Answer: Reducing the activation energy can increase the rate of a reaction.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products leading to increased rate of reaction.
Thus a catalyst speeds up the reaction by decreasing the activation energy.

Explanation:
I know what these are because I have the vocabulary
D. it produces male and female sex cells
In meiosis, a cell
splits into four cells, also splitting the chromosome count in half from
the original cell. This is a critical stage for sexual reproduction in
that the cells then match up with other haploid cells produced by
meiosis from another parent to create a new organism. These sex cells
have both male and female chromosomes and the resulting sex depends on
how the cells match up with those of the other parent.
