Q: What is the name of the process by which plants reduce water loss through their leaves?

Transpiration. Transpiration is the process where plants lose water vapor through small pores (stomata) in their leaves.

Q: What is the name of the layer of the Earth's structure between the crust and the outer core?

Mantle. The mantle is the layer of Earth between the crust and the outer core. It's composed of hot rock that flows slowly over time.

Q: What percentage of Earth's oxygen is produced by the oceans?

At least 50%. At least 50% of Earth's oxygen is produced by ocean phytoplankton through photosynthesis, making them critical to our atmosphere.

Q: What is the name of the ecosystem with the greatest biodiversity on land?

Tropical rainforest. Tropical rainforests contain more species per unit area than any other terrestrial ecosystem, hosting about 50% of Earth's species.

Q: What is the name of the protein in muscles that contracts to produce movement?

Actin and myosin. Actin and myosin are two proteins that work together in muscle cells. When myosin binds to actin and pulls, it causes muscle contraction.

Q: How many chambers does the human heart have?

4. The human heart has four chambers: two upper chambers called atria and two lower chambers called ventricles. This structure enables efficient blood circulation.

Q: What is the name of the hormone produced by the pancreas that regulates blood sugar?
