Which of the following statements is correct with regard to the types of chemical bonds common in biological molecules? Hydrogen bonds and hydrophobic interactions are too weak to have any important function in biological molecules. Weak bonds include covalent, hydrogen, and ionic bonds. The strongest bond is one that involves sharing of electrons between atoms. 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. Hydrophilic molecules contain some atoms that are electronegative--i.e., they do not share electrons equally with their  covalent bond partners. Hydrophobic molecules are soluble (i.e., can move freely) in water. Opposites attract: hydrophilic molecules are attracted to hydrophobic molecules. Question 3    1 / 1 point Water, the basis of life on Earth, has some particular properties, including which of the following? In a liquid state, its molecules tend to stick together with great adhesion.
