Clostridium botulinum is a bacterium that produces botulinum toxin that inhibits the release of acetylcholine. Which description best fits how muscle cells will respond to a lack of acetylcholine?

muscle cells will  become paralyzed when there is a lack of acetylcholine

Explanation:

Based on the information provided within the question it can be said that in this scenario the muscle cells will  become paralyzed when there is a lack of acetylcholine. That is because the Acetylcholine (ACh) is an organic chemical within the brain and body that acts as a neurotransmitter to send signals from the brain to the muscle cells. Without those signals the muscle cells cannot respond and are therefore paralyzed.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

thats not a question
