Anatomy

1. Which type of brain wave activity is often seen during REM sleep, associated with dreaming?

Correct answer: D

Rationale: During REM (rapid eye movement) sleep, the brain is highly active, and theta waves are the dominant brain wave pattern. Theta waves are associated with deep relaxation, creativity, and dreaming. Delta waves are typically seen in deep sleep stages, not during REM sleep. Alpha waves are present when we are awake but relaxed, while beta waves are associated with active thinking and concentration. Therefore, theta waves are the correct answer for brain wave activity during REM sleep.

2. When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), the resulting product is:

Correct answer: A

Rationale: This is a classic neutralization reaction, forming water and a salt (sodium chloride).

3. Emerging infectious diseases (EIDs) pose a significant public health threat because they are:

Correct answer: C

Rationale: Rationale: Emerging infectious diseases (EIDs) are a significant public health threat because they are characterized by being new or newly identified diseases that are rapidly evolving. These diseases can spread quickly within populations due to factors such as globalization, travel, urbanization, and changes in climate. EIDs often present challenges to medical professionals as they may not be well-understood initially, making it difficult to develop effective treatments or preventive measures. While some EIDs can be treatable with existing antibiotics, the rapid evolution of these diseases can lead to the development of drug resistance, further complicating treatment efforts. Additionally, EIDs are not limited to affecting animals; they can also have serious implications for human health and well-being.

4. The word "obscurity" can be replaced with which of the following without changing the meaning?

Correct answer: B

Rationale: Both "obscurity" and "seclusion" imply being hidden or unknown. Prominence, destruction, and transformation do not convey the same meaning.

5. Cystitis is an inflammation of the:

Correct answer: B

Rationale: The correct answer is B: Bladder. Cystitis is an inflammation of the bladder, typically caused by a bacterial infection. Symptoms include frequent and urgent urination, along with pain or discomfort in the pelvic area. The kidneys (option A) are responsible for filtering blood and producing urine, but they are not the site of inflammation in cystitis. The ureters (option C) are the tubes that connect the kidneys to the bladder and are not typically affected by cystitis. The urethra (option D) is the tube that carries urine from the bladder out of the body, but it is not where the inflammation occurs in cystitis.

6. What is the process of removing waste products from the cell called?

Correct answer: A

Rationale: Rationale: A) Exocytosis is the process by which cells expel waste products or other substances by fusing a vesicle containing the waste with the cell membrane, releasing its contents outside the cell. This process is essential for maintaining cellular homeostasis by removing waste products from the cell. B) Endocytosis is the process by which cells take in substances by engulfing them in a vesicle formed from the cell membrane. This process is the opposite of exocytosis and is used to bring substances into the cell. C) Phagocytosis is a type of endocytosis where cells engulf solid particles or other cells to form a vesicle called a phagosome. This process is used by immune cells to engulf and destroy pathogens. D) Pinocytosis is a type of endocytosis where cells engulf fluids and dissolved solutes. This process allows cells to take in nutrients and
