Enzymes.
Enzymes are responsible to make reactions hard to take place, or even very unlikely to happen, to actually happen. They are proteins that have normally an active binding site where molecules may connect to and preform the reaction. The necessary energy to make a reaction occur is less when aided by enzymes and that's what makes of them catalysts so that reactions may occur even when in lower temperatures.
Cohesion, adhesion and surface tension are different from each other. Adhesion is used in xylem. Surface tension enables an insect to sit on water.
<u>Explanation:</u>
The force of attraction between the molecules of the same type is called cohesion. The force of attraction between the molecules of different type is called adhesion. Tendency of fluid surfaces to shrink to minimum possible area due to the attraction between the liquid molecules is called surface tension.
Adhesion is used in xylem. In xylem water molecules move from the roots to different parts of the plant through the xylem tubes. The adhesive force between the water molecules and xylem walls make the movement of water possible.
Surface tension enables an insect to sit on the surface of a liquid. Due to surface tension the water surface stretches like a membrane due to the higher attractive force between the water molecules.

Answer:
field studies
Explanation:
The documentation and collection of descriptive details of events in nature such as amounts, sizes, colors, smell , behavior, texture e.t.c are all categorized as field studies.
It involves the gathering of raw data outside a laboratory.
- Often times, based on the needs of an experiment, it is desirable to corroborate laboratory studies with field evidences.
- The approach in gathering such data varies from discipline to discipline.
- Most field sampling are usually done in an uncontrolled environment.
