Along a mid-ocean ridge, rocks _____ moving away from the ridge.
Marat540 [252]

Answer:

A. become older

Explanation:

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.They technically would be old rocks because once the lava dries out it will spew out new rock, pushing away the older rock.

Explanation:

Probability of Leukemia

A. Among traced group

= 4/1,870 persons.

B. Among self-reported group

= 4/443 person.

We can deduce

A higher rate of occurrence in self-reported group which could be causesd by fear of leukemia occurrence or suspicion of their previous exposure at atomic sites

Explain the role of enzymes as biological catalysts that lower the activation energy of a reaction.
tia_tia [17]

Answer:

Enzymes are one kind of protein which functioning as catalyst  that speed up reactions by lowering activation energy.Enzyme accelerate a reaction without altering its chemical equilibrium.

Explanation:

Energy which is required for  start a biochemical reaction is called activation energy.Activation Energy helps to jump and start a thermodynamically favorable reactions.

Enzymes can  many  way to its activation energy.

1. The enzyme may hold the substrates in such a way as to distort the substrate bonds closer to their form in the transition state. This reduces the amount of energy needed to complete the transition.

2.Enzyme create a charge distributor which opposite of transition state his lowers the energy of the transition state and decreases the activation energy.

3.The enzyme may reduce the reaction entropy   by bringing substrates together in the correct orientation to react.

4. The enzyme may provide a completely different chemical pathway for the reaction. It may form new bonds in the ES complex that would be difficult to form without the enzyme.
