To answer the questions based on the image:

1. The chemical symbol for Sodium is Na.
2. The ratio of hydrogen and oxygen in water is 2:1.
3. A negative charge can be an electron.
4. Connective tissue options include tendons and adipose.
5. Cartilage is not found in blood.
6. Fats are stored in the human body as adipose tissue.
7. Each neuron has a long tail called an axon.
8. The SI unit of pressure is Pascal.
9. The unit of energy is Joule.
10. Water stored in a dam possesses potential energy.
11. If the speed of a car becomes 2 times, its kinetic energy becomes 4 times.
12. Energy can neither be created nor destroyed.
13. Expression for potential energy is mgh (mass × gravity × height).
14. The commercial unit of energy is kilowatt-hour (kWh).

16a. The slow blood clotting could be due to low platelet count or clotting factors. 16b. Large blood loss is fatal because it reduces oxygen and nutrient delivery to tissues. 16c. The doctor showed concern and provided medical advice.

17a. According to Science, the coolie applies force and work is done. 17b. The values are kindness and helpfulness by both Ravi and the coolie.

18a. Satvik's problem was due to the thin strap causing discomfort. 18b. Pressure is defined as force per unit area, with the SI unit being Pascal. 18c. Adi showed thoughtfulness and generosity.
