Which of the following results from the incomplete breakdown of glucose that occurs under anaerobic conditions?

A. Luteinizing hormone (LH) is involved in the regulation of the menstrual cycle and ovulation, but it is not responsible for uterine contractions or milk production.
B. Lactogen (also known as human placental lactogen) is produced during pregnancy and helps prepare the breasts for milk production, but it does not trigger uterine contractions.
C. Oxytocin plays a key role in both uterine contractions during labor and milk ejection during breastfeeding. It is sometimes referred to as the "love hormone" because it is also involved in bonding and emotional connections.
D. Prolactin is responsible for stimulating milk production in the mammary glands, but it does not cause uterine contractions. Oxytocin is the hormone responsible for that function.

A. Oogenesis is the process of egg cell (ovum) formation in females and is responsible for producing gametes, not somatic cells.

B. Spermatogenesis is the process of sperm cell formation in males, also producing gametes, not somatic cells.

C. Mitosis is the process that produces somatic cells. It is a type of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell. Somatic cells are all body cells except for gametes.

D. Meiosis is the process that forms gametes (sperm and eggs), reducing the chromosome number by half to ensure sexual reproduction results in a normal chromosome count. It does not form somatic cells.
