1. What is the difference between a prokaryotic cell and a eukaryotic cell?

Correct answer: B

Rationale: - Prokaryotic cells are simpler and do not have a true nucleus. Their genetic material is located in the nucleoid region, which is not enclosed by a membrane. - Eukaryotic cells are more complex and have a true nucleus that houses the genetic material, enclosed within a nuclear membrane. - Both prokaryotic and eukaryotic cells have organelles, but eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while prokaryotic cells lack these membrane-bound organelles.

2. Which of the following is true regarding adipocytes?

Correct answer: B

Rationale: The correct answer is B. Adipocytes are responsible for storing the fat found in adipose tissue. These specialized cells store energy in the form of fat and play a key role in energy balance and metabolism. Adipocytes do not secrete glucose; that function is typically attributed to other cells like pancreatic beta cells. Adipocytes are not involved in the digestive breakdown of fat, as this process primarily occurs in the gastrointestinal system with the help of enzymes. Adipocytes are distinct from the foundational elements of muscles, which are primarily made up of muscle fibers and associated connective tissues.

3. At which of the following ages would ossification most likely take place to replace cartilage at the growth plate?

Correct answer: B

Rationale: Ossification, the process where cartilage is replaced by bone, typically occurs during adolescence, around the age of 18. This is when the growth plates in the bones close, and the bones stop growing in length, leading to the replacement of cartilage with bone tissue. Choice A (5) is incorrect because ossification primarily occurs during adolescence, not early childhood. Choice C (42) is incorrect as ossification is completed well before this age, usually during the late teens or early twenties. Choice D (91) is incorrect as ossification is a process that occurs earlier in life, typically during adolescence, and is not a process that occurs in advanced age.

4. What is the term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure?

Correct answer: B

Rationale: Solubility is the correct term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure. Molarity is a measure of concentration, not the maximum amount that can dissolve. Concentration is a general term for the amount of solute present in a given amount of solvent. Saturation is related to solubility but specifically refers to a state where no more solute can be dissolved in the solvent.

5. Which type of waves exhibit both longitudinal and transverse motion?

Correct answer: B

Rationale: Surface waves exhibit both longitudinal and transverse motion. These waves travel along the boundary between two different mediums, such as water and air, causing particles to move both parallel (longitudinal) and perpendicular (transverse) to the wave's direction of travel. This unique characteristic distinguishes surface waves from other types of waves, making them the correct answer in this context. Electromagnetic waves, like light and radio waves, are purely transverse in nature, propagating through vacuum or different media through oscillating electric and magnetic fields perpendicular to the direction of wave travel. Mechanical waves, including both transverse (e.g., water waves) and longitudinal (e.g., sound waves in air) waves, do not typically exhibit both types of motion simultaneously, unlike surface waves.
