Which substances are responsible for accelerating chemical reactions in cells?
amino acids
enzymes
nucleic acids
lipids

Correct B). Enzymes

The enzymes are the biological catalyst that reduces the activation energy of the chemical reaction and increase the rate of the reaction without being used up in the reaction. The molecules on which the enzymes act are called as substrates and it converts the substrate into different molecules called as products.

Hence, the correct answer would be ''enzymes''.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
