When scientists use their five senses to learn new information, it is called:
o
a. drawing a conclusion.
o
b. making an observation.
o
c. forming a hypothesis.
o
d. the peer review process.

b) making an observation

Explanation:

The scientists are not drawing conclusions because they just learned new info. They are not forming a hypothesis because they are not predicting anything. And they have not used any peers. This is all coming from their senses and making an observation.

hope this helps :)

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 : )
