Eukaryotes have the ability to switch gene expression on or off. if a repressor protein binds to a dna sequence called a(n) it may block gene expression.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

hope it mark me as brainlieast.
