1. What is the term used to describe the inability of the kidneys to effectively filter waste products from the blood?

• A. Dehydration
• B. Kidney failure
• C. Incontinence
• D. Nephritis

Correct answer: B

Rationale: Kidney failure is the term used to describe the inability of the kidneys to effectively filter waste products from the blood. Dehydration refers to insufficient fluid intake and not the kidney's filtering function. Incontinence is the loss of bladder control, not related to kidney filtration. Nephritis is the inflammation of the kidneys, not specifically related to the kidneys' inability to filter waste products.

2. What is the process by which a fertilized egg implants itself in the lining of the uterus?

• A. Fertilization
• B. Implantation
• C. Gestation
• D. Parturition

Correct answer: B

Rationale: Implantation is the correct answer. It is the process where a fertilized egg attaches itself to the lining of the uterus to establish a pregnancy. Fertilization is the initial step where the sperm and egg fuse to form a zygote. Gestation refers to the period of fetal development within the uterus. Parturition is the process of giving birth and is not related to the implantation of the fertilized egg, which occurs earlier in the reproductive process.

3. What is the major difference between somatic and germline mutations?

• A. Somatic mutations usually benefit the individual while germline mutations usually harm them.
• B. Since germline mutations only affect one cell, they are less noticeable than the rapidly dividing somatic cells.
• C. Somatic mutations are not expressed for several generations, but germline mutations are expressed immediately.
• D. Germline mutations are usually inherited while somatic mutations will affect only the individual.

Correct answer: D

Rationale: The major difference between somatic and germline mutations is that germline mutations are usually inherited and can be passed on to offspring, while somatic mutations occur in non-reproductive cells and only affect the individual in which they occur. This means that germline mutations have the potential to be present in future generations, while somatic mutations do not.

4. Which of the following is an example of a zoonotic disease?

• A. The common cold
• B. Influenza (the flu)
• C. Malaria
• D. HIV/AIDS

Correct answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

5. Which represents the correct order of airflow in the lungs?

• A. Bronchi, trachea, alveoli, bronchioles
• B. Alveoli, bronchioles, bronchi, trachea
• C. Trachea, bronchi, bronchioles, alveoli
• D. Bronchioles, alveoli, trachea, bronchi

Correct answer: C

Rationale: The correct order of airflow in the lungs starts with air entering through the trachea, moving into the bronchi, then proceeding to the bronchioles, and finally reaching the alveoli where gas exchange occurs. Therefore, the correct sequence is Trachea, Bronchi, Bronchioles, Alveoli, making choice C the accurate representation of the airflow in the lungs. Choices A, B, and D are incorrect because they do not follow the anatomical path of airflow in the lungs as air moves from the trachea to the bronchi, then bronchioles, and finally the alveoli for gas exchange.
