Answer:
A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.
Explanation:
Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude.
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.
Answer:
All of the above individuals demonstrate these errors
Explanation:
A whole skeletal muscle is considered an organ of the muscular system. From a sample response:)
Genotype frequency: RR is dominant, Rr is heterozygous and rr is recessive.
R^2+2Rr+r^2 = 1
R = 0.85
R^2= 0.85*0.85 = 0.7225
