1. She is hopeful that her unit will make a big turnaround in the succeeding months. Which of

• A. Wonders why things are not what it used to be
• B. Finds solutions to the problems
• C. Integrate the solutions to his day-to-day activities
• D. Selects the best change strategy

Correct answer: C

Rationale: The correct answer is C: 'Integrate the solutions to his day-to-day activities.' In the given scenario, the individual is hopeful about a turnaround in their unit, indicating a desire for positive change. Option C aligns with this by suggesting that the individual is not only finding solutions to the problems (as in option B) but also integrating these solutions into their daily routines. This integration is crucial for sustained improvement and long-term success, making it the most appropriate choice among the options provided.

2. The science of classifying organisms into different groups based on their evolutionary relationships is called:

• A. Taxonomy
• B. Microbiology
• C. Genetics
• D. Epidemiology

Correct answer: A

Rationale: Rationale: Taxonomy is the science of classifying organisms into different groups based on their evolutionary relationships. It involves identifying, naming, and categorizing living organisms according to their similarities and differences. Microbiology (option B) is the study of microorganisms, Genetics (option C) is the study of genes and heredity, and Epidemiology (option D) is the study of the distribution and determinants of health-related states or events in populations.

3. What is the name of the growth plates in children's bones where new bone tissue is formed?

• A. Epiphyses
• B. Diaphysis
• C. Periosteum
• D. Medullary cavity

Correct answer: A

Rationale: The correct answer is A: Epiphyses. Epiphyses are the growth plates located at the ends of children's long bones where new bone tissue is formed. These plates are responsible for longitudinal bone growth until they close during adolescence. The diaphysis (B) is the shaft or main portion of a long bone, while the periosteum (C) is the outer membrane covering the bone. The medullary cavity (D) is the central cavity of bone shafts where bone marrow is stored. Understanding the terminology for different parts of bones is essential for comprehending bone growth and development in children.

4. Which element is found in water and is crucial for biological functions like nerve impulses and muscle contraction?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Sodium plays a key role in maintaining electrolyte balance and transmitting nerve impulses, affecting both muscles and nerves

5. Which technology allows scientists to directly edit the human genome?

• A. Polymerase Chain Reaction (PCR)
• B. Gel electrophoresis
• C. DNA sequencing
• D. CRISPR-Cas9

Correct answer: D

Rationale: Rationale: A) Polymerase Chain Reaction (PCR) is a technique used to amplify a specific segment of DNA through repeated cycles of heating and cooling. PCR is not used for directly editing the human genome. B) Gel electrophoresis is a technique used to separate DNA fragments based on size. It is not used for directly editing the human genome. C) DNA sequencing is a method used to determine the precise order of nucleotides in a DNA molecule. While DNA sequencing is important for understanding genetic information, it is not used for directly editing the human genome. D) CRISPR-Cas9 is a technology that allows scientists to make precise changes to the DNA of living organisms, including the human genome. CRISPR-Cas9 works by guiding the Cas9 enzyme to a specific location in the genome where it can make targeted cuts or edits. This technology has revolutionized genetic research and has the potential for applications

6. What is the process of breaking down fatty acids into acetyl-CoA, a key molecule in cellular respiration, called?

• A. Beta-oxidation
• B. Lipolysis
• C. Carbohydrate catabolism
• D. Nucleic acid catabolism

Correct answer: A

Rationale: Rationale: A) Beta-oxidation is the process of breaking down fatty acids into acetyl-CoA molecules. This process occurs in the mitochondria and is a crucial step in fatty acid metabolism for energy production. B) Lipolysis is the breakdown of fats into fatty acids and glycerol, but it does not specifically refer to the conversion of fatty acids into acetyl-CoA. C) Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production and is not directly related to the conversion of fatty acids into acetyl-CoA. D) Nucleic acid catabolism refers to the breakdown of nucleic acids into nucleotides and does not involve the conversion of fatty acids into acetyl-CoA.
