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.
Answer:
D
Explanation:
The plants in the light formed bubbles because they released oxygen gas, This is because bubbles that are formed takes the places of oxygen molecules O2. Oxygen is released during photosynthesis through the process called light-dependent reaction. The light-dependent reaction occurs only in the presencee of light. So, if bubbles formed are equivalent to oxygen molecules released in light-dependent reaction, then it is expected for bubbles to be found only on the leaves on those plants that were in a well-lit room.
You are looking at tissue under a microscope. One cell shows half the amount of DNA of some of the other cells. This cell is most likely to be in the G1 phase where the cell has just divided.
Hope this answers the question. Have a nice day.
Bile
Based on the above symptoms, it can be inferred that Gloria lacks bile. Pain in the upper right portion of the abdomen usually corresponds to problems with the liver. The liver produces bile (also known as gall), which is a dark green to yellowish brown fluid that helps most vertebrates with digestion. It increases the absorption of fats and fat-soluble substances such as vitamins A,D,E, and K. It is also necessary for the excretion of bilirubin, which is a byproduct when red blood cells are recycled by the liver.
Bile deficiency can cause the fats in the food to be undigested and these fats end up excreted as part of feces. It can also lead to vitamin deficiency and a gradual build-up of toxins in the liver.
