liberstina [14]

Answer:

Culture/sensitivity

Explanation:

Culture is a kind of test that detects infection-causing bacteria or fungus.

If the microorganism that causes infection grows, the result is positive; if it doesn’t, then the culture is negative.

The sensitivity test tells us what kind of medicine or antibiotic will be suitable to treat the infection.

Hence, the answer is justified.

Polymers are formed via dehydration reactions by molecules. Which of the following best describes a dehydration reaction?
netineya [11]

The correct answer is; "Assembling molecules in either hydroxyl or carboxyl functional groups"

Polymers are formed from monomers either by condensation or by addition of monomers.

A polymer is formed by the joining of one or more monomers. This can happen in either of the following ways;

  • condensation
  • addition

Condensation polymerization involves the loss of a small molecule. When the molecule that is lost is water, we can call it dehydration. Loss of molecules does not occur in addition polymerization.

The two monomer molecules that join to yield the polymer by dehydration must have H and OH moieties in suitable positions for dehydration to occur. A typical example is assembling molecules in either hydroxyl or carboxyl functional groups.
