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.

2. Carbohydrate
3. Lipids
4. Carbohydrate
5. Lipids
6. Lipids
7. Carbohydrate
Explanation:
Lipids and carbohydrates are two of the four major biological molecules (the other two being proteins and nucleic acids). They (lipids and carbohydrates) are both long chains composed of elements: carbon (C), hydrogen (H) and oxygen (O).
Lipids called triglycerides are majorly made up of building block fatty acids (long hydrocarbon chains with carboxylic acid) and glycerol ( an hydrocarbon made up of three hydroxyll groups).
Carbohydrates, on the other hand, are made up of long chains of carbon, hydrogen and oxygen with aldehyde or ketone functional group. They are composed of monosaccharide building blocks (also called simple sugars) with general formula CH20(n).
Based on the structural composition of lipids and carbohydrates, structures 1,3,5 and 6 are lipids while 2, 4 and 7 are carbohydrates.
