Answer:
Glyceraldehyde-3-Phosphate Dehydrogenase
Explanation:
Glyceraldehyde-3-Phosphate Dehydrogenase is responsible for the formation of 1,3-bisphosphoglycerate, which is then catalyzed to yield phosphoenolpyruvate by pyruvate kinase.
Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
The answer would be none of the above as nails, follicles, and glands are known as appendages
