Answer-30 (C) 3,1,2,5,4 i.e.Chemical, cell,tissue,organ,organ system.
Explanation-
The structural organization of the human body is categorised as chemical, cell, tissue, organ and organ system.
Chemical level is the simplest level in the structural hierarchy and comprises of atoms, molecules and organelles within the cell.
Cell is the basic structural and functional unit of life.
Tissue is the group of similar cells that unite to perform similar functions.

Answer 31- (D) Synovial
Explanation-
Diarthrosis or the synovial joint is the most common and movable joint due to the presence of synovial fluid and articular capsule.
Answer 32- (C) Activation energy.
Explanation-
Activation energy is defined as the minimum amount of energy that must be available for the processing of a chemical reaction. It is denoted as Ea. The lower be the activation energy, higher is the rate of the reaction.
Answer-33 (D) prevent sensitization of the mother.
Explanation-
RhoGam is the medication to prevent the Rh immunization and is administered by the Intramuscular injection. This helps to prevent Rh-sensitization in pregnant mother.
Answer 34- (B) Superior to the mouth
