A cell of an organism has four chromosomes. It undergoes a process at the end of which two daughter cells are produced. Each daughter cell has four chromosomes. Which process is described?

Answers

Answer 1

Answer: Mitosis

Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells.

clonal selection of lymphocytes leads to the development of which type of cells? a. effector cells and b cells b. t cells and memory cells c. effector cells and memory cells

Answers

b. t cells and memory cells

These immune cells produce a proper response chemical to combat the microbes. The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it .
