Answer:
A rapidly changing environment
Explanation:
The sexual reproduction is more advantageous to organism to survive in the harsh conditions due to the changes in the sequence of nucleotides of the genes which became a characteristic feature of the sexual mode of reproduction.
This process of changes in the sequence is known as recombination. The sexual mode or reproduction evolved in the last common ancestors of eukaryotes but it is known to occur in the prokaryotes also as they reproduce by conjugation, transformation and transduction.
The sexual mode of reproduction was evolved in the organism as a result of the change in the environment to survive and thrive in the environment.
Gene pool is the variety and available genes in a specific population of a species .
All of the above.
<h3>What are sulfur oxidizing bacteria?</h3>
Any of a wide range of microorganisms that can metabolize sulfur and its components and are significant in nature's sulfur cycle are known as sulfur bacteria. Hydrogen sulfide (H2S), sulfur, and thiosulfate are a few of the typical sulfur compounds that are used by these bacteria as a source of energy. Sulfate is the end result of the oxidation of sulfur.
In deep earth deposits, <em>Thiobacillus</em>, which is common in both marine and terrestrial settings, produces sulfuric acid, which dissolves metals in mines but also corrodes concrete and steel. It also oxidizes sulfur, generating sulfates that are helpful to plants.
I understand the question you are looking for is this:
In seawater, sulfate is the most common anion after chloride. Which of the following is correct with respect to the use of sulfate by some bacterial groups?
- Oxidized sulfur-containing molecules have redox potentials lower than those of the nitrogen series.
- Oxidized sulfur molecules such as sulfate and sulfite serve as electron acceptors.
- Sulfate and sulfite can receive electrons from hydrocarbons.
- Sulfate-reducing archaea and bacteria are widespread in the ocean.
- All of the above.
