Solar power/energy or hydroelectric plants
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
Algae doesnt classify as a plant because they don’t necessarily have roots, stems, or leaves
Guard cells close up to prevent water loss. These guard
cells will automatically open up if there is a need of water to go out of the
cell. An open stomate allows water to leave through transpiration, guard cells
control the opening and closing of a stomata, stomates will close to reduce
water loss and By opening and closing the stomata on the underside of the
leaves.

They occur when the Sun reaches its highest or lowest point in the sky.
