Answere :
Question 21 : The correct option is (a) i.e. atrial natriuretic hormone which reduces blood volume and blood pressure and increase utine volume.
Question 22 : The correct option is (d) i.e. neurotransmitter is a chemical signal that diffuses across the gap between the adjacent neuron to convey a message to next cell.
Question 23 : The statement is true.
Question 24 : The option (b) is correct i.e. E. coli is a pathogen which most likely be responsible for a urinary tract infection caused by improper wiping after defecation.
Question 25 : The option (c) is correct i.e. plasma proteins does not move to any great extent from the blood into the filterate of renal corpuscles.
Question 26 : The option (a) is correct i.e. lung is the respiratory organ of respiratory system that contain alveoli.
Question 27 : The statement is true.
Question 28 : The option (b) is correct i.e. multiple sclerosis is the disease involved in the the destruction of myelin sheath or certain neuron within brain and spinal cord.
Question 29 : The statement is false i.e. The food in pharynx moves to oesophagus not to stomach.
Question 30 : The option (c) is correct i.e.norepinephrine is a neurotransmitter appear to be associated with an energizing "good" feeling and essential in hunger, thrust and sex drive.
Question 31 : The option (d) is correct i.e. Sodium-potassium pump is a specialised membrane proteins that actively transport sodium and potassium ions across the plasma membrane.
