Answer:
The original sunlight is a mixture of colors.
Explanation:
- The sunlight is perceived by our eyes as white because it is a mixture of seven colors - violet, indigo, blue, green, yellow, orange, and red.
- When these colors of light separate from each other and are differentially absorbed and reflected, we can see the different objects in different colors.
- The reason for the differential absorption and reflection is that the different colors have different wavelengths.
- Therefore, the barn looks red because the red light is reflected by the barn and other lights are absorbed, however, the original color of the sunlight is white.

B. Cells
Explanation:
The plasma membrane is one of the essential structural and functional components of all the cells. It maintains the cell's interior and regulates the entry and exit of substances into and out of the cells. Both prokaryotic and eukaryotic cells have a plasma membrane.
Plasma membrane forms the outer most covering of an animal cell. Plant cells and bacterial cells have a cell wall outside the plasma membrane. Irrespective of the cell type, the plasma membrane is made up of a bilayer of phospholipids with a hydrophobic core. Several proteins are embedded in the lipid bilayer.
Biomechanical mechanisms, habitat for plants and animals, participates in cycling of all materials used by living things.
