Which of the following statements is correct with regard to the types of chemical bonds common in biological molecules? Weak bonds include covalent, hydrogen, and ionic bonds. The strongest bond is one that involves sharing of electrons between atoms. Hydrogen bonds and hydrophobic interactions are too weak to have any important function in biological molecules. Non-polar molecules are made of atoms that share electrons equally.  Question 2    1 / 1 point In biochemistry, some molecules are considered hydrophobic and some are considered hydrophilic. Which of the following  statements about this topic is/are correct? Hydrophilic molecules are soluble (i.e., can move freely) in water. Hydrophobic molecules are soluble (i.e., can move freely) in water. Opposites attract: hydrophilic molecules are attracted to hydrophobic molecules.
