Which two hormones influence the endometrium to thicken and prepare for implantation?
a.) progesterone and follicle stimulating hormone (fsh)b.) progesterone and luteinizing hormone c.) estrogen and luteinizing hormoned.) progesterone and estrogen

The correct answer is: d) progesterone and estrogen

Progesterone is a steroid sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis with a wide range of functions. It is called hormone of pregnancy.

Estrogen is the primary female sex hormone involved in almost all of the phases of the development and regulation of the female reproductive system.

Progesterone and estrogen work together during the luteal phase of the menstrual cycle causing the lining of the uterus to thicken more in order to prepare for possible fertilization.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
