Answer:A) a DNA nucleotide
Explanation: DNA and RNA are nucleic acids. Nucleic acids are made up of monomeric units called nucleotides. Nucleotides are made up of a nitrogenous base, a pentose sugar and a phosphate group. In DNA, the bases found are Adenine, Thymine, Cytosine and Guanine and the pentose sugar found in DNA is deoxyribose, but in RNA the bases found are Adenine, Uracil, Cytosine and Guanine; the pentose sugar found in RNA is ribose.
Answer:
They are in equilibrium
Explanation:
The carrying capacity of a population is the maximum number of individuals a population can cater for or handle at a specific time, often limited by the available resources.
A population that has reached its carrying capacity has a population size that oscillates a little above or below the maximum the environment can support.
<em>Hence, if the birthrate and the death rate of the bison population that has reached its carrying capacity are equal to each other, the rate of immigration and emigration will be at equilibrium with each other.</em>

Explanation:
Although the options are not given, the most probable explanation for the disappearance and reappearance of Lake Jackson is the presence of a sinkhole.
A sinkhole will allow the water to drain down to the water table during the warmer years when the water table is lowered. Then, after the water table is raised due rains, the lake would reappear.
