vladimir1956 [14]

Answer:

Sí, ya que su función es matarlas o impedir que aumente el número de estas.

Explanation:

Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.

Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo.

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.
