The questions are in the pic, they are about gravity :)

2. Because the gravitational force from anything that small compared to a planet is so minuscule it's nearly impossible to feel or measure.

3. Because do not have life and other processes necessary to create the gasses and substances necessary to create an atmosphere.

4. If the amount of mass lost was large enough it would likely allow the moon to eventually orbit away

is this a psat question, if so do not cheat try your best.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
