Answer:

Thymine

Explanation:

Deoxyribonuceic acid (DNA), is the stored form of genetic material in an organism's cell. It is one of the two types of nucleic acid, made up of nucleotide sequences. A nucleotide is a combination of a five-carbon sugar (Deoxyribose in DNA), phosphate group and nitrogenous base.

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits (Adenine, Thymine, Guanine, and Cytosine). Each of these chains is known as DNA strand. The nitrogenous bases in DNA align with each other in a manner called base pairing.

Complementary base pairing is the phenomenon whereby in DNA, Adenine (A) always hydrogen bonds to Thymine (T), while Guanine (G) bonds to Cytosine (C) i.e. A-T, G-C . In complementary base pairing, a purine (Adenine and Guanine) always binds to a pyrimidine (Cytosine and Thymine). This pairing is responsible for the double-helical structure of the DNA.

Answer:

Condensation is a process in which water vapors changed into liquid state.

Explanation:

Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.

with regard to enzymes, what can be said to the relationship between the substance and the active site?
77julia77 [94]

What is true about microevolution?
iris [78.8K]
Microevolution refers to changes that occur within a single species or group or organisms.  Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type.  For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.
