yulyashka [42]

Answer:

B. The mutation results in a new, dominant allele

C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.

D. The mutation occurs in a codon and alters the function of the final protein

Explanation:

All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.

Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.

This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.

Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.

bija089 [108]

Answer:

The correct option is d. it causes exchange diffusion

Explanation:

Amphetamines are synthetic substances with a stimulating effect. Their action lies mainly in increasing synaptic levels of monoamines by various mechanisms, including diffusion exchange through membrane transporters. Amphetamine increases extracellular concentrations of serotonin by displacing the neurotransmitter from its specific presynaptic transporter. When amphetamine binds to serotonin transporters, on the one hand it prevents it from entering the terminal and on the other it reverses the recapture mechanism so that serotonin leaves the synaptic space.
