Answer 1

More than half of the antibiotics we use come from a species of Bacillus filamentous bacteria found in soil.

Step-by-step explanation:

The correct answer to the question is D) Bacillus.

Bacillus is a species of filamentous bacteria found in soil that produces many antibiotics. Antibiotics are natural compounds that are modified to be used as drugs to treat bacterial infections. In fact, more than half of the antibiotics we use come from a species of Bacillus found in soil.

For example, the antibiotic Penicillin is derived from the mold Penicillium notatum. Streptomycin and tetracycline are antibiotics produced by Streptomyces bacteria. These antibiotics and many others are produced by soil bacteria like Bacillus.
