1. 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.

2. What is the Aufbau principle?

• A. The principle that electrons fill orbitals in order of increasing energy.
• B. The principle that electrons cannot be in the same orbital with the same spin.
• C. The principle that the maximum number of electrons in an orbital is 2n^2, where n is the energy level of the orbital.
• D. The principle that the attractive force between an electron and the nucleus is inversely proportional to the distance between them.

Correct answer: A

Rationale: The Aufbau principle is a fundamental concept in atomic structure that determines the order in which electrons fill the available orbitals in an atom. It states that electrons occupy orbitals in order of increasing energy levels, starting with the lowest energy level and progressing to higher energy levels. This principle is based on the fact that electrons in lower energy levels are more stable and have a lower energy state than electrons in higher energy levels.

3. The word "obscurity" can be replaced with which of the following without changing the meaning?

• A. Prominence
• B. Seclusion
• C. Destruction
• D. Transformation

Correct answer: B

Rationale: Both "obscurity" and "seclusion" imply being hidden or unknown. Prominence, destruction, and transformation do not convey the same meaning.

4. What is the largest muscle in the human body?

• A. Gluteus maximus (buttocks)
• B. Quadriceps femoris (thighs)
• C. Erector spinae (back)
• D. Pectoralis major (chest)

Correct answer: A

Rationale: The gluteus maximus is the largest muscle in the human body, located at the back of the hip and extending from the sacrum to the femur. It is a powerful muscle that plays a crucial role in extending the hip joint, enabling walking, running, and climbing stairs.

5. What is the scientific name for the building blocks of proteins?

• A. Residues
• B. Monomers
• C. Macromolecules
• D. Peptides

Correct answer: B

Rationale: Rationale: - Proteins are made up of long chains of amino acids. - Amino acids are the building blocks of proteins and are considered monomers. - Monomers are the individual units that can be linked together to form larger molecules called polymers. - In the context of proteins, amino acids are the monomers that are linked together through peptide bonds to form polypeptide chains, which then fold into functional proteins. - Residues refer to the specific amino acids within a protein after certain modifications or cleavages have occurred, so it is not the correct term for the building blocks of proteins. - Macromolecules are large molecules made up of smaller subunits, such as proteins, nucleic acids, and carbohydrates, but they are not the specific building blocks of proteins. - Peptides are short chains of amino acids linked by peptide bonds, but they are not the fundamental building blocks of proteins.

6. What is a contraceptive method that uses hormones to prevent ovulation?

• A. Spermicide
• B. Barrier method (condom, diaphragm)
• C. Combined oral contraceptive pill
• D. Intrauterine device (IUD)

Correct answer: C

Rationale: The correct answer is C: Combined oral contraceptive pill. This method uses hormones, such as estrogen and progestin, to prevent ovulation, thicken cervical mucus to block sperm, and thin the uterine lining to prevent implantation of a fertilized egg. Spermicide (A) is a chemical that kills sperm but does not prevent ovulation. Barrier methods (B) like condoms and diaphragms physically block sperm from reaching the egg. Intrauterine devices (IUDs) (D) are inserted into the uterus and work by either releasing hormones or creating a barrier to prevent fertilization, but they do not specifically target ovulation.
