According to the theories of aging, Dr Miller is trying to explain the peripheral slowing hypothesis.
<h3>What is the peripheral slowing hypothesis?</h3>
It states that people age because their nervous system's processing accumulates damage from the wear and tear of everyday life, and erodes the normal biochemical activities that occur in cells, tissues, and organs.
The nerves of the brain wear out naturally, directly affecting the mitochondria that provide energy for all cellular activities.
Therefore, we can conclude that Dr Miller is trying to explain the peripheral slowing hypothesis suggests that overall processing speed declines in the peripheral nervous system.

Answer:
If a cell more than doubled its size before dividing, the daughter cells would be larger than the original cell. If this happened with each generation, cells would quickly become too large to live. Similarly, if a cell did not double its size before dividing, the daughter cells would be smaller than the original cell.

<u>Answer:</u>
<em>It is not true to say that common ancestors occurs only within a single species rather two species with similar traits might have a common ancestor. </em>
<u>Explanation:</u>
If the ancestor is same for both the species then it is said that both the species are closely related and share common ancestor with similar evolutionary relationship.
Phylogenetic tree are drawn and studies are done to understand the ancestor of a species. The evolution has occurred from the ancestor to the new species formed.
DDT was used to control the malaria-causing mosquitoes. DDT killed them but accumulated in the soil also, through which entered animals and humans via food. There, it gets stored in the fat tissue and is very difficult to breakdown. The predator animals, feeding upon smaller animals, got DDT in their bodies from the smaller animals and DDT thus, magnified to the top level of the food chain. The government realized this and banned DDT.
