1. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: b

Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.

2. Which condition is characterized by inflammation of the inner lining of the stomach?

• A. Gastroesophageal reflux disease (GERD)
• B. Diverticulitis
• C. Ulcerative colitis
• D. Gastritis

Correct answer: D

Rationale: The correct answer is D, gastritis. Gastritis refers to the inflammation of the inner lining of the stomach, which can be caused by various factors such as excessive alcohol consumption, prolonged use of NSAIDs, or bacterial infections like H. pylori. Gastroesophageal reflux disease (GERD) is characterized by the backflow of stomach acid into the esophagus, not inflammation of the stomach lining. Diverticulitis is inflammation of small pouches that can develop in the colon, while ulcerative colitis is inflammation in the large intestine. Therefore, gastritis best fits the description of inflammation in the inner lining of the stomach.

3. Chyle, a milky white fluid, is transported by lymphatic vessels from the:

• A. Lungs
• B. Intestines
• C. Kidneys
• D. Skin

Correct answer: B

Rationale: The correct answer is B: Intestines. Chyle is a milky white fluid that is formed in the small intestine during digestion, mainly from the absorption of dietary fats. It is rich in fats and lymphocytes. Lymphatic vessels in the intestines, called lacteals, absorb the chyle and transport it through the lymphatic system. Chyle eventually enters the bloodstream via the thoracic duct. The lungs are responsible for gas exchange, not the transport of chyle. The kidneys are involved in filtering blood and producing urine. The skin is the body's largest organ responsible for protection, temperature regulation, and sensation, but it is not involved in transporting chyle.

4. What is the name for the process where a solid changes directly into a gas?

• A. Evaporation
• B. Sublimation
• C. Condensation
• D. Melting

Correct answer: B

Rationale: Sublimation occurs when a solid directly transforms into a gas without passing through a liquid phase.

5. What happens to the acceleration of an object when the force acting on it is increased, assuming the mass remains constant?

• A. Acceleration increases
• B. Acceleration decreases
• C. Acceleration remains constant
• D. Acceleration becomes zero

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass is constant and force increases, acceleration also increases.

6. Which sentence uses the correlative conjunction "either/or" correctly?

• A. You can either come to the party or stay home.
• B. Either she will go to the concert, or he will.
• C. I'm not sure whether I should go swimming or running.
• D. He likes both pizza and pasta, so he can have either.

Correct answer: A

Rationale: Option Aa uses "either/or" to present two exclusive options.
