Relaxin
<span>Relaxin, secreted by the corpus luteum of the ovary as well as the placenta, is responsible for helping to inhibit uterine activity and to soften the cervix and the collagen in joints. Softening of the cervix allows for dilatation at birth; softening of collagen allows for laxness in the lower spine and so helps enlarge the birth canal. The effect of estrogen is to cause breast and uterine enlargement. Progesterone has a major role in maintaining the endometrium, inhibiting uterine contractility, and aiding in the development of the breasts for lactation. Human placental lactogen (hPL), also known as human chorionic somatomammotropin, serves as an antagonist to insulin, making insulin less effective, thereby allowing more glucose to become available for fetal growth.</span>
Answer: b. Webbed-toed mice survived better and reproduced more than mice without webbed toes.
Explanation:
Natural selection is a phenomenon that suggests that organisms that have a better structural and morphological advantage over the others have better chances of survival over the others.
The webbed toed mice have a survival advantage over the without the webbed toes because this can help the webbed toed mice to swim. The webbed toed trait will be beneficial and passed on to the next generation of the mice and the webbed toed mice will reproduce more than the mice without webbed toes.
They would because they need that water for growing plants and some crops grow on water.
