What are the answer choices?
Answer: d. These filaments help the cell to withstand mechanical stress.
Explanation:
Intermediate filaments are the rope like fibers. These filaments form an extensive network ranging from the nucleus to the plasma membrane thus these filaments entirely cover the cytoplasma of the cell. These are developed from the cytoskeletal proteins. They have a diameter that is intermediate between thick and thin myofibrils. The diameter of the myofibril is in between 10 to 12 nm. They stabilize the nucleus. The main function of the intermediate filaments is to provide mechanical strength to the cells that will help them to withstand stress during stretching, elongation and changing shape.
Answer:
The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth.

The current greatest threat to agricultural sustainability is A. erosion.
Given that erosion is affecting the soil by breaking it apart, and given that soil is rather important for agriculture, if something happens to it, the agriculture of that particular area will be affected as well. Although air quality and water pollution are definitely important, they are not as dangerous as erosion.
3. I would kinda say 1 but the soil wouldn't be more polluted if there wasn't as much water in the stream, to begin with.
