physics

1. Which energy conversion occurs in a solar cell?

Correct answer: d

Rationale: Solar cells convert solar energy (sunlight) directly into electrical energy.

2. Which of the following is the main organ responsible for producing antibodies?

Correct answer: C

Rationale: Rationale: Antibodies are proteins produced by specialized white blood cells called B lymphocytes (B cells). These B cells mature in the bone marrow, where they undergo a process of differentiation and maturation to become plasma cells that secrete antibodies. The bone marrow is the primary site for the production of B cells and antibodies in the immune system. The thymus gland is responsible for the maturation of T lymphocytes (T cells), not antibody production. The spleen and lymph nodes play roles in filtering and trapping pathogens but are not the main organs responsible for producing antibodies.

3. What property of a wave is measured in Hertz (Hz)?

Correct answer: d

Rationale: Frequency, the number of oscillations per second, is measured in Hertz (Hz).

4. Lysosomes are known as "suicide bags" of the cell. What enzymes do they contain?

Correct answer: A

Rationale: Lysosomes are membrane-bound organelles containing hydrolytic enzymes responsible for breaking down various macromolecules, cellular waste, and foreign substances. These enzymes perform hydrolysis, a process where water molecules are used to break down larger molecules into smaller components. This function earned lysosomes the nickname 'suicide bags' as they can initiate cell death (apoptosis) by releasing their enzymes when needed. Ligases, transferases, and oxidoreductases are enzymes with different functions such as forming bonds, transferring molecules, and catalyzing redox reactions, respectively, which are not typically found in lysosomes. Therefore, the correct answer is A: 'Hydrolytic enzymes.'

5. What is the formula for calculating density?

Correct answer: c

Rationale: Density is defined as the mass of a substance divided by its volume. The formula for density is Density = Mass / Volume.

6. Which state of matter has both definite volume and definite shape?

Correct answer: a

Rationale: Solids have both definite volume and definite shape. The particles in solids are closely packed, maintaining their positions, resulting in a fixed shape and volume.
