Help me on number 9 please!

D

Explanation:

I believe its D because we cross out the first 2 options because the question is asking about the dark line which is the pups and not the adults. if we look D and the lowest point of dark line, we can say its talking about few and 1995 talking about many.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this

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 : )
