Explain the concept of reaction equilibrium and how the activities of enzymes depend on the temperature, ionic conditions, and p

H of the surroundings.

Julli [10]3 years ago

Enzymes are special proteins that help all of the chemical reactions in our bodies occur more easily (faster --- ergo why they call enzymes 'catalysts').

Each enzyme has a preferred or optimal pH and temperature that it 'likes' to function at. If that particular pH or temperature is altered, the ability of that enzyme to do its job is altered (for the worse) as well.

Alex_Xolod [135]

Answer: Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).

Process where air in the lower atmosphere flows together resulting in mid-afternoon thunderstorms.
emmainna [20.7K]

Answer:

Small scale convergence

Explanation:

This term in meteorology occurs in a convergence zone; a region in the atmosphere where two air flows meet and interact, usually resulting in major weather conditions. A Small-scale convergence will produce situations ranging from isolated cumulus clouds to large areas of thunderstorms.

5. A dedicated earth science student using
const2013 [10]

Answer:

(2) 988.5 mb.

Explanation:

The air pressure descends as we ascend. In other words, they are inversely proportional.

The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.

Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
