Answer:
Amino acid are the monomers of protein.
Many amino acids link together by peptide bonds, forming proteins.
They are less threatened because they are more adapted to their environment therefore will survive drastic environmental change. This is because they are more diverse: they have evolved more.
Answer:
The correct answer is A) Replicability.
Explanation:
The principle of replicability states that the results obtained by a researcher, in certain investigation work, have to be the same for other researchers who are following the same steps. If the experiment cannot replicate under the same conditions, then it's not valid to the scientific community and therefore cannot be published.
Answer:
C. They produce and use adenosine triphosphate (ATP).
Explanation:
ATP is the energy currency for the cells of all living beings. It is produced by aerobic or anaerobic respiration in both prokaryotes and eukaryotes. Complete or incomplete oxidation of nutrients obtains ATP. ATP is used by cells to perform all the vital functions. ATP synthesis occurs when phosphate is added to ADP during substrate-level phosphorylation or oxidative phosphorylation. Hydrolysis of ATP includes the release of terminal phosphate and lots of energy which in turn is used by cells.
