If this is true or false than it is FALSE
Answer:
Chritsy must remove option A i.e "Is a transition metal"
Explanation:
Sodium is not a transition metal. It is a group element. Transition metal have very high density and boiling temperature like chromium which is a transition metal. Sodium do not have high density and boiling temperature.
Hence the correct option to be removed is option A i.e "Is a transition metal"
Answer;
-The secondary and tertiary structure of the enzyme.
Explanation;
-Lactase is an enzyme that is found in the small intestine, liver, and kidney of mammals. In the presence of lactase, lactose is cleaved and reduced to its subunits D-galactose and D-glucose, monosaccharides that can eventually be utilized as a source of energy in cells.
-At extremely low pH, molecules move so slowly that reaction rates can be hampered even though the enzyme is still properly folded and active. At extremely high pH, bonds and interactions that exist between the amino acid side chains (R groups) in an enzyme become disrupted. The result is that the enzyme is incapable of maintaining its shape, and therefore unfolds, becoming inactive.
Examples:
The flowers color is compared.
Radish seedlings are measured in height
