Answer: The correct answer is-
an agent that causes a mutation in DNA.
Mutagen is an agent or a substance that causes permanent change in the genetic material of living organisms ( DNA, deoxyribonucleic acid). This process is called mutation.
A mutagen can be a chemical, physical or biological agent that causes mutation in the DNA.
Example- Physical agents such as -
- Ionizing radiations like alpha particles, gamma rays, X-rays that brings break in the DNA and cause other damages.
- Ultraviolet radiations that creates pyrimidine dimers ( T=T) and causes replication errors if damage is not repaired.
The animal that takes energy from more than one trophic level is eagle due to eating of many organisms.
<h3>Which animal gets energy in more than one trophic level?</h3>
The eagle is the animal that takes energy from more than one trophic level in the given food web because in this food web eagle feeds on animals such as rabbit, reptile such as snake and bird such as owls.
So we can conclude that the animal that takes energy from more than one trophic level is eagle.

<span>A seatbelt should be fastened so as to run diagonally across the chest and to fit low and tight across the waist. This ensures that, during the rapid deceleration experienced during a crash, the seatbelt will perform the intended function, that is, to keep the passenger in place within the vehicle.</span>
Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
