Answer:
Gradually, as generations of elephants continued to selectively use and develop their trunks.
Explanation:
Jean-Baptiste Lamarck was famous French Naturalist. He was a soldier, a biologist and an academic. He gave an early theory of evolution known as the theory of Lamarckism.
It was Lamarck who first believed that elephants earlier had small trunks. But eventual when there was scarcity of food and water, the elephants stretched out its trunk to reached out for food such as trees and also water. And as a result their offspring inherited long and powerful trunk.
In his theory of Lamarckism, he believed that the species passes on its traits to the offspring which they acquired through their use in their lifetime. In this case, the elephants might have used their trunks in such a way that they became long and strong over time and they passed tis trait to their babies.
Hey there mate!
Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.
But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.
So, it really depends whether the system closes up, or whether it would be free of energy.
So, in this case, your correct option to this answer would be (option A).
<span>In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after.

Answer:
They either get their source of nutrients from something else. Or, they could also have shorter roots so that they only reach the top of the soil. They probably won't need as much nutrients to survive either.
Explanation:
Six distinct antibody subtypes can be produced in response to the antigen.
It is assumed that a certain antigen has six distinct antigenic determination sites.
To find out how many various types of antibodies this antigen can trigger production of, read on.
A molecule, chemical structure, foreign particle, pollen grain, or any other substance that can attach to a particular antibody or T-cell receptor is referred to as an antigen.
An epitope is an antigenic determinant, which is the component of an antigen that the immune system recognizes.
An antibody is a large, Y-shaped protein that the immune system employs to recognize and destroy foreign substances like dangerous germs and viruses.
