Biology

1. 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.

2. What is the product of the complete combustion of propane (C3H8)?

Correct answer: a

Rationale: Complete combustion of hydrocarbons produces carbon dioxide (CO2) and water.

3. What is the term for the number of moles of solute per liter of solution?

Correct answer: A

Rationale: Molarity is defined as the number of moles of solute per liter of solution. The other choices are different concentration units.

4. A garden bed has a side length of 8 meters. What is its perimeter?

Correct answer: C

Rationale: : Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.

5. The element responsible for the green color of leaves is:

Correct answer: A

Rationale: Magnesium is the central element of chlorophyll, the pigment responsible for photosynthesis

6. What is the significance of cell division?

Correct answer: D

Rationale: Cell division is a fundamental process that is essential for the growth, repair, and reproduction of all living organisms. It plays a crucial role in ensuring that organisms maintain their proper size and shape, and it allows for the replacement of damaged or worn-out cells. Cell division is also essential for sexual reproduction, as it is the process by which haploid gametes (sex cells) are produced. These gametes fuse during fertilization to form a diploid zygote, which ultimately gives rise to a new organism.
