For the first question, the age of each strip of rock is needed to determine the rate of seafloor spreading. The answer is B.
For the second question, the answer is A.
Anaerobic respiration is the process that releases the least ATP per molecule of glucose for immediate cell use. Correct answer:D
During this process the glucose is broken down into molecules in the absence of oxygen to produce energy.The energy is produced in form of ATP (Adenosine Triphospahate).
Answer:
Genetic continuity is maintained by the Replication or Synthesis phase and the Mitosis phase of the Cell cycle.
Explanation:
- The Cell Cycle can be divided into the following phases,
- G0- Interphase.
- G1 - Growth phase.
- S - Replication or Synthesis phase.
- G2 - Second Growth phase.
- M - Mitosis.
- Of all the above phases, in the S phase the replication or doubling of the genetic material, that is, the DNA, occurs for equally distributing the genetic material to both the daughter cells.
- The M or the Mitosis phase is also essential to ensure that the distribution of the genetic material occurs accurately among the daughter cells.
- Hence, a genetic continuity is maintained across the generations of the cells.
