Innate immunity________.
labwork [276]

Answer:

The answer is A.

Explanation:

Since only 1 of the options is wrong, i assume you are looking for that one.

Two types of immunity systems, innate immunity and adaptive immunity. Adaptive immunity is formed when it is exposed to a harmful substance, vaccines for example create adaptive immunity.

Innate immunity is present at birth which consists our skin protects us physically, chemical substances in our blood that protect us from bacteria and infections and also our blood cells such as T cells.

Since innate immunity forms one of the first lines of defense in our immune system and is the first to respond to a threat in a few hours down to as little as minutes, it is not slower than adaptive immunity in its response to infections and pathogens.

I hope this answer helps.
