Answer:

The correct answer is option A. "Some animals exhibit similar proteins".

Explanation:

There is plenty of evidence that support the theory that life changes over time, and that living species have different common ancestors. Regarding the evidence provided by analysis of biological chemicals, the fact that some animals exhibit similar proteins supports this theory. This type of proteins are called homologous proteins, and is possible to construct phylogenetic trees based on sequence and structure similarities among them.

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.
