Your answer is A: these two organisms have the same amino acid sequences, which suggests common ancestry
Nitric oxide accomplishes this by elevating cGMP levels.
- NO is a distinctive message. It is a gas, although it does dissolve in an aqueous solution.
- It is a free radical with an unshared electron, which will react with thiol groups on proteins to form new complexes.
- Unlike other second messengers, NO doesn't need energy to move inside and outside of cells. It can go where it wants, but it does not travel far because it is a reactive free radical.
- NO acts within the cell that produces it as a second messenger. It operates as a paracrine molecule able to travel 10–20 cell diameters to affect the biology in surrounding cells. It can form complexes with proteins like hemoglobin, glutathione, and other proteins and then separate from those complexes.
Therefore, increasing cGMP levels is necessary.

<span>DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a template for replication. Primers bind to the DNA and DNA polymerases add new nucleotide sequences in the 5′ to 3′ direction. This addition is continuous in the leading strand and fragmented in the lagging strand. Once elongation of the DNA strands is complete, the strands are checked for errors, repairs are made and telomere sequences are added to the ends of the DNA.</span>
Answer:
Microbes are vital to control biogeochemical cycling of the elements essential for life.
Explanation:
Microbes are vital to control biogeochemical cycling of the elements essential for life. In a biogeochemical cycle, nutrients move through the ecosystem, allowing many forms of matter being passed from one organism in one part of the biosphere, to another organism in another part of the biosphere (microorganisms can circulate through biotic or abiotic ecosystems), in this way, ensuring the supply of essential nutrients for plant crop and growth, the degradation of organic matter, the maintenance of soil quality/structure and the carbon losses to the atmosphere. In conclusion, without microbiological activity, nutrients cycling and other functions in the ecosystem would be impossible.
