Answer: genetic variation is a mutation or a change in the sequence of DNA. It can be preserved if that sequence is needed for a species to survive ( evolution). It can also be preserved if that sequence is strong enough to be passed down from mother to child. The mutation can be eliminated if it causes distress to the animal or if it makes the animals chances of survival smaller. If an extra fin on a dolphin helped it to better escape its predator and better obtain food then this trait may stick around because it is beneficial to the species. If the fin cause the dolphin to swim slower then the dolphin may not survive to reproduce or the trait will not pass on.
Explanation:
Meiosis is two rounds of genetic seperation while, mitosis only has one. Both of these process of cell division and replicating is associated with cytokinesis.<span>The end result of both are daughter cells produced from a parent cell</span>
It would be C
<span>Deflation is wind activity which also causes rock erosion or transports sand and dirt.</span>
Your answer would be B on Eddgenuity.
<span>It is the superior surface of the medial and lateral condyles. The medial condyle is a projection on the lower extremity of the femur, and the lateral condyle is the other projection on the lower extremity of the femur. The medial condyle is larger than the lateral as it bears more weight from the body.</span>
