1. What is the name for the smallest amount of an element that can exist independently and retain its chemical properties?

• A. Molecule
• B. Atom
• C. Compound
• D. Mixture

Correct answer: A

Rationale: An atom is the fundamental building block of an element, consisting of a nucleus and electrons.

2. An element with atomic number 26 and mass number 56 is most likely to be:

• A. Iron (Fe)
• B. Cobalt (Co)
• C. Nickel (Ni)
• D. Manganese (Mn)

Correct answer: A

Rationale: Iron (Fe) - Fe-56 has 26 protons and aligns with the given atomic number and mass number.

3. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.

• A. table
• B. leg
• C. ouch
• D. stubbed

Correct answer: C

Rationale: Interjections express emotions or sudden feelings. "Ouch" conveys a feeling of pain.

4. What is the main component of bile, a substance that aids in fat digestion?

• A. Proteins
• B. Carbohydrates
• C. Bile salts
• D. Vitamins

Correct answer: C

Rationale: Rationale: Bile is a digestive fluid produced by the liver and stored in the gallbladder. Bile salts are the main component of bile that aid in the digestion and absorption of fats in the small intestine. Bile salts help emulsify fats, breaking them down into smaller droplets that can be more easily digested by enzymes. Proteins, carbohydrates, and vitamins are not the main components of bile and do not play a significant role in fat digestion.

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

• A. Nucleus
• B. Cytoplasm
• C. Mitochondria
• D. Ribosomes

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.
