The answer would be: Isotretinoin
Isotretinoin is vitamin A derivative that has an effect on the skin. It will reduce sebum formation and secretion, so it will reduce the risk to form another acne. The anti-inflammatory will effect will reduce acne swelling and pain. The anti keratolytic effect will normalize the skin growth.
Answer:
c) microevolution
Explanation:
Microevolution is the change in allelic frequencies within a population over time.
If natural selection favored birds with beaks and small bodies, that means that the frequency of that phenotype (beak and small body) increased while the frequency of birds with body and large beaks decreased.
In this example we see that in the Darwin's finches population, the allelic frequencies - reflected in the phenotype - changed over time as a consequence of the drought.
When a person meets a hot object without thinking about it, the heat stimulates temperature and danger receptors in the skin, resulting in a sensory impulse that passes to the central nervous system. After that, the sensory neuron forms synapses with interneurons, which then connect to motor neurons.
Functions. this is the very idea behind differentiation.<span />
The behavior helps the animal because its what helps them to survive , mate , and even help reduce societal problems
