Answer:
False

Negatively charged particles repel other negatively charged particles. Typically a negatively charged particle is electropositive and wants a positive molecule and/or cation (positive ion) to form a bond with. Negative molecules want positive molecules and vise versa.
Answer:
The urease will not catalyze any reaction.
Explanation:
The hydrolysis reaction of urea is:
(NH₂)₂CO + 2 H₂O + H⁺ ⇒ 2 NH₄⁺ + HCO₃⁻
Urease is an enzyme that catalyzes the urea hydrolysis reaction. Enzymes are very specific referring to the substrates they catalyze. If the solution does not contain urea, the urease will not bind to any of the substances in the solution, so it will not catalyze any reaction in the solution.
