This type of cell is found in the blood and engulfs pathogens.
a. natural killer cells
b. cytotoxic
c. t cells
d. b lymphocytes
e. macrophages

The correct answer is macrophages

Explanation:

Macrophages are examples of phagocytes, and they engulfs pathogens (disease-causing organisms such as viruses, bacteria) by pulling them into their vacuoles and digesting them completely.

Macrophages, and Other like T-cells, B lymphocytes and natural killer cells all help in the BODY DEFENCE. But unlike macrophage, others exert their function through a different mechanism.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
