What do most enzymes that utilize atp also require as a cofactor?
a. mg2+
b. nad+
c. thiazolium pyrophosphate
d. coenzyme a

Mg2+

Explanation: ATP(Adenosine triphosphate) is unstable in nature and also shows the property of being electronegative. It is seen that is the electronegative element and it is bonded with the Mg2+ being a positive divalent and thus achieve the stability and reducing the electrostatic repulsion.So, there is the combination between the negatively charged phosphate groups with the Mg2+. Therefore option (a) is the correct answer.

just here for the other one bc they put up with u

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
