dna replication involves unwinding two strands of parent dna, copying each strand to synthesize complementary strands, and releasing the parent and daughter dna. which of the following accurately describes this process?
this is an anabolic process.
this is a catabolic process.
this is both anabolic and catabolic.
this is a metabolic process but is neither anabolic nor catabolic.
none of these answer choices are correct.
question 3

consider a pendulum swinging. which type(s) of energy is/are associated with the pendulum in the following instances: i. the moment at which it completes one cycle, just before it begins to fall back towards the other end, ii. the moment that it is in the middle between the two ends, and iii. just before it reaches the end of one cycle (just before instant i.).
i. potential and kinetic, ii. potential and kinetic, iii. kinetic
i. potential, ii. potential and kinetic, iii. potential and kinetic
i. potential, ii. kinetic, iii. potential and kinetic
i. potential and kinetic, ii. kinetic iii. kinetic

Explanation:

• Question 1: Glucose stores energy long - term through its chemical bonds. ATP is used short - term for cellular work as it can quickly release energy by breaking its phosphate bonds.
• Question 2: DNA replication involves building new DNA strands (anabolism) from nucleotides using the energy and building blocks available in the cell.
• Question 3:
• i. At the end of a cycle just before falling, the pendulum is at its maximum height, so it has only potential energy.
• ii. In the middle between the two ends, it is at its lowest height and has maximum speed, so it has only kinetic energy.
• iii. Just before reaching the end of a cycle, it has both height (potential energy) and some speed (kinetic energy).

Answer:

• Question 1: glucose : ATP
• Question 2: This is an anabolic process.
• Question 3: i. potential, ii. kinetic, iii. potential and kinetic
