Ascientist discovers that a soil bacterium he has been studying produces an antimic robial that kills gramnegative bacteria. she isolates and purifies the anti microbial compound, then chemically converts a chemical side chain to a hydroxyl group. when she tests the anti microbial properties of this new version, she finds that this antimicrobial drug can now also kill gram-positive bacteria. thenew anti microbial drug with broad-spectru mactivity is considere dto be which of the following? a. resistantb. semisyntheticc. syntheticd. natural

The correct answer will be option-B (Semi-synthetic)

Explanation:

Chemical drugs can be synthesized through many ways on the basis of which they can be categorized:

1. Natural Drug: The drug prepared from the natural extracts.

2. Synthetic Drug: The drug is synthesized by chemical reactions.

3. Semi-synthetic Drug: The drug which is neither completely natural nor synthetic that is they are prepared from the natural extracts by modifying them.

Since in the given question, the drug was prepared by the converting side chain to the hydroxyl group of the antimicrobial drug therefore it is considered as the semi-synthetic drug and Option-B is the correct answer.

eukarya because is is like alche and b is bacteria and d is animals

explanation:

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
