1. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?

• A. Human papillomavirus (HPV)
• B. Chlamydia
• C. Gonorrhea
• D. Syphilis

Correct answer: B

Rationale: Chlamydia is the correct answer because if left untreated, it can lead to serious complications such as pelvic inflammatory disease (PID) in women and epididymitis in men, both of which can cause infertility. Chlamydia is a common sexually transmitted infection that often presents with no symptoms, making it important for individuals to get tested regularly, especially if they are sexually active. It is crucial to detect and treat Chlamydia early to prevent long-term consequences such as infertility. Human papillomavirus (HPV) can lead to genital warts and certain types of cancer but is not typically associated with infertility. Gonorrhea and syphilis can cause serious health problems if untreated, but infertility is more commonly associated with Chlamydia.

2. An uncharged atom has an electron configuration of 1s² 2s² 2p⁶ 3s² and a mass number of 14. How many protons does it have?

• A. 14
• B. 6
• C. 8
• D. 12

Correct answer: B

Rationale: The number of protons in an atom is determined by the atomic number, which is equal to the number of protons in the nucleus. The electron configuration given corresponds to carbon (C) with 6 protons. The atomic number of an element is the same as the number of protons in its nucleus, so in this case, the atom has 6 protons. Choices A, C, and D are incorrect because they do not correspond to the correct number of protons for an atom with the given electron configuration and mass number. Therefore, option B, 6 protons, is the correct answer.

3. Which term refers to a position toward the head? Example: The hand is part of the superior extremity.

• A. Superior
• B. Inferior
• C. Medial
• D. Lateral

Correct answer: A

Rationale: The correct answer is 'Superior.' 'Superior' refers to a position toward the head, while 'inferior' is the term for a position toward the feet. In the given example, the hand belongs to the superior extremity, which includes structures closer to the head. 'Inferior' is incorrect as it refers to a position away from the head or toward the feet. 'Medial' describes a position closer to the midline of the body, while 'lateral' refers to a position farther away from the midline.

4. What are chromosomes made of?

• A. DNA and RNA
• B. DNA and protein
• C. Protein and RNA
• D. DNA and lipids

Correct answer: B

Rationale: Chromosomes are made up of DNA and associated proteins. These proteins help package and organize the DNA within the cell, playing a crucial role in gene regulation and cell division. While RNA is involved in various cellular processes, it is not a primary component of chromosomes. Lipids are not a fundamental component of chromosomes, which primarily consist of DNA and proteins.

5. What is a submicroscopic entity that is considered nonliving because it lacks cellular structure and consists of nucleic acids encapsulated in a protein coat called a capsid?

• A. Bacteria
• B. Fungus
• C. Virus
• D. Protozoa

Correct answer: C

Rationale: The correct answer is C: Virus. Viruses are not considered living organisms because they lack cellular structure. Instead, they are composed of nucleic acids (either DNA or RNA) enclosed in a protein coat called a capsid. Bacteria (choice A), fungus (choice B), and protozoa (choice D) are all living organisms with cellular structures, unlike viruses. Therefore, they are incorrect choices for this question.
