Questions

We know that, solids have definite shapes and definite volumes, whereas liquids have definite volumes but indefinite shapes and coming to gases it has indefinite volumes and indefinite shapes.

Hence, only in solids, the forces of attraction limit the motion of particles.

Photosynthesis takes place inside plant cells in small things called chloroplasts.

Chloroplasts contain a green substance called chlorophyll and this absorbs the light energy needed to make photosynthesis happen.

Lipids are soluble in solvents of low polarity, which simply means that lipids are soluble in nonpolar solvents. This solubility property is a result of the large nonpolar regions that are indicative of the lipid molecule.

Goosebumps are caused by the contraction of the tiny muscles attached to hair follicles. These muscles are arrectores pilorum muscles.
