Answer:
Option b. Lowering the pH to kill pathogenic bacteria is correct answer.
Explanation:
bacterial motors are sensitive to pH. By decreasing the pH bacterial motors stops working. This was identified in a new research. But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).
Reference: Powell, K. Acid stops bacteria swimming. Nature (2003).
Answer:
reactions
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
I am pretty much sure that C. Lyases is the answer.
Let me give some information about this.
Lyases are the main groups which show peculiarity in having more than several categorised groups having more enzymes than the other four.
Hydrolase does not fit this bill instead they contain less categorised groups.
Other two groups are not even having that much groups.
Hope helps ...
Eukaryotes are larger cells with membrane-bounded organelles.
Prokarotes are not that large and do not have a nucleus or any memberane-bound organelles.
