The simple question of whether or not viruses are alive, has defied a simple answer because it raises the fundamental issue: What defines life?

Some scientists support the idea that viruses are alive because they contain a nucleic acid.
One key argument against viruses not being alive is that they do not have a cellular structure.
A virus can reproduce asexually via cell division.
Because viruses can spread disease from one organism to another, they are in fact reproducing.
Some scientists believe that a virus responds to its environment when it changes from a dormant to an active form.
Living in a host cell as a parasite qualifies an organism as alive.

A virus can reproduce asexually via cell division because viruses can spread disease from one organism to another.

Explanation:

Reproduction is the characteristics of living organisms.

Virus is a unique microorganisms which have both characteristics of living and non-living things. When they are out of the cell, they are non-living while when are put in the living cell, they start growing and causes infection to the cells.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
