Biology
1 answer:
melamori03 [73]3 years ago
8 0

Answer:

C

Explanation:

in a semi-permeable membrane, very specific amounts of materials are allowed through. This is particularly helpful in the human body because the body can then create "charge differences" between ions. In these charge differences, neurons can fire and pretty much all movement in your body is achieved because of these membranes. They are also called selective membranes

Viruses do not possess all the characteristics of life. Identify those characterustics that viruses display and those they don't
seraphim [82]
The main aspect of viruses that causes controversy over it being classified as living is its manner of reproduction.

Viruses do reproduce, like a living organism. However, they cannot do so without a host cell, so they are unable to reproduce on their own, which means that they are not living.

Hope this helps!
