OK so a cell wall protects just like the walls of a house. Vacuoles are extremely important in providing structural support in a cell, so like beams for supporting structures. And the nucleus is the command center as it consists of many structured elements that allow it to perform its functions.

Answer: isotopes
Explanation: same element containing equal numbers of protons but different numbers of neutrons in nuclei. Differ in atomic mass but not in chemical properties.- Google definition of isotope.
Answer: planting vegetation terracing, retaining walls
Explanation:
Mass wasting or mass movement is a natural process of movement of materials such as soil, boulders, stones and others down the slope under the influence of gravity. This is responsible for mudslides and landslides.
The planting vegetation terracing will help in prevention of mass wasting as the plant roots will hold the soil. It will be beneficial if the vegetation is grown on the steps that is terracing.
The retention of walls will prevent the movement of the materials down the slope. Thus will stabilize and control the mass wasting.
