Answer : 1. "Hydrophobic"
Explanation :
Answer: A) Hydrophobic Explanation: Lipids are soluble in solvents of low polarity, which simply means that lipids are soluble in nonpolar solvents. This solubility property is a result of the large nonpolar regions that are indicative of the lipid molecule.

Answer : 1. "Y"
Explanation :
Answer: A) Y Explanation: If you add all the terms of the LHS of equality, then the last letter of the sum written in words would give you the RHS. 1 + 1 + 1 + 1 = 4 = FOUR 2 + 2 + 2 + 2 = 8 = EIGHT 3 + 3 + 3 + 3 = 12 = TWELVE 4 + 4 + 4 + 4 = 16 = SIXTEEN So, following the same pattern. 5 + 5 + 5 + 5 = 20 = TWENTY That gives us our answer to 5 5 5 5 = "Y".

Answer : 4. "All the above"
Explanation :
Answer: D) All the above Explanation: Intermolecular forces : The forces of attraction present in between the molecules or atoms or compounds is termed as intermolecular forces. The molecule HCl is composed of hydrogen and chlorine atom. There is high difference in electronegativities therefore, it is polar in nature. The H end of HCl is permanently slightly positive charge. The Cl end of HCl has a permanent slight negative charge. the "H" in one molecule is attracted to the "Cl" in a neighbor. The intermolecular force is weak compared to a covalent bond. But this dipole-dipole interaction is one of the stronger intermolecular attractions. It also has hydrogen bonding and dispersion forces. Dispersion forces are the weakest forces which are present in between all molecules or atoms.Hydrogen bonds are present in molecules having at least one H-A bond where A is the strong electronegative atom (mainly F, Cl and N).
