Answer:
Temperature
PH
Explanation:
Enzymes are organic catalysts that speeds up the rate of a chemical reaction. Their activities are affected by temperature and pH of the environment among other factors.
- At extreme temperatures, enzymes can easily be denatured and they will cease to act.
- At extremes of pH, they can also be adversely affect.
Enzymes generally have temperature and pH window for their activity.
The number of waves passing in a certain amount of time
The answer is d I think. Don’t quote me if I’m wrong
Hello!
This is a difficultly easy question, mostly because it seems like all of the answers would be right, but if I had to choose one, I would say (D) because this option gives the most detail.
Option A only tells us how fast a car was moving
Option B only tells us the rate the water falls and how fast it is going
Option C only tells how far and not the speed or destination
Option D is correct, it tells us the speed/rate, the destination, and what is moving
Therefore, Option (D) is correct
If this helps, please mark brainliest, have a great day!!
Answer:
Lower
Explanation:
Surface tension occurs because molecules at the surface do not have molecules above them, so they cohere more strongly to their neighbours.
The stronger cohesive forces make it more difficult to move an object through the surface than when it is beneath the surface.
The attractive forces in water are strong because of hydrogen bonding.
A hexane molecule is nonpolar, so the only attractions are the weak London dispersion forces.
The cohesive forces at the surface are much lower than those in water, so the surface tension of hexane is lower than that of water at the sane temperature.
