Answer:
C
Explanation:
It moves across the cell membrane via simple diffusion, a process that requires no energy input and is driven by the difference in concentration levels on each side of the cell membrane.
There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate.
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and <u>guanine -G</u>), a monosaccharide <u>deoxyribose</u>, and a <u>phosphate </u>group. <span>By knowing this, it is easy to choose which molecule of those is the DNA.</span>
Answer:
Enzymes are proteins in composition which are a very essential component of the metabolic reactions in the living organisms.
The properties of enzymes allow the enzymes to be used as a reaction catalyst which increases the speed of the reaction.
The enzymes lower the threshold energy of the chemical reaction and thus increases the rate of reaction.
The enzyme catalyses very complex reactions like a breakdown of complex biomolecules as well as the formation of complex biomolecules.
The active sites are present on the enzymes which bind the substrate molecule and increases the pace of reaction.
Compounds of carbon are defined as chemical substances containing carbon. More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds
Polar molecules have an unequal sharing of electrons, while nonpolar molecules share their electrons equally. water does not have an equal sharing of electrons, thus making it polar
