Answer 1

Hint: Oxytocin is the hormone released by the posterior part of the pituitary gland. It is one of the happy hormones that is released by the body. Prolactin is also known as lactotropin and is a protein present in the females.

Complete answer:
-Oxytocin is regarded as the happy hormone. It is also released in huge amounts during labor and after labor to induce stimulation of the nipples. Its main role is to induce labor and help in the muscle contraction of the uterus to eject out the embryo.
-Prolactin is the hormone secreted in the mammals. It induces the growth of the mammary glands present in the breasts. It promotes their growth and prepares them for the production of milk. This hormone is also responsible for the production of milk in the women after they give birth to their child. An excess level of production of this hormone can cause tumors in both males and females. It can lead to milk production in women who are not pregnant.
-Luteinizing hormone is present in the pituitary gland in both males and females. In females, they control their menstrual cycle by controlling the formation of the egg. It triggers the release of the egg from the ovary. It has an important role in the sexual development and functioning of a body.
-Progesterone is the hormone which is a steroid hormone produced in the body of females. It helps in the preparation of the endometrium of the uterus which will help in pregnancy. It also helps in the implantation of the embryo to the placenta formed by it. It prevents the muscle contraction of the uterus that would cause the body to eject an egg.
So, the answer is ‘a-s, b-r, c-p, d-q’.

Note: These hormones are necessary for a female body to induce their reproductive cycle. They help in regulating the ejection of the egg from the ovary and also help in the implantation of the egg to the uterine wall and prevent any miscarriage to happen.
