In a chemical reaction, a reactant bonds to an enzyme at a region known as the Active Site.
Answer:
<h2>A</h2>
Explanation:
1. Nucleus is a ball like structure which is found in the center of the cell only in eukaryotic cell, true nucleus is absent in prokaryotes.
2. Nucleus contains nucleic acid and is have double membrane which contain pores though which transport of molecules occurs.
3. DNA replication , transcription and RNA splicing occur in the nucleus.
Out of the choices given, the water rises and falls with precipitation. The water table is the level below where the ground gets saturated with water. The correct answer is B.
7. The correct answer is photosynthesis.
Autotrophs are organisms which produce food for themselves-from simple to complex molecules. In the case of photosynthesis, producers (plants or some algae) use the light energy to produce complex organic compounds (carbohydrates, fats, and proteins).
8. The correct answer is primary consumers.
Since the pioneer species are usually autotrophs because there is no other source of energy except light energy in the early stages of succession (after the eruption). Most likely, the primary consumer will appear next because they feed upon producers.
9. The correct answer is: they are different populations of fish.
Those two different kinds of fish have unique adaptations that enable them to survive and live in distinct environments. It is most likely that molecular changes underlie adaptation and speciation of those fishes.
Answer:
Saving wood
Explanation:
It takes less water to break down waste paper than it does to break down wood. If paper recycling is used to the full potential, wood is only needed once to produce 5 cycles of paper which also means saving waste from landfill 5 times.
