1. What is the term for the number of moles of solute per liter of solution?
- A. Molarity
- B. Molality
- C. Normality
- D. Concentration
Correct answer: A
Rationale: Molarity is defined as the number of moles of solute per liter of solution. The other choices are different concentration units.
2. Identify the antonym of the word "pensive":
- A. joyous
- B. thoughtful
- C. curious
- D. introspective
Correct answer: A
Rationale: "Joyous" is the opposite of "pensive," which means thoughtful and slightly melancholy.
3. Which statement accurately describes the Linnaean system of classification?
- A. It focuses on evolutionary relationships between organisms
- B. It uses dichotomous keys for identification
- C. It groups organisms based on shared functions
- D. It emphasizes a hierarchical ranking system
Correct answer: D
Rationale: Rationale: The Linnaean system of classification, developed by Carl Linnaeus, is based on a hierarchical ranking system where organisms are grouped into categories based on shared characteristics. This system organizes organisms into a hierarchy of increasingly specific categories, from broad to narrow, such as kingdom, phylum, class, order, family, genus, and species. This hierarchical approach allows for the systematic organization and classification of a wide variety of organisms based on their similarities and differences.
4. A syringe holds 3ml of liquid. How many syringes are needed to measure 15ml of liquid?
- A. 3
- B. 5
- C. 7
- D. 9
Correct answer: B
Rationale: Divide the total liquid volume (15ml) by the syringe capacity (3ml/syringe) to get 5 syringes.
5. What is the name of the tough, fibrous connective tissue that attaches muscle to bone?
- A. Fascia
- B. Perimysium
- C. Tendon
- D. Ligament
Correct answer: C
Rationale: The correct answer is C: Tendon. A tendon is the tough, fibrous connective tissue that attaches muscle to bone. Fascia (A) is a connective tissue that surrounds muscles, while perimysium (B) is the connective tissue surrounding bundles of muscle fibers. Ligaments (D) are tough bands of tissue that connect bones to other bones. Understanding the function and structure of tendons is crucial for biomechanics and movement as they play a vital role in transmitting forces from muscles to bones, allowing for movement and stability in the body.
6. What is the process of converting lactic acid back into pyruvate called?
- A. Glycolysis
- B. Gluconeogenesis
- C. Cori cycle
- D. Oxidative phosphorylation
Correct answer: C
Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.
