One half of a duplicated chromosome is called a sister chromatid
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.
The slopes show that sucrose gradient affects change in weight.
The slopes will be different because higher gradient concentration of sucrose will result in the higher amount of water moved. This means the higher sucrose gradient concentration, the more change in weight of the water.
I would think most likely red and white
The answer to this is the nucleus
