Answer:
Both the nature of the gene and its environment can influence the mutation rate.
Explanation:
Mutations are caused by environmental factors known as mutagens.
Types of mutagens include
- radiation,
- chemicals, and
- infectious agents.
Answer:
All of the above are true.
Explanation:
The prokaryotic organisms are the unicellular primitive organism which was formed in the primitive time when the conditions on the Earth were harsh.
The prokaryotes developed the metabolism to survive in the extreme conditions and were recognised as the archaebacteria. These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.
The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
Thus, all of the true is correct.
The process of dissolving two organic molecules in a polymer and recombining the water molecules to create new monomers is known as hydrolysis.
<h3>What is hydrolysis?</h3>
The molecule is broken in a hydrolysis reaction involving an ester bond, such as the one between two amino acids in a protein. As a result, the water molecule (H₂O) splits into two groups: one that forms a hydroxyl (OH) group with the remaining hydrogen proton (H+) and another that transforms into a carboxylic acid.
Practically speaking, hydrolysis refers to the process of separating compounds when water is present.
Condensation, which is the process by which two molecules combine to produce one bigger molecule, can also be thought of as the opposite reaction to hydrolysis. The outcome of this reaction is that a water molecule is ejected by the larger molecule.
The three primary hydrolysis processes are
- Acid hydrolysis.
- Base hydrolysis.

I believe the answer is B: Earth's oceans absorb some of the carbon dioxide from the atmosphere.
Galapagos islands are groups of island in the pacific ocean that are known to have a wide range of native animals such as giant tortoise that found no where else on earth. These native animals helped Darwin in the development of the theory of natural significance which attributes to the biological significance of the Galapagos islands. Human species is a threat to the natural wildlife on these islands mainly due to poaching and destruction of natural forests that destroys habitat and also impacts negatively on biological diversity of living organisms.
