The answer would be D) The growing population is taxing Earth’s resources which could lead to the extinction of many species (I just got this right)
Dmitri Mendeleev is most credited for the table.
<span>I believe the answer is A. hydrophobic. Inside the biological membranes are lipids (hydrophobic) molecules. As you may know the membranes are lipid bilayers. In order to place proteins, which are polymers of amino acids, you would need to create an like-to-like environment. The R groups of amino acids will interact with this hydrophobic lipid bilayer environment and will need to display the same characteristics to keep the plasma membrane intact and not cause unwanted disruption. Therefore, R groups of amino acids in biological membranes should be hydrophobic. </span>
They both are formed through the attraction of atoms possessing opposite polarities. Hydrogen bonds is a relatively weak bond between two oppositely charged sides of two or more molecules and in an ionic bond, an atom gives away one or more electrons to another atom, which means the ionic bond is stronger.
