Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.

The label on a bag of salt-free pretzels indicates that their chips are "low-fat." this means the pretzels provide 3 gram(s) of fat or less per serving.
Low-fat diets are diets in which the fats are reduced. Low-fat diets are produced in order to prevent diseases such as obesity and heart diseases. Food manufacturers usually use nutrient claims such as '‘low fat’' to indicate the nutritional value of their products. A ‘low fat’ food contains not more than 3g of fat per 100g of food (for solids) and not more than 1.5g fat per 100g (for liquids).

Answer;
petit arm
Explanation;
All human chromosomes have 2 arms, the p (short) arm and the q (long) arm. They are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division.
The symbol "p" stands for "petit", small in French, while "q" was chosen merely because it was the next letter in the alphabet.
Answer:
In this case, the scientist want to test the presence of the limonite in the yellow rocks, So, proposed hypothesis should include the color of rock they want to observe and the posssible outcome, which need to be tested. So, a proposed hypothesis can be: The rocks, which have yellow color are made up of mineral lime.
