1. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?

Correct answer: C

Rationale: Asthma is a chronic respiratory condition characterized by inflammation of the airways in the lungs, leading to symptoms such as wheezing, shortness of breath, chest tightness, and coughing. Pneumonia is an infection in the lungs caused by bacteria, viruses, or fungi, leading to symptoms like fever, cough, and difficulty breathing. Emphysema is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs, resulting in shortness of breath and a chronic cough. Pleurisy, on the other hand, is inflammation of the lining around the lungs, causing chest pain that worsens with breathing or coughing. Therefore, the correct term for the inflammation of the airways in the lungs with symptoms of wheezing and difficulty breathing is Asthma.

2. What occurs in each of the three phases of the uterine cycle?

Correct answer: D

Rationale: The correct answer is D. In the proliferative phase of the uterine cycle, the uterine lining thickens in preparation for a possible pregnancy. Ovulation occurs around day 14 of the cycle. The menstrual phase is when the uterine lining sheds if pregnancy has not occurred. Choice A is a duplicate of the correct answer. Choice B is incorrect as ovulation occurs during the mid-cycle, which is the ovulatory phase, not the secretory phase. Choice C is incorrect because the uterine lining sheds during the menstrual phase, not the secretory phase.

3. Which organ produces bile to aid in digestion?

Correct answer: B

Rationale: The correct answer is B: Liver. The liver produces bile, which is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The pancreas secretes digestive enzymes, not bile. The gallbladder stores bile but does not produce it. The stomach produces gastric juices, not bile, to aid in digestion.

4. Which term describes the quantity of matter in an object and is measured in kilograms or grams?

Correct answer: B

Rationale: Mass is the quantity of matter in an object and is commonly measured in kilograms or grams. It is a fundamental property of matter and remains constant regardless of the object's location. Weight, in contrast, refers to the force of gravity acting on an object and is measured in newtons. Volume represents the amount of space an object occupies and is typically measured in cubic units like cubic meters or cubic centimeters. Density, on the other hand, is the mass of an object per unit volume, and its unit is, for example, kilograms per cubic meter. Therefore, the correct answer is 'Mass' as it specifically describes the quantity of matter in an object, regardless of the gravitational pull on it. 'Weight,' 'Volume,' and 'Density' do not directly represent the quantity of matter in an object but rather different properties related to it.

5. DNA has both a 'sense' and 'antisense' strand. What is true about the antisense strand?

Correct answer: B

Rationale: The correct answer is B. The antisense strand runs 3' to 5', which is opposite to the direction of the sense strand. It serves as the template strand for transcription, where an RNA molecule is synthesized complementary to the antisense strand. Choice A is incorrect because the antisense strand runs in the opposite direction. Choice C is incorrect as the antisense strand is primarily involved in transcription, not replication. Choice D is incorrect as the direction of DNA storage is not determined by the antisense strand.
