Nitrogen fixation, N2 --> NH3+, is not something that plants to by themselves but some plants have bacteria that does this. I believe that pea plants have these, but I'm not 100% sure.
RNA polymerase is guided to the correct place.
Isotonic solutions is the term used when the concentrations of solutes inside and outside a cell are in equilibrium.
Explanation:
The isotonic solution is one which have same osmotic pressure on either side of the semi-permeable membrane.
In the isotonic solution there will be free movement of only water molecules and not solutes.
isotonic solution is the solution when two solutions have equal solute concentration.
The concentration of the solution will be in equilibrium.
Answer: Timber industry, paper industry, furniture industry.
Answer:
There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).
Explanation:
This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.
However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.
