FTCE Science 4 — Questions and Answers
Question 1: Which best explains why a metal spoon feels colder than a wooden spoon at the same room temperature?
- Metal has a lower temperature than wood at room temperature
- Metal conducts heat away from your hand faster than wood (Correct answer)
- Wood generates heat through a chemical reaction
- Metal reflects heat energy away from your hand
Correct answer: Metal conducts heat away from your hand faster than wood
Metal is a better thermal conductor, so it transfers heat away from your skin rapidly, creating the sensation of coldness.
Question 2: Which describes the difference between mitosis and meiosis?
- Mitosis produces haploid cells; meiosis produces diploid cells
- Mitosis produces two diploid cells; meiosis produces four haploid cells (Correct answer)
- Mitosis only occurs in reproductive organs; meiosis occurs throughout the body
- Mitosis involves two divisions; meiosis involves one division
Correct answer: Mitosis produces two diploid cells; meiosis produces four haploid cells
Mitosis produces two genetically identical diploid daughter cells for growth and repair, while meiosis produces four genetically varied haploid gametes.
Question 3: A teacher demonstrates placing a sealed balloon in the freezer and observing it shrink. Which gas law explains this observation?
- Boyle's Law
- Charles's Law (Correct answer)
- Avogadro's Law
- Gay-Lussac's Law
Correct answer: Charles's Law
Charles's Law states that at constant pressure, gas volume is directly proportional to temperature; lowering temperature decreases volume.
Question 4: Which type of plate boundary is associated with the formation of the Himalayan Mountains?
- Divergent boundary
- Transform boundary
- Convergent continental-continental boundary (Correct answer)
- Convergent oceanic-continental boundary
Correct answer: Convergent continental-continental boundary
The Himalayas formed when the Indian and Eurasian continental plates collided, with neither plate subducting, causing massive uplift.
Question 5: Which best describes the purpose of using a control group in a scientific experiment?
- To manipulate the independent variable
- To provide a baseline for comparing experimental results (Correct answer)
- To ensure all variables are changed simultaneously
- To repeat measurements and calculate averages
Correct answer: To provide a baseline for comparing experimental results
A control group receives no experimental treatment, providing a baseline that allows researchers to attribute observed differences to the independent variable.
Question 6: Which process releases energy stored in glucose molecules and does NOT require oxygen?
- Aerobic respiration
- Photosynthesis
- Anaerobic fermentation (Correct answer)
- Transpiration
Correct answer: Anaerobic fermentation
Anaerobic fermentation breaks down glucose without oxygen, producing ATP along with byproducts like lactic acid or ethanol.
Question 7: A student observes a rock layer containing fossils of marine organisms at the top of a cliff. What can be concluded using the principle of superposition?
- The marine fossils are older than the rocks below them
- The marine fossils formed before the rock layer
- The rock layers below contain more recent fossils
- The rock layers below are older than the marine fossil layer (Correct answer)
Correct answer: The rock layers below are older than the marine fossil layer
The principle of superposition states that in undisturbed rock layers, lower strata are older, so rock below the marine fossil layer is older.
