Compare and contrast mitosis and meiosis in terms of where and when they occur and their products.

Mitosis: Occurs in somatic cells during growth, development and healing. Produces two genetically identical daughter cells from one parent cell.

Meiosis: Occurs in germ cells during gamete formation for sexual reproduction.

Produces genetically different four daughter cells from one parent cell.

Explanation:

Mitosis is the cell division that occurs during growth and healing process in somatic cells. It gives rise to two diploid daughter cells from one diploid parent cell. The daughter cells are genetically identical to the parent cell.

Meiosis is the reductional cell division and occurs in germs cells for gamete formation. It forms four haploid daughter cells from one diploid parent cell. The daughter cells also carry some new gene combinations.

answer; ///(b) it is composed of four protein chains and four heme groups;

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
