In a species of walruses, tusk size is controlled by a single gene that has only two alleles. The same species lives on two diff

erent sides of the Arctic Ocean. On one side, the amount of ice is much thicker and requires for walruses to have longer tusks to move out of the water. On the other side, the ice is not as thick and walruses have shorter tusks. Which of the following best describes the walruses in the two populations?
Adaptive alleles that are beneficial in one environment can be deleterious in another, due to selective pressures.
The species will eventually develop an intermediate tusk size in both populations.
The alleles of both populations will undergo directional selection to have the similar gene pools.
The species will risk decline if they continue to differ in allele frequencies and genetic diversity.

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot
Mama L [17]

Answer:

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."

Explanation:

The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact.  When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.
