B. Most enzyme-assisted reactions are reversible.
C. Most enzyme-assisted reactions can take place only within a ribosome.

b. Changing one amino acid in the protein hemoglobin causes sickle-cell anemia.
c. Proteins are sensitive to changes in pH.
d. The shape and chemistry of an enzyme's active site determine its function.
A.) High temperatures cause proteins to denature.
The sequence of amino acids, or the primary structure, in a protein determines its shape and function. Changing one amino acid in hemoglobin results in sickle-cell anemia, showing that small alterations in the primary structure can have significant impacts on protein function.
The primary structure of a protein is important in determining its function. It refers to the sequence of amino acids that make up the protein chain. The option that illustrates this relationship is b. Changing one amino acid in the protein hemoglobin causes sickle-cell anemia.
This statement is valid because the amino acid sequence (primary structure) determines the shape the protein takes. In the case of hemoglobin, a single amino acid substitution causes a significant enough alteration in shape to result in the harmful condition of sickle-cell anemia, thus clearly showing the link between primary structure and protein function.

B) molecular homology (comparing DNA)
C) identifying and comparing homologous structures
D) comparative embryology (comparing embryonic development)
Answer: The correct answer is -
B) molecular homology (comparing DNA).
DNA (deoxyribonucleic acid) is considered as the genetic material of living organisms, which is passed from one generation to the next generation that is from parents to their offspring.
By comparing the DNA sequence of two organisms (molecular homology), we can determine whether they are closely related or not.
If two organisms share genetic relatedness that is similarity in their DNA sequence, they are considered to be closely related.
Thus, option B) is the right answer.
