Electronegativity can be used to predict the character of a bond between two elements. If the difference between the electronegativity of two atoms is greater than 2.0, which type of bond will be formed? An isotopic bond
A polar covalent bond
A nonpolar covalent bond
An ionic bond

What are some things that limit population growth?

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
