1. What is the formula for calculating molarity?

• A. M = n/V
• B. M = n/L
• C. M = mol/L
• D. M = mol/dm³

Correct answer: a

Rationale: All of these choices are equivalent to the original formula. The symbol "n" represents the number of moles of solute, and the symbol "V" represents the volume of the solution in liters. The symbol "L" is an abbreviation for "liters," and "dm³" is an alternative way to represent liters.

2. Where does cellular respiration, the process of converting chemical energy into ATP, take place in eukaryotic cells?

• A. Nucleus
• B. Ribosomes
• C. Mitochondria
• D. Golgi apparatus

Correct answer: C

Rationale: Rationale: Cellular respiration, the process of converting chemical energy into ATP, takes place in the mitochondria of eukaryotic cells. The mitochondria are known as the powerhouse of the cell because they are responsible for generating most of the cell's ATP through the process of cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the primary energy currency of the cell. The other organelles listed in the options (nucleus, ribosomes, and Golgi apparatus) do not play a direct role in cellular respiration.

3. A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

• A. 300mg
• B. 600mg
• C. 750mg
• D. 900mg

Correct answer: D

Rationale: Rationale: - The patient receives 150mg of medication every 4 hours. - To calculate how many milligrams the patient will receive in 24 hours, we need to determine how many times the medication is administered in 24 hours. - Since the medication is administered every 4 hours, there are 24 hours in a day, so the medication will be administered 24 / 4 = 6 times in 24 hours. - Therefore, the total amount of medication the patient will receive in 24 hours is 150mg x 6 = 900mg.

4. What is the relationship between mass and inertia?

• A. Mass is a measure of inertia
• B. Mass has no relation to inertia
• C. Inertia is a measure of weight
• D. Inertia increases with decreasing mass

Correct answer: a

Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.

5. 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

6. What is the formula to calculate acceleration?

• A. Acceleration= Mass Force ​
• B. Acceleration= Force Mass ​
• C. Acceleration= Time Distance ​
• D. Acceleration= Time Change in Velocity ​

Correct answer: A

Rationale: Acceleration is calculated as the change in velocity divided by the time taken.
