The answer is; B
Mutations change the order of nucleotide and therefore affects codons that code for proteins. A different protein is thus produced from the wild type hence creating variations. Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.
Answer:
Water, organic biological molecules, sodium chloride, glucose.
Explanation:
A compound is anything composed of two or more separate elements.
- O2 and H2 are a singular elements, and a chain of carbon atoms is multiple of the same element, so these are not considered compounds.
- Sodium chloride is sodium and chlorine, and water is oxygen and hydrogen. Glucose is a compound of sugar, and organic biological (or biomolecules) are made up of carbon and hydrogen, so these are all considered compounds

Answer:
TRUE
Explanation:
There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.
The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.
Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.
Thus, the above-given statement is true.
