Explain how mitosis is used for asexual reproduction

It is because mitosis also cell first makes the division of DNA or nucleus after that the division of cytoplasm takes place and thus the parent cell divides itself into 2 daughter cells which are like each other.

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 : )

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
