Answer:
Water molecules stick together by cohesion
Explanation:
This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

Two main factors that affect enzyme activities are temperature and pH value.
Every type of enzymes has their own optimum temperature and pH, where they work the fastest at.
for temperature, if the temperature is too low for the enzyme, they may become inactive, they work slow. Give them their suitable temperature they'll work fast again.
However, if the temperature is too high, the enzyme would be denatured. You cannot use them again.
Denatured enzymes means the enzymes already changes shape of the active site and can no longer bind into substrates and therefore no longer works, no matter if you provide the suitable environment again.
For pH, the concept is same, unless if the pH value is too extreme than the optimum pH, the enzyme will be denatured instead of being inactive.
mobility because reporduction and homeostastis are caratristics of living things while mobility is not.
1)Without photosynthesis: If we didn't have plants, algae and bacteria to do the photosynthesis, CO2, a air pollutant wouldn't be converted in to glucose for those organisms and there would be no more Oxygen released to the atmosphere. Less photosynthesis means less oxygen production and many organisms, like us, would die.
2)Without cellular respiration: Without this process we couldn't convert our food into the energy, ATP, necessary for the cells to function properly. Plus, this process also forms water, and without it, it would be another reason for the death of the cells.
Ultimately, will cause the death of the aerobic organism.
