Answer:
The greatest of environmental factors on phenotype is on phenotypic plasticity, phenotypes that may change due to changes in the environment; ex: snowshoe hare have brown-colored fur in summer/spring and white fur in winter. Environmental factors may affect gene expression which may result in normal/abnormal phenotypic changes.
Explanation:
Carbohydrates are not important as a stimulus in the gastric phase of gastric secretion, whereas distension, peptides, and low acidity are.
The answer is invasive species.
Invasive species are species that are not native to specific ecosystem,
but they have a capability to spread widely through the ecosystem, This way
they can threaten native species of the ecosystem or cause
environmental harm.
<span>After being introduced into the Black Sea, they greatly affect local
ecosystem. In the new area, they have no natural predators and are able to
spread. If they spread beyond the area they are introduced, they
become invasive species which can overgrow native biotopes and are
a great threat to the local biodiversity. This could lead to the extinction
of some native species.</span>
