a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

Answer:
b
Explanation:
The single-stranded regions of DNA are protected during replication by <u>single-stranded binding proteins</u>.
<em>The single-stranded binding proteins are a class of protein found in some living organisms. They bind to single-stranded regions of the DNA during the process of replication, recombination, or DNA repair and protect the DNA from being degraded by nuclease enzymes. In addition to protecting the single-stranded DNAs, they also hinder the single-stranded DNA from premature hardening during replication</em>.
The correct option is b.
Answer: Options (a) and (d) are the correct answer.
Explanation:
A catalyst is the substance which helps in increasing the rate of reaction.
Activation energy is the minimum amount of energy required by reactants to start the reaction. On addition of catalyst, the path of reaction changes because the energy barrier gap reduces and hence, the activation energy also decreases.
In the absence of catalyst, we need to increase the temperature so that reaction can occur quickly.
Whereas on addition of catalyst, there is no need to increase the temperature as the catalyst itself is sufficient to increase the rate of reaction. As a result, temperature should be lowered when there is addition of catalyst in the reaction.
Thus, we can conclude that catalysts can save money by essentially lowering the activation energy and temperature required.
Answer:
The chemical reactions in a firework are heat because combustion propels fireworks into the air while oxidization provides the oxygen needed to excite the metal compounds in fireworks.
