1. In a parallel circuit, the ___________ through each component is the same.

• A. current
• B. voltage
• C. resistance
• D. wattage

Correct answer: A

Rationale: In a parallel circuit, the current through each component is the same. This is because the components in a parallel circuit are connected across the same voltage source, so they all experience the same voltage across their terminals. The total current entering the parallel circuit is then split up among the various components, but the current through each component remains the same as the total current. Choices B, C, and D are incorrect. In a parallel circuit, voltage across each component may vary, resistance may differ, and wattage is related to power, not the equality of current through each component.

2. What are muscle contractions that normally move food along the human digestive system known as?

• A. defecation
• B. osmosis
• C. peristalsis
• D. circulation

Correct answer: C

Rationale: Muscle contractions that move food along the human digestive system are known as peristalsis. Peristalsis consists of a series of coordinated muscular contractions and relaxations that help propel food through the esophagus, stomach, and intestines, facilitating efficient digestion and nutrient absorption. Defecation refers to expelling waste from the body, osmosis is the movement of water across a membrane, and circulation relates to the movement of blood in the body's circulatory system, not directly involved in food transportation along the digestive tract.

3. Why are bacteria and blue-green algae often classified together?

• A. Both are gymnosperms.
• B. Both are prokaryotes.
• C. Both are autotrophs.
• D. Both are pathogens.

Correct answer: B

Rationale: Bacteria and blue-green algae (cyanobacteria) are often classified together because they are both prokaryotes. Prokaryotes are unicellular organisms that lack a membrane-bound nucleus and other membrane-bound organelles. This characteristic distinguishes them from eukaryotic organisms, which have these membrane-bound structures. Choice A is incorrect because gymnosperms are seed-producing plants with naked seeds, not bacteria or blue-green algae. Choice C is incorrect because being an autotroph (able to produce its own food) is not a reason for classifying them together. Choice D is incorrect because not all bacteria and blue-green algae are pathogens; many of them are beneficial or neutral to other organisms.

4. In the world of pharmaceuticals, a recall policy is a policy involving the ___________.

• A. ability to remember
• B. the withdrawal of products
• C. manufacture of cosmetics
• D. effectiveness of customers

Correct answer: B

Rationale: In the world of pharmaceuticals, a recall policy is a policy involving the withdrawal of products from the market, typically due to safety concerns, defects, contamination, or other issues that could potentially harm consumers. This process is essential to protect public health and ensure the safety and quality of pharmaceutical products. Choice A, 'ability to remember,' is incorrect as it does not relate to the concept of recalling products in the pharmaceutical industry. Choice C, 'manufacture of cosmetics,' is incorrect as it is unrelated to pharmaceutical recalls. Choice D, 'effectiveness of customers,' is also incorrect as it does not pertain to the purpose of a recall policy in the pharmaceutical field.

5. Before his death at age 82, comedian Rodney Dangerfield's motto was, 'I don't get _____.'

• A. respect
• B. sympathy
• C. attention
• D. care

Correct answer: A

Rationale: The correct answer is 'A: respect.' Rodney Dangerfield was famously known for his catchphrase 'I don't get no respect,' which perfectly aligns with the concept of respect being his motto. The other choices, 'B: sympathy,' 'C: attention,' and 'D: care,' do not accurately capture Dangerfield's well-known persona and catchphrase. Therefore, 'A: respect' is the most suitable answer.
