The correct answer is option B, hydrogen.
The majority of the atmospheric gases are found in the sea water solution. In supplementation to oxygen and nitrogen, the most profusely found gas in the atmosphere, that is, carbon dioxide is found in the ample concentrations in the ocean waters.
However, hydrogen is not present, and if found it is found in minute concentration. Of the gases, nitrogen is the most abundant gas found in seawater, while oxygen is the second most abundant, and carbon dioxide is the most soluble gas, and one of the various constituents, which influences the pH balance of the ocean.
1) The answer is <span>bluegreen algae
</span>
Bluegreen algae or cyanobacteria <span>are thought to have started life on earth because they converted the atmosphere that didn't have a lot of oxygen, into an atosphere with enough oxygen to exist life. That </span>oxygen was a product of their photosynthesis.
2) The answer is lightning.
<span>By Primordial Soup Theory, life began as a result of the combination of chemicals from the atmosphere and lighning (a form of energy) to make amino acids. Aminoacids are necessary to build proteins, and proteins are necessary for all the organisms.</span>
The sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes each having n number of chromosomes.
<h3>What are diploid organisms?</h3>
Diploid organisms are organisms having two copies of each chromosome or 2n number of chromosomes
Diploid organisms undergo meiosis to produce haploid cells having n chromosomes.
Two haploid cells from each parent combine to produce offspring with 2n number of chromosomes.
Therefore, the sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes with n number of chromosomes.
