Which describes prokaryotic chromosomes?
(select all that apply.)

a)are circular in shape

b)have telomeres

c)are found in the cytoplasm

d)contain histone proteins

the correct answers are A and  C. I am positive.

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.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
