Answer #1

27) Lipids are used to form the cell membrane of the cell. Phospholipids form a double layer known as lipid bilayer acts as a permeable membrane of the cell. Option a is the correct answer.

28) Fatty acid heads are negatively charged and are hydrophilic whereas, the fatty acid tails avoid the water interaction and are hydrophobic. Option b is the correct answer.

29) Pentose sugars are present in RNA and DNA. They consist of five carbons. Sugar in RNA is called as ribose. Option c is the correct answer.

30) Pentose sugars are found in DNA. Deoxyribose consists of 5 carbons. Option d is the correct answer.
