Which of the following is a type of fine soil that is deposited by wind? a) erg b) dune c) loess d) ventifact

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

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 : )
