Biology

1. What are the building blocks of proteins?

Correct answer: C

Rationale: Rationale: Proteins are macromolecules made up of long chains of amino acids. Amino acids are the building blocks of proteins and are linked together through peptide bonds to form polypeptide chains, which then fold into specific three-dimensional structures to carry out various functions in the body. Sugars (A) are the building blocks of carbohydrates, fatty acids (B) are the building blocks of lipids, and nucleotides (D) are the building blocks of nucleic acids like DNA and RNA.

2. Which group of elements are known for their vibrant colors and use in fireworks?

Correct answer: D

Rationale: Transition metals exhibit diverse electronic configurations, leading to their ability to emit specific colors of light, making them ideal for fireworks.

3. What is the main component of sweat?

Correct answer: C

Rationale: Rationale: - Sweat is primarily composed of water, making up the majority of its content. Water helps regulate body temperature by evaporating from the skin's surface, which cools the body down. - While sweat does contain small amounts of other substances like urea, glucose, and electrolytes, water is the main component that is secreted by sweat glands to help regulate body temperature during physical activity or in response to heat.

4. Energy for most cellular processes is produced in the:

Correct answer: C

Rationale: The correct answer is C: 'Mitochondria.' The mitochondria are known as the powerhouse of the cell, where the process of cellular respiration takes place to produce energy in the form of ATP. The nucleus (option A) houses the cell's genetic material but is not directly involved in energy production. The cytoplasm (option B) is a jelly-like substance that surrounds organelles but is not the primary site of energy production. Ribosomes (option D) are involved in protein synthesis, not energy production. Therefore, the mitochondria play a crucial role in generating energy for most cellular processes.

5. What type of particle carries no charge and mediates the strong nuclear force between protons and neutrons?

Correct answer: C

Rationale: Gluons are the force carriers of the strong nuclear force, holding protons and neutrons together within the nucleus.

6. What property of a substance measures the amount of matter per unit volume?

Correct answer: c

Rationale: Density measures the amount of matter (mass) per unit volume of a substance.
