Answer:
- Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface
- Terrestrial ecosystem.
- Forest ecosystem.
- Grassland ecosystem.
- Desert ecosystem.
- Tundra ecosystem.
- Freshwater ecosystem.
- Marine ecosystem.
- Remove and store waste produced during autophagy (when part of the cell is broken down due to age or damage)
- Remove and store harmful foreign products so they don't damage the cell.
- Store water.
- Store nutrients such as lipids, proteins, and carbohydrates.

- The different types of the ecosystem include:
- Terrestrial ecosystem.
- Forest ecosystem.
- Grassland ecosystem.
- Desert ecosystem.
- Tundra ecosystem.
- Freshwater ecosystem.
- Marine ecosystem.
- Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
