MAP MAP Science 1 — Questions and Answers
Question 1: What is photosynthesis?
- The process by which plants use sunlight, water, and CO2 to make food (Correct answer)
- The process by which animals digest food
- The process by which cells divide
- The process by which rocks form
Correct answer: The process by which plants use sunlight, water, and CO2 to make food
Photosynthesis is the process plants use to convert sunlight, water, and carbon dioxide into glucose and oxygen.
Question 2: Which cell organelle is known as the powerhouse of the cell?
- Mitochondria (Correct answer)
- Nucleus
- Ribosome
- Vacuole
Correct answer: Mitochondria
The mitochondria produce ATP (energy) through cellular respiration, earning the nickname 'powerhouse of the cell.'
Question 3: Which step of the water cycle involves water vapor cooling and turning into liquid water?
- Condensation (Correct answer)
- Evaporation
- Precipitation
- Transpiration
Correct answer: Condensation
Condensation occurs when water vapor in the atmosphere cools and converts back into liquid water, forming clouds and droplets.
Question 4: Which planet in our solar system is closest to the Sun?
- Mercury (Correct answer)
- Venus
- Earth
- Mars
Correct answer: Mercury
Mercury is the closest planet to the Sun, orbiting at an average distance of about 36 million miles.
Question 5: What does Newton's First Law of Motion state?
- An object at rest stays at rest unless acted upon by an unbalanced force (Correct answer)
- For every action there is an equal and opposite reaction
- Force equals mass times acceleration
- Gravity pulls all objects downward at the same rate
Correct answer: An object at rest stays at rest unless acted upon by an unbalanced force
Newton's First Law states that an object will remain at rest or in uniform motion unless acted upon by an external force.
Question 6: What is an ecosystem?
- A community of living organisms interacting with their physical environment (Correct answer)
- The study of plant life in a region
- A single organism and its habitat
- The total amount of energy in a food chain
Correct answer: A community of living organisms interacting with their physical environment
An ecosystem includes all the living organisms (biotic factors) and nonliving components (abiotic factors) interacting in a specific area.
