Answer: The population having one large claw will have more offspring as compared to the ones having smaller claw.
Explanation:
A population of crabs has two types of crabs in it, one with larger claw and other with smaller claw. They will try to attract the female crab in order to mate.
The males having larger claw are more attractive to the females. Females choose to prefer larger claw over smaller claw because they will have a big burrow which will help her incubate her eggs and they are older (survivor)because the crustaceans grow majority of their life.
So, the crab with large claw is likely to have more offspring than other one.
Answer:
Estrogen and progesterone are both involved in preparing the endometrium for embryo implantation. Estrogen helps to ensure conception by increasing the amount of secretory glands in the uterus. Estrogen also increases blood supply to the endometrium.
Progesterone is crucial for embryo implantation and maintenance of pregnancy. Progesterone also enlarges secretory glands that produce carbohydrates, proteins and mucin that are required for embryo nourishment before implantation. Progesterone stabilizes endometrial muscles to prevent them from contracting during pregnancy.
Explanation:
- Estrogen and progesterone are steroid hormones of the reproductive system. Estrogen helps in conception whereas progesterone maintains pregnancy.
- Estrogen is secreted during the follicular phase of the menstrual cycle that promotes the growth and maturation of follicles in the ovary.
- Estrogen also induces oestrous behavior in females.
- Secreted by the corpus luteum, progesterone is also a steroid hormone, responsible for implantation of the embryo in the uterus.
They are movement, homeostasis, and energy.
