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.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
