- Circle the letters of the regions of the visible spectrum in which chlorophyll absorbs light very well.
a. blue-violet region
b. green region
c. red region

A) Blue-violet region.

Explanation:

Plants tend to absorb blue or violet light better than both green and red because their wavelengths are closer to UV rays. Red light is about average, and green light doesn't really help plants grow that well, maybe only a little bit depending on the scenario.

Have a nice day! :)

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 : )
