Why is it easy for a virus to mutate?

Biology
1 answer:
drek231 [11]3 years ago
6 0

Answer:

Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.

The purpose of the digestive system is to break down food into simple molecules that the _______ of the body can use.
erma4kov [3.2K]


The purpose of the digestive system is to break down food into simple molecules that the cells of the body can use. 

Food is broken down  into its simplest units called monomers. Proteins are broken down into amino acids, fats are broken down into fatty acids and glycerol while carbohydrates are broken down into glucose units.

Glucose is taken in by the cells of the body and through the process of cellular respiration  is used to produce the ATP, the form of energy that cells use. Cellular respiration is the process by which cells use glucose to produce energy to power their functions.
