1. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. Define work in physics.

• A. Force applied to an object at rest
• B. Force exerted by an object in motion
• C. Transfer of energy through motion along a direction
• D. Measure of an object's potential energy

Correct answer: c

Rationale: Work in physics is the transfer of energy when a force is applied and the object moves in the direction of the force.

3. Deficiency in which vitamin can lead to a condition called pernicious anemia, affecting vitamin B12 absorption in the digestive system?

• A. Vitamin A
• B. Vitamin B12 (cobalamin)
• C. Vitamin D
• D. Vitamin E

Correct answer: B

Rationale: The correct answer is B: Vitamin B12 (cobalamin). Pernicious anemia is a condition caused by a deficiency in vitamin B12, which is essential for the production of red blood cells and for the proper functioning of the nervous system. This vitamin is primarily absorbed in the digestive system, particularly in the ileum of the small intestine. In pernicious anemia, there is a lack of intrinsic factor, a protein produced by the stomach, which is necessary for the absorption of vitamin B12. Deficiencies in other vitamins like Vitamin A, Vitamin D, or Vitamin E do not directly lead to pernicious anemia. Therefore, the correct answer is Vitamin B12.

4. Which word has the same root as "unscathed"?

• A. category
• B. scar
• C. scratch
• D. category

Correct answer: C

Rationale: Both "unscathed" and "scratch" relate to damage or physical marks.

5. What is the term for a solution that has exactly the same concentration of solute as another solution?

• A. Saturated solution
• B. Unsaturated solution
• C. Isotonic solution
• D. Concentrated solution

Correct answer: c

Rationale: An isotonic solution has the same concentration of solute as another solution. The other choices do not accurately describe an isotonic solution.

6. Describe the mechanism by which genes are transmitted from parents to offspring.

• A. Blending of parental genes, resulting in an average of their traits.
• B. Random assortment of alleles during meiosis, leading to unique combinations in each offspring.
• C. Inheritance of solely dominant alleles, masking the influence of recessive ones.
• D. Direct transfer of both parental genomes, creating identical copies of the parents.

Correct answer: B

Rationale: Rationale: A) Blending of parental genes, resulting in an average of their traits, is not an accurate description of how genes are transmitted. In reality, genes are not blended but rather passed down in discrete units. B) Random assortment of alleles during meiosis is the correct mechanism by which genes are transmitted from parents to offspring. During meiosis, homologous chromosomes separate, and alleles are randomly distributed to the gametes, leading to unique combinations of genes in each offspring. C) Inheritance of solely dominant alleles, masking the influence of recessive ones, is not an accurate representation of gene transmission. Offspring inherit alleles from both parents, and the expression of dominant or recessive traits depends on the specific combination of alleles. D) Direct transfer of both parental genomes, creating identical copies of the parents, is not how genes are transmitted. Offspring inherit a unique combination
