It increases.

It decreases.

It decreases initially for a short time and then returns to the original value.

10 mg

4 μg

10 μg

they cannot assimilate ordinary carbohydrates.

they can tolerate lower, but not higher than normal blood sugar levels.

they require less carbohydrate than healthy individuals.

Mutation created a terminator codon.

The gene was not transcribed.

The organism could not make amino acids.

Mutation broke the protein.
