Answer:
1. Air warms, becomes less dense, it rises
2. Air cools down, increases density (becomes denser), it sinks
Answer:
B. Release body heat
Explanation:
Jackrabbits live in deserts, and therefore must release excess body heat through the surface area of their ears to avoid quickly overheating and dying.
Two organisms have the same phenotype but different genotypes when One organism is purebred dominant, and the other organism is heterozygous. So, the correct option is B.
<h3>What do you mean by Genotype?</h3>
Genotype may be defined as the ultimate combination of those alleles which are selected for specific studies.
When an allele is dominant over others, its purebred dominant and heterozygous (hybrid) may have different genotypes but the same phenotype.
Therefore, the correct option for this question is B.

Answer:
Yes, your answer, nitrogen, is correct (the most appropriate option). However, oxygen is also a correct option.
Explanation:
Nitrogen exists on its own as a diatomic gas. However, it exists as organic nitrogen in nucleic acids such as DNA and RNA (as part of their nitrogenous bases) and in the amino (--
) group of amino acids.
Do note that a case can also be made for oxygen as a right option: like nitrogen, it exists as a diatomic gas and can be found in both nucleic acids and in the carboxylic group of amino acids.
Sulfur is not an appropriate option as nitrogenous bases (and nucleic acids) to the best of my knowledge do not contain sulphur although some amino acids like cysteine do.
Carbon is not also an appropriate option because elemental carbon does not exist in gaseous form even though it can be found in both nucleic acids and amino acids.
Answer: Since the industrial revolution, human activities have also resulted in an increase in natural greenhouse gases, especially carbon dioxide. An increase in these gases in the atmosphere enhances the atmosphere's ability to trap heat, which leads to an increase in the average surface temperature of the Earth.
