucocytes, mast cells and fibroblasts.

The adipocytes are the cells which deposit fat in them. These cells are responsible for the majority of the weight in the body.

genetic variation will increase because of a new habitat and food source.

explanation:

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
