Blababa [14]

Answer:

Pregnancy, which is characteristically associated with changes in hormone levels in the body is a process tightly regulated by the hormon Human Chorionic Gonadotropin

Explanation:

The so-called pregnancy hormone is the Human Chorionic Gonadotropin (HCG). It only occurs during the gestation period and is responsible for regulating the entire process. Segregated by the placenta, it can be found in urine and blood.

The presence of the hormone in the urine allows to confirm the pregnancy with the test.   As in pregnancy, the placenta begins to form, the cells that make it up begin to stimulate the production of HCG, which causes the hormone levels to increase very rapidly in the first trimester of pregnancy

Andrei [34K]

Answer:

Seeds- form through <u><em>sexual </em></u>reproduction and contain an embryo that gives rise to a new plant.

Explanation:

The formation of seeds occur when a ripened ovule is fertilized by pollen. If the pollen and the ovule are from the same plant, then it is termed as self-pollination. If the pollen fertilizes the ovule of another plant then it is known as cross pollination. The seed contains the embryo which has the capability to form and generate into a new plant. Hence, the formation of seeds is a phenomenon which occurs in sexually reproducing plants.
