1. What is the process of cells restoring damaged or lost tissues called?

• A. Cell division
• B. Cell differentiation
• C. Cell growth
• D. Cell regeneration

Correct answer: D

Rationale: Rationale: A) Cell division refers to the process by which a cell divides into two daughter cells. B) Cell differentiation is the process by which cells become specialized for specific functions. C) Cell growth is the increase in cell size or number. D) Cell regeneration is the process of cells restoring damaged or lost tissues by replacing or repairing the damaged cells. This process is essential for healing wounds and maintaining tissue integrity.

2. What is 0.5 liters in ml?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.

3. What term refers to the mechanical act of breathing?

• A. Diffusion
• B. Perfusion
• C. Respiration
• D. Ventilation

Correct answer: D

Rationale: Ventilation is the correct answer as it specifically refers to the mechanical process of breathing air in and out of the lungs. Diffusion (choice A) is the movement of molecules from an area of high concentration to low concentration, not related to the mechanical act of breathing. Perfusion (choice B) is the process of blood flow through the tissues and organs, not directly related to breathing mechanically. Respiration (choice C) involves the exchange of oxygen and carbon dioxide at the cellular level, different from the mechanical act of breathing.

4. What is the anatomical term for the back of the body? Example: Shoulder blade.

• A. Anterior
• B. Superior
• C. Posterior
• D. Inferior

Correct answer: C

Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

5. What is the smallest unit that can encode for a trait?

• A. A codon
• B. A gene
• C. A nucleotide
• D. A chromosome

Correct answer: B

Rationale: The correct answer is B - a gene. Genes are the smallest units that can encode for a trait as they contain the specific instructions for producing a particular characteristic or protein. While codons are sequences of nucleotides that code for specific amino acids in a protein, they are not the smallest unit that encodes for a trait. Nucleotides are the building blocks of DNA and RNA, and chromosomes are made up of DNA and proteins, containing many genes.
