compose a four-sentence paragraph that Infers why humans would not be able to repair and grow muscle without bacteria
erastova [34]

Vitamin K is found in bacteria like E. Coli and aids in blood clotting. Vitamin K aids the body's absorption of mineral calcium, allowing for proper muscle growth and repair.

<h3>What is E. coli?</h3>

E. coli is a Gram-negative, facultative anaerobic, rod-shaped coliform bacterium of the genus Escherichia that is frequently found in the lower intestine of warm-blooded organisms.

Vitamin K, which is found in bacteria such as E. Coli, aids in clot formation.

Vitamin K promotes mineral calcium absorption in the body, allowing for proper muscle repair and growth.

Thus, due to this reason, humans would not be able to repair and grow muscle without bacteria.
