Answer:
Generally, interactions with air, water and living organisms cause the weathering of rocks. Although there are two major types of weathering processes, physical weathering and chemical weathering cannot be separated, and they often work together at different rates to break large rocks into smaller pieces over time.

hope this helps if not sorry :)
A) folded protein happens because this is the most stable conformation that has the most number of internal hydrogen bonds , which result in hydrophobic functional groups being on the outer sides of the protein and causing the hydrophobic effect
"B. purple" is the correct answer.
Answer:
D. Q does not depend on the concentration or partial pressures of reaction components
Answer:
b. Plants grown in typical soil
Explanation:
The experimental control is one that controls for the condition you have changed. The student was changing the salt concentration. But she has to also grow plants in typical conditions to make sure that the plants are able to grow typically. It ensures that any changes made are the result of the changing experimental conditions, not some other factor.
This controls for unforeseen circumstances, such as that none of the plants grow (maybe the seeds were faulty, maybe the weather was poor). It allows you to make conclusions based on what would have happened if you changed nothing. It is vital for ALL scientific experiments!
