Explanation:

Question 25

The thyroid gland secretes thyroxine (also known as T4). Thyroxine plays a crucial role in regulating metabolism, growth, and development. The spelling "thyroxine" is the correct one among the given options. "Thiroxine" is a misspelling, and "thyroixine" is also incorrect.

The breasts provide nourishing milk for the newborn (infant), not for the embryo. An embryo is in the early stage of development (up to 8 - week post - fertilization in humans). Milk production (lactation) occurs after childbirth to feed the baby.

Fertilization is the process where the sperm and egg fuse. In the female reproductive system, this typically occurs in the uterine (fallopian) tubes. After fertilization, the zygote then travels to the uterus for implantation.

Answer:

thyroxine
