20. What is a renewable source of energy?
Answers:
1. The SI unit for temperature is Kelvin (K).
2. The mitochondria function as the powerhouses of the cell, producing energy in the form of ATP.
3. Fossil fuels primarily store chemical energy.
4. Boyle's law states that the volume of a given amount of gas is inversely proportional to its pressure at a constant temperature.
5. The lens in the human eye helps to focus incoming light onto the retina, allowing for clear vision.
6. Chlorofluorocarbons (CFCs) are responsible for the depletion of the ozone layer.
7. A lever works by leveraging a fulcrum point to amplify or redirect the force applied to it.
8. Tides on Earth are primarily caused by the gravitational pull of the Moon and the Sun.
9. A catalyst speeds up a chemical reaction without being consumed itself.
10. Photosynthesis is the process by which green plants convert sunlight, carbon dioxide, and water into glucose and oxygen.
11. Red blood cells transport oxygen from the lungs to the body's tissues.
12. An atom is a neutral particle consisting of protons, neutrons, and electrons, while an ion has a positive or negative charge due to the loss or gain of electrons.
13. The pH scale indicates the acidity or alkali...Read more
