5. When cells divide and multiply in the embryo and change in shape and structure, the process is called a. Duplication b. Differentiation c. Replication d. Osmosis

b. Differentiation

Explanation:

Differentiation can be defined as the process in which a cell changes from a generalized cell type into a specialized cell type for performing specific functions in the body. Therefore, when cells divide and multiply in the embryo and change in shape and structure, the process is called differentiation.

Generally, a generalized (less specialized) cell's shape, metabolism, size, membrane potential, polarity, and responsiveness to signals usually change to become more specialized in terms of form and functions in the body.

For instance, the single celled zygote in the human body differentiates into a multi-cellular embryo and subsequently changes to a complex system of tissues and cell types, in shape and structure.

i think life is life. many could argue that life is ‘nice’ or ‘fun’ but in the end, it is immaterial and will end. nihilism is my philosophy. nothing matters in the end so why make an effort?
