Salt molecules are much smaller than starch molecules and can pass through more easily. ... Thus, they are quite large molecules in contrast to the relatively small salt molecules. The smaller salt molecules pass through the membrane easily, but the larger starch molecules cannot pass through the membrane.
<span>The answer could be allopatric or sympatric speciation
depending on the cause of speciation. A population living in the same habitat
could be separated by a physical barrier hence restricting gene flow in the population.
On the other hand, sympatric speciation refers to the formation of different species
from a population that is in the same habitat and geographical area without any
physical separation. This could be due to differences in mating tendencies of individuals
in the population </span>

Answer:
Explanation:
Dilute solutions are prepared so as to allow a significant amount of light to pass through the solution and be measured by the recorder. Opaque solution are also diluted so light can pass through and be recorded. Similarly other substances which have very large absorption have to be diluted so that significant amount of light could reach detector.
