Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
<span>Evaporation and transpiration.
</span>
The evaporation process uses the sun radiation or sun’s
thermal energy for vaporization of a water from the land or soil to be water
vapor then in the air. Transpiration on the other hand is the same with evaporation
that involves water molecules to be vaporized into the air but it is located in
the stoma of the plants. It is like evaporation within plants. This is actually
to have homeostasis in plants and still part of the water cycle.
Answer:
Umm...I'm not sure if this is a question where there is MC but if not, the the answer would most likely be, "By actually doing then saying"
Explanation:
The structure that serves as the cell's boundaries from its environment is known as the CELL MEMBRANE. It keeps the bad things from coming in, and releases waste out into the environment.

Answer:
Diffusion
Explanation:
Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.
