In the given graph, it can be seen that the energy consumed by Reaction B is much lower compared to Reaction A during which both of the reaction reached the peak. This now suggest that because the reaction energy required for B is lowered, then the answer to this item is the second option.

Answer: Reaction A is not enzyme-catalyzed, while reaction B is enzyme-catalyzed

Explanation:

The minimum energy required by the reactants to cross the energy barrier is called as activation energy. The use of enzyme lowers the activation energy as it takes the reaction through a different pathway which is lower in energy. Thus a enzyme catalyzed reaction has low activation energy as compared to a non catalyzed reaction.

Describe the difference between gravitational force and strong nuclear force

arsen [322]

Gravitational force is much weaker, because it is the force of gravity, or the force that makes smaller objects be pulled towards a much bigger one with a certain amount of force.

Now strong nuclear force, which is very strong, keeps the atomic particles in an atom from separating, and the reason it is so powerful is because the particles in an atom repel each other and this force keeps them from doing .that

What effect does light have on plant growth?

Varvara68 [4.7K]

Explanation:

Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

When you need to produce a variety of diluted solutions of a solute, you can dilute a series of stock solutions. A stock solutio

8090 [49]

Answer:

Volume of stock solution needed = 6.0299 mL

Explanation:

<u> </u>Dilution consists of lowering the amount of solute per unit volume of solution. It is achieved by adding more diluent to the same amount of solute.

This is deduced when thinking that both the dissolution at the beginning and at the end will have the same amount of moles.

M1 = 6.01 M stock solution concentration

M2 = 0.3624 M diluted solution concentration

V2 =100 mL diluted solution volume

V1 = ? stock solution volume

M1 * V1 = M2 * V2

$V1=\frac{M2*V2}{M1} =\frac{0.3624M*100mL}{6.01M} =6.0299 mL$
