Answer:a). mutated DNA strand

Explanation: Mutation is a permanent alteration or change in the nucleotide sequence of a DNA. When one or more wrong nucleotides are added to a growing strand of DNA during replication, the base pairs involved are said to be mismatched. These mismatches result in a mutated DNA strand instead of a complementary DNA strand. Normally, new DNA strands are complementary to the template strand in the sense that they are not the same in base composition and sequence rather, wherever adenine is found in the template strand, thymine occurs in the new strand and wherever guanine occurs in the template strand, cytosine occurs in the new strand.

Lelechka [254]

Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.

Explanation:

In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.
