Cholesteatomas are typically caused by repeated ear infections or a tear in the eardrum, which allows skin cells to accumulate and form a cyst-like growth. Treatment usually involves surgical removal of the cholesteatoma to prevent complications such as hearing loss, infection, or damage to the facial nerve.Rate this question:

Which of the following best describes the chewing of food?
- A.
Emulsification
- B.
Mechanical digestion
- C.
Peristalsis
- D.

B. Mechanical digestionExplanation
Mechanical digestion is the process of physically breaking down food into smaller pieces through actions like chewing, grinding, and churning. This process increases the surface area of the food, making it easier for enzymes to further break it down and facilitate digestion. Therefore, mechanical digestion best describes the chewing of food. Emulsification is the process of breaking down fat globules into smaller droplets, peristalsis is the wave-like muscle contractions that propel food through the digestive tract, and absorption is the process of nutrients being taken up by the body.Rate this question:

Someone who has high cholesterol and doesn't exercise very often will probably have:
- A.
Hypertension
- B.
A normal blood pressure
- C.
Hypotension
Correct Answer
A. HypertensionExplanation
Someone who has high cholesterol and doesn't exercise very often is likely to have hypertension. High cholesterol can lead to the buildup of plaque in the arteries, causing them to narrow and become less flexible. This can increase blood pressure as the heart has to work harder to pump blood through the narrowed arteries. Additionally, lack of exercise can contribute to weight gain and poor cardiovascular health, further increasing the risk of hypertension. Therefore, the combination of high cholesterol and lack of exercise is likely to result in hypertension.Rate this question:

A heart attack
- B.
A stroke
- C.
Burst blood vessels

Dizziness
Correct Answer
D. DizzinessExplanation
A patient who has hypotension, which is low blood pressure, is likely to experience dizziness. Hypotension can cause inadequate blood flow to the brain, leading to symptoms such as lightheadedness, fainting, and dizziness. This is because the brain does not receive enough oxygen and nutrients when blood pressure is low. While a heart attack, stroke, or burst blood vessels can also have various symptoms, dizziness is more directly associated with hypotension.Rate this question:
