Answer:
True
Explanation:
This is true because any element or compound with hydrocarbons tend to be non-polar.
Carbohydrates are built from the building blocks of Oxygen, Hydrogen, and Nitrogen.
The correct answer is absolute threshold.
Absolute threshold is a neurobiological term referring to the lowest level of a stimulus that a person is able to detect. The stimulus can either be touch, sound, taste or light.
Regarding taste, the absolute threshold of taste is the lowest concentration of a certain compound which can be detected by the human sense of taste.
Correct answer: D). Deletion
Tay-Sachs disease is an autosomal hereditary disease that is known to affect the central nervous system. It results from the mutation caused in the gene that encodes for the beta-hexosaminidase enzyme. It is a lysosomal enzyme that is composed of the beta and alpha polypeptides.
It is caused when both the parents are a carrier, it occurs when a baby is born in absence of hexosaminidase. It affects the nervous system and can change the physical appearance after a few months of the birth.
Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
