Answer: Base pairs are formed when adenine forms a hydrogen bond with thymine, or cytosine forms a hydrogen bond with guanine. The second part of a nucleotide is the phosphate, which differentiates the nucleotide molecule from a nucleoside molecule.
Explanation:
Answer:
A)
global temperature increasing as CO2 concentration increases
Explanation:
Global warming is the progressive increase in the temperature of the earth's atmosphere. Global warming is caused by an increase in the concentration of greenhouse gases e.g CO2, chlorofluorocarbons etc. These greenhouse gases, in which carbondioxide is an important example, are capable of trapping heat in order to keep the earth warm.
Howeever, as the concentration of CO2 and other greenhouse gases increase in the atmosphere, the earth's atmospheric temperature also increases above normal, causing Global warming.
In this case, the science teacher's graph will show that global temperature is increasing as CO2 concentration increases.

The answer is microscopic life appeared on Earth before flowering plants. This is because according to the label on the second box, microscopic life appeared 4.0 to 3.5 billion years ago, and this is way before the date 250 to 120 millions years ago indicated on the label on the sixth box the flowering plants appeared on Earth.
