Which of the following explains how enzymes affect chemical reactions? Enzymes increase the energy necessary for a reaction to occur.

Enzymes donate energy to the reactions, allowing nonspontaneous reaction to proceed forward

Enzymes allow the reactions to occur at higher temperatures with greater kinetic energy.

Enzymes lower activation energy which speeds up the conversion of reactants to products

Which of the following is caused by reproductive isolation within a species? a. a decrease in gene flow b. an increase in genetic flow c. a decrease in genetic drift d. an increase in gene flow

What are levels of ecology and how can we remember them

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
