Solution:From Platelets blood clotting factor released. When there is an injury, platelets release molecules into the blood that help activate clotting factors. One important clotting factor is fibrin, a long, thin and sticky protein, When fibrin is turned on, it forms a mesh to hold the platelet plug in place. This mesh also traps red blood cells, forming a blood clot.

Correct Answer: (a) chambers of heart
Solution:Pulse is felt due to the rhymic contraction and relaxation of the chamber of the heart. The primary source of the pulse is the heart itself.

65. When eggs are heated, the transparent liquid portion around yolk turns solid and turbid white. This happens due to the thermal denaturation of

Correct Answer: (b) proteins
Solution:When eggs are heated, the transparent liquid portion around yolk turns solid and turbid white.

This happen due to the thermal denaturation of protein. As we heat egg white, the delicate protein molecules within it begin to unfold. The exquisite folding of amino acid chains in albumin gets disrupted. This loss of structure causes albumin to change from a translucent, soluble form to a solid white mass. The once-clear egg white becomes opaque and coagulated due to the denaturation process.

1. A price index captures the change in the average price of a constant basket of commodities. the case of an activity that produces a positive externality is the difference between the social benefit and the private benefit at the optimum.
2. If the price index takes values 100, 110 and 121 in three consecutive years respectively, then the inflation rates in the 2nd and 3rd years are 10% and 21% respectively.

Select the correct answer using the codes given below.

Correct Answer: (a) Only 1
Solution:Only statement 1 is correct. Statement 2 is incorrect. To calculate the inflation rate between two years, we use the following formula:
Inflation Rate = ((Price Index in Year 2 Price Index in Year 1) / Price Index in Year 1) x 100
Inflation Rate in the 2nd Year
((110-100)/100) × 100 = 10%
Inflation Rate in the 3rd Year
((121-110)/110) × 100 ? 10%

Therefore, the inflation rate in the 3rd year is approximately 10%, not 21%.

68. Which of the following statements is/are correct?

These reserves are typically held in short-term instruments (like government bonds).

69. Which one of the following statements is not correct?

Correct Answer: (a) The market mechanism over-produces a good that generates positive externality.
Solution:The market mechanism doesn't over produce a good that generates positive externality rather than the market underproduces it. This is because the market only considers the private benefits and costs associated with the good, not the social benefits.

To correct this market failure, governments often intervene with policies like subsidies or regulations to encourage the production and consumption of goods with positive externalities.
