1. Which type of antibiotic (broad spectrum/narrow spectrum) is more effective in an emergency situation where the pathogen is unknown? Why? A. broad spectrum B. narrow spectrum

A. broad spectrum

Explanation:

An antibiotic is a substance that has the capability to inhibit the growth of or kill bacteria.

A broad spectrum antibiotic has the capability to be inhibit or kill a wide range of bacteria species while a narrow spectrum can only operate within a narrow range of bacteria species.

Hence, in a situation where the the causative organism of the disease (the pathogen) is not known, it is better to use a broad spectrum antibiotic because such antibiotic has a higher chance of eliminating the pathogen.

i believe the answer is a or 1

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
