1. In the female reproductive system, what structure produces eggs (ova)?

• A. Fallopian tubes
• B. Ovaries
• C. Uterus
• D. Vagina

Correct answer: A

Rationale: The correct answer is B: Ovaries. The ovaries are the primary reproductive organs in the female body responsible for producing eggs (ova) through a process called ovulation. The fallopian tubes serve as the passageway for the egg to travel from the ovary to the uterus for potential fertilization. The uterus is where a fertilized egg implants and develops into a fetus during pregnancy. The vagina is the muscular canal that connects the uterus to the outside of the body and serves as the birth canal during childbirth. Therefore, the ovaries are specifically responsible for the production of eggs in the female reproductive system.

2. What is the product of the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH)?

• A. NaCl + H2O
• B. NaOH + HCl
• C. Na2Cl + H2O
• D. NaClO3 + H2

Correct answer: a

Rationale: The reaction between HCl and NaOH results in the formation of sodium chloride (NaCl) and water (H2O).

3. Which term describes a substance's ability to undergo a change that transforms it into a different substance?

• A. Density
• B. Mass
• C. Reactivity
• D. Volume

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, transforming it into one or more different substances with new properties.

4. Which element shares the same group (family) on the periodic table with helium (He)?

• A. Neon (Ne)
• B. Boron (B)
• C. Carbon (C)
• D. Oxygen (O)

Correct answer: A

Rationale: Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.

5. The kidneys are bean-shaped organs responsible for filtering waste products from the blood. What is the main nitrogenous waste product the kidneys eliminate?

• A. Carbon dioxide
• B. Ammonia
• C. Urea
• D. Glucose

Correct answer: C

Rationale: The correct answer is C: Urea. The kidneys filter waste products from the blood to maintain a proper balance of electrolytes and remove toxins. Urea is the main nitrogenous waste product formed from the breakdown of proteins in the liver. It is then excreted by the kidneys through urine. Carbon dioxide is a waste product of cellular respiration and is eliminated primarily through the lungs. Ammonia is a toxic compound that is converted to urea in the liver before being excreted by the kidneys. Glucose is a sugar that is normally reabsorbed by the kidneys and not excreted as waste.

6. What is the functional group present in ethers?

• A. Hydroxyl
• B. Carbonyl
• C. Ether
• D. Amine

Correct answer: C

Rationale: Ethers have the functional group -O-, representing an oxygen atom bonded to two alkyl or aryl groups. The other choices are associated with different functional groups.
