Broad-spectrum drugs target a wide variety of bacterial pathogens. even when the broad-spectrum drug is capable of killing a target pathogen, it may not be the best treatment.
which statement best explains why a broad spectrum drug might be an undesirable treatment choice?
group of answer choices

broad-spectrum antimicrobials only work if they are used shortly after the infection begins.

broad-spectrum antimicrobials are usually toxic to the host cells.

broad-spectrum antimicrobials may kill much of the normal microbiota.

broad-spectrum antimicrobials may stimulate excess growth of the normal microbiota.

broad-spectrum antimicrobials are not able to kill bacteria that are in their log phase of growth.

The correct option is C. Broad-spectrum antimicrobials may kill much of the normal microbiota.

Explanation:

Broad-spectrum antimicrobials are drugs which kill a wide range of microbes. These drugs are often used when a disease-causing microbe cannot be identified. The drawback of using such kind of drugs is hat it may severely harm the normal microbiota causing illnesses like diarrhoea.

On the contrary, narrow-spectrum drugs are the drugs used against a specific strain of microbe. They are more effective to kill a single type of microbe.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
