An atom that has 7 protons, 5 neutrons, and 8 electrons has an atomic number of 7. Atomic number is equal to the amount of protons in an atom.
The water vapor in the relatively warmer, and more moist air condensed, hence fogging your glasses. Warm moist air comes in contact with a colder surface, you get condensation.
Hope this helps!
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.
