Answer:
a permeable membrane has a very specific membrane, as in the holes are a lot smaller, meaning only waters, solvents, can pass through (a common example of semi permeable membranes in in the leaves). Whereas a permeable membrane allows solvents and solutes to go through.
Explanation:
Answer:
yes.
Explanation:
because the figure represents a lot more similarities than differences
Answer:
c. They may evolve into two separate species as a result of disruptive selection
Explanation:
Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.
With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.
The chemicals, neurotransmitters are released to carry a nerve impulse which is an electric signal transmitted by the nervous system. This impulse transmitted from one neuron to another. Examples of neurotransmitters are serotonin in which scientists thinks that a low level of this is one of the causes of depression.
