Answer: A.Reproductive isolation occurred through behavioral isolation.
Speciation is a process of development of new species from the previously existing species due to reproductive barriers occur among the members of the population of species. The reproductive barrier arises due to behavior and physical differences. Behavior isolation occurs when the two populations of the same species develop some differences in behavior, to attract their mates for mating, which can lead to reproductive isolation among members of same species or related species.
In the given situation, the related species of leopard frogs have developed specific courtship call, this will lead to reproductive isolation due to behavior isolation. This will help in identifying mates of the same species and this will act as a reproductive barrier among the other related species.
Answer:
b. to grow the population of their species.
Explanation:
Answer:
D
Explanation:
1. As given, the overall genome contain 50% G+C.
And the concept is that G is always pairs with C.
and A is always pairs with T.
So, in a dsDNA, A+G= T+C
2. As there that, there is a cluster of genes comprising about 20,000 bp that is 64% G + C so this so that the 20,000 bp segment is a recent acquisition via horizontal gene transfer.
Answer:
A. in order to release the energy found in food.
Explanation:
Every cell in your body needs oxygen to function. You get the oxygen your cells need from the air you breathe. The air you breathe is made up of 20 percent oxygen. The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. This is very similar to wood burning in a fire. As the wood burns, it combines with oxygen and releases heat energy and carbon dioxide. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. But instead of heat energy, much of the energy produced in cellular respiration is stored chemically for the cell to use later. Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs. The opposite takes place in the cells where the blood releases oxygen and picks up carbon dioxide.
Answer:
Yes, they are living things. How? Well I did my research with my browser and it doesn't have a lot to say but what it does say is That it is living.
