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

The difference in the electronegativity of two atoms determines their bond type. If the electronegativity difference is more than 1.7, the bond will have an ionic character. If the electronegativity difference is between 0.4 and 1.7, the bond will have a polar covalent character.

I hope this helps!!!

when it is at an intermediate population density

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
