Physics

1. What is the difference between heat and temperature?

Correct answer: B

Rationale: Heat is a form of energy transfer, while temperature reflects the average kinetic energy of particles within a substance.

2. What is the measure of the total amount of space occupied by an object?

Correct answer: d

Rationale: Volume is the measure of the total amount of space occupied by an object and is typically measured in cubic units such as cubic meters or liters.

3. The spleen, an organ associated with the lymphatic system, plays a crucial role in:

Correct answer: B

Rationale: The correct answer is B: 'Filtering blood and destroying old red blood cells.' The spleen is part of the lymphatic system and acts as a blood filter, removing old or damaged red blood cells and helping to fight infections. It does not play a role in regulating blood sugar levels (A), producing digestive enzymes (C), or secreting hormones (D). Understanding the function of the spleen in filtering blood and removing old red blood cells is crucial for grasping its role in maintaining overall health and immunity.

4. Diabetic nephropathy, a complication of diabetes, affects the:

Correct answer: D

Rationale: The correct answer is D: Nephrons. Diabetic nephropathy is a type of kidney disease that occurs as a complication of diabetes. It specifically affects the nephrons, which are the functional units of the kidneys responsible for filtering waste and excess fluids from the blood to produce urine. Damage to the nephrons can lead to kidney failure and other serious complications in individuals with diabetes. Therefore, understanding the impact of diabetes on the nephrons is crucial for managing diabetic nephropathy effectively.

5. Which of the following properties is NOT characteristic of a covalent bond?

Correct answer: B

Rationale: Covalent bonds are formed by the sharing of electrons between atoms. This sharing results in the formation of molecules with directional bonding, where the atoms are held together in a specific orientation. Covalent compounds generally have low melting and boiling points compared to ionic compounds, as the intermolecular forces in covalent compounds are weaker. Additionally, covalent compounds do not conduct electricity in the solid state because the electrons are localized between the atoms and not free to move and carry charge.

6. Which type of cell is responsible for carrying oxygen throughout the body?

Correct answer: D

Rationale: The correct answer is D: Red blood cell. Red blood cells, also known as erythrocytes, are responsible for carrying oxygen throughout the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and transports it to tissues and organs. Nerve cells (option A) transmit electrical signals, muscle cells (option B) are involved in movement, and skin cells (option C) form the outer layer of the skin and provide protection.
