1. Which of the following is a MAJOR consequence of a stroke?

Correct answer: C

Rationale: A major consequence of a stroke is brain damage due to interrupted blood flow. Strokes occur when blood flow to the brain is blocked or reduced, leading to the death of brain cells. This interruption in blood flow results in brain damage, which can cause physical and cognitive impairments such as paralysis, speech difficulties, memory problems, and sensory disturbances. The severity and location of the stroke determine the extent of the consequences experienced by the individual. Choices A, B, and D are incorrect. Irregular heart rhythm is not a direct consequence of a stroke but may occur as a complication. Rapid weight gain or loss and chronic fatigue with muscle weakness are not typically considered major consequences of a stroke, which primarily affects the brain due to interrupted blood flow.

2. What is the difference between a prokaryotic cell and a eukaryotic cell?

Correct answer: B

Rationale: - Prokaryotic cells are simpler and do not have a true nucleus. Their genetic material is located in the nucleoid region, which is not enclosed by a membrane. - Eukaryotic cells are more complex and have a true nucleus that houses the genetic material, enclosed within a nuclear membrane. - Both prokaryotic and eukaryotic cells have organelles, but eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while prokaryotic cells lack these membrane-bound organelles.

3. Which of the following is the main organ responsible for regulating sleep?

Correct answer: B

Rationale: The main organ responsible for regulating sleep is the hypothalamus. The hypothalamus plays a crucial role in controlling the body's circadian rhythm, which is the internal clock that regulates the sleep-wake cycle. It receives input from the eyes about light and darkness, aiding in determining when it's time to sleep or wake up. Additionally, the hypothalamus regulates the production of melatonin by the pineal gland, a hormone that helps control sleep patterns. While the thalamus relays sensory information to the brain, the pituitary gland is primarily responsible for hormone production and release, and the pineal gland produces melatonin under the control of the hypothalamus. Therefore, the hypothalamus is the correct choice as the main organ involved in sleep regulation.

4. What type of cells compose the epidermis?

Correct answer: D

Rationale: The correct answer is D: Epithelial. The epidermis is composed of epithelial cells, specifically called keratinocytes, which are responsible for producing keratin, a protein that provides the skin with strength and flexibility. Epithelial cells form the protective outer layer of the skin and play a crucial role in skin repair and regeneration. Choice A - Osteoclasts are cells involved in bone remodeling, not found in the epidermis. Choice B - Connective tissue cells are not the primary cells found in the epidermis. They are more commonly found in the dermis, providing structural support and elasticity to the skin. Choice C - Dendritic cells are part of the immune system and are present in the skin to help recognize pathogens and activate the immune response. However, they are not the main cell type that composes the epidermis.

5. Which of the following functions is NOT performed by the integumentary system, the skin?

Correct answer: D

Rationale: The integumentary system, which includes the skin, performs various functions like protecting internal tissues from injury, waterproofing the body, and helping regulate body temperature. The function of returning fluid to the blood vessels is primarily associated with the lymphatic system, not the integumentary system. The skin contributes to fluid balance by regulating sweating and preventing excessive water loss, but it does not directly return fluid to the blood vessels, making this the correct answer. Choices A, B, and C are functions directly related to the integumentary system and are essential for maintaining the body's overall health and well-being.
