Answer:
C. Polar
Explanation:
The city Q is most likely to be present in the polar region. The polar climate regions do not have any warm summers. The average temperature in a polar region is predicted to be less than 10 °C. About 20% of the earth is known to have the polar climate. Annually, less than 25 cm rain or precipitation is noted in the polar region. Hence, the city Q is most likely to be located in the Polar region.

Answer:
d. Under normal circumstances, each chromosome contains precisely one gene.
Explanation:
The gene is a segment of a DNA molecule, responsible for genetically inherited traits. Each gene consists of a specific DNA sequence that contains a code (instructions) to produce a protein that performs a specific function in the body. Each human cell has about 25,000 genes.
The genes are located within the chromosomes. A chromosome can house thousands of genes, it is not normal for a chromosome to house a gene or a few units. Thus, if a cell contains 46 chromosomes, that cell has an incalculable number of genes.
