Answer: The structure and curvature of the Earth results in beams of sunlight glancing off the equator and reaching other areas of the Earth. This means that the areas at the equator receive more energy as the sun's rays hit them directly. :)
All matter is composed of protons, neutrons, and electrons. Therefore the answer is sodium.
The provided question is incomplete as the options are not given, however on the general knowledge the answer is given:
Answer:
The correct answer is - cytoskeleton, plant cell wall, plasma membrane.
Explanation:
The cytoskeleton is the component that helps in the provided different functions in an organism such as maintaining cell shape, cell signaling by filament systems regulation, and facilitate movement and support.
The plant cell wall also helps in providing the cell to maintain its shape and offers the structural support and cell to cell communication is done by the plasmodesmata that also helps in the movement of the small molecules to transfer from one to another.
The plasma membrane has specific receptors present on them that help in the cell signaling, plasma membrane is semi-permeable and so are able to transport the molecules selectively or with the help of transport protein.
Thus, the correct answer is - cytoskeleton, plant cell wall, plasma membrane.
