I believe the answer is the nucleus
Answer:
D) lowering the energy for activation.
Explanation:
Just like chemical catalysts that accelerate the rate of chemical reactions, enzymes are biological catalysts that accelerate the rate of biochemical reactions.
Majorly, a catalyst works by lowering the activation energy required for a specific reaction. The lower the activation energy for a reaction, the faster the rate of that particular reaction.
Hence, an enzyme accelerates the rate of reaction by lowering activation energy of the reaction.
Prokaryotic cells lack a nucleus.
Answer:
Because there is already presence of soil and nutrients in secondary succession
Explanation:
Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.
- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.
This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.
