Answer:
C. Producers
Explanation:
Producers (plants) can turn the sun's energy into usable energy by photosynthesis. They are at the bottom of the food chain; all of our energy comes from them. :)
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.
