                  How beneficial or harmful mutations are depends on the environment.              

Are mutations usually beneficial or usually harmful?

many complex chemical interactions. Everything that happens at the level of the cell is based on how molecules interact!

They are molecules that have the same molecular formula (chemical symbols and subscripts indicating the numbers of atoms in a molecule or compound), but different structures.

what are Structural Isomers?

Denaturation is the process where proteins or nucleic acids lose their characteristic folded structure due to some external stress or compound

what is denaturation?

It must be testable

They become resistant to antibiotics by mutations. They can also pass genes horizontal evolution by a couple ways such as conjugation, transformation, and transduction.

No, Only the rate. Which is the speed of the reaction because enzymes work by reducing the activation energy which is only the start of the reaction.

Do enzymes change the amount of energy added or released by bonds being formed or broken?n.

are electrons in the outermost electron shell surrounding an atom that can participate in bonds. Bonds between atoms help each atom complete its octet by donating, accepting, or sharing valence electrons.

What are Valence electrons?
