The answers to the given questions are as follows:

12. The cup-like hollow proximal part of each nephron is known as: (B) Bowman's capsule

Bowman's capsule is a cup-like structure present at the proximal part of the nephron. It is also known as the renal corpuscle capsule.

13. Autotrophic organisms convert carbon dioxide and water into carbohydrates in the presence of: (A) carbon dioxide and sunlight

Sunlight is necessary for autotrophs to excite the chlorophyll and carbon dioxide is required during the formation of carbohydrates.

14. There is an equation 'X', which contain equal number of atoms of each element on both sides. What is 'X'? (A) balanced equation

Equal number of atoms of each element on both sides indicates that the equation is balanced. If the number is not equal, then it is called an unbalanced equation.

15. Which of the following are present in a dilute aqueous solution of hydrochloric acid? (B) H30+, CI

Hydrochloric acid dissociated to form hydrogen ions and chloride ions. Hydrogen ion combines with water molecule forming hydronium ion. Thus, hydronium ions and chloride ions will be present.

16. The role of nasal cavity in Human Respiratory system is: (1) Filtration of inhaled air (ii) Removal of germs and dust (iii) Moistening of inhaled air (C) (i), (ii) and (iii)

The nasal cavity has hairs present which helps in the filtration of inhaled air. The mucous secreted in the nasal cavity captures the germs and dust and also moistens the inhaled air.

17. Carefully study the diagram of the human Circulatory system with labels 1, 3, 2 and 6. Select the option which gives correct identification and main function and/or characteristic. (A) (1) Pulmonary Artery: The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. - Pulmonary artery is the only artery that carries blood away from the heart.
