Answer:

Option D, the females choose mates

Explanation:

This is a common way to fertilize in animals where male put in efforts to allow the female to choose their partners. Here, in this case the male ducks are of different bright colors thus they would compete among themselves to attract the female ducks for mating. Therefore, a female duck gets the opportunity to choose the best partner for itself. This is a way of natural selection to fertilize.

Hence, option D is correct.

almond37 [142]

Fossil seashells have been found in rock beds on land. what can you infer about how the area has changed
olga55 [171]
When we go to the beach one of the most exiting activities that we do is of course collect the best looking seashells. Now I have never seen seashells in another place other than the beach.

 My point in this entery that I have just mentioned is that where there is seeashells there is body of water. What those fossils mean is that that particular place whhere those seashells were once found means that maybe a very long whille back that place was onetime a body of water. Some natural dissaster came and that place doughtet and the water moved to some place else.

How do pseudostratified ciliated columbar epithelium and transitional epithelium differ from other types of epithelia
yawa3891 [41]
Generally, epithelial cells serve the function of protection of the inner layers of the structure they are on. The fact that these columbar epithelium and transitional epithelium cells have smooth walls and are dome shaped allows them to stretch. This stretching helps the bladder retain more urine than it would be able to if the epithelial cells were rigid.
