An Intron is a part of DNA that does not code for a functional protein
ATP or Adenosine Triphosphate is
the energy that the cells use to make the body perform properly. Carbohydrate
is the preferred nutrient for ATP production in the mitochondria of the cell
because it can be easily broken down. When absorbed by the body, carbohydrates
automatically turn into glucose and glycogen.

Glucose, as the by-product of
carbohydrates, readily provides a supply of energy to the body as it circulates
with the blood. Too much glucose in the blood will make the blood sticky and
will have a hard time to flow in the blood vessels.
Glycogen on the other hand,
is the back-up energy source of the body when glucose is no longer available.
It is stored in the muscles and liver. It can readily turn again into glucose
when the body thinks it needs it.</span>
Answer:
Option (B) Ethylene gas is a chemical signal through which ripening fruits trigger the ripening process in other fruits.
Explanation:
The ethylene hormone triggers the ripening process of fruit. However, in order to slow down the ripening process the action of ethylene is to be blocked. All fruits are capable to produce ethylene up to a certain level after which they start ripening. There are some classes of fruits that respond to the external ethylene such as apple, mango, tomato etc.
Hence, option B is correct
Answer:
Reproductive isolation, as well as taxonomic and genetic differences, can be used to discover and classify new species
Explanation:
According to the biological concept of species, "the species can be recognized to be reproductively isolated by morphological, behaviors and physiological processes that prevent interbreeding with other groups". These differences can include taxonomic changes and the lack of homology between conserved genes, which enable us to discern that two individuals belong to different species. In genetics, for example, the mitochondrial gene Cytochrome Oxidase I (COI) is widely used to differentiate between species because it is evolutionarily conserved, thereby important sequence differences may indicate that two individuals belong to different (even cryptic) species.
