Answer:
D. There will always be waste produced that can be used for energy.
Explanation:
Biomass energy is a renewable energy source because its does not have limited supply. We can always grow trees and crops, and waste will always exist.
The statements of the old cell theory are:
1. All organisms are composed of cells
2. The cell is the basic unit of life
3. Cells are produced from existing cells
The modern cell theory's statements are:
1. The cell contains hereditary information which is passed to daughter cells
2. All cells are basically the same in composition and activity
3. All basic functions occur in cells
4. Cell activities depend on intracellular structures
As is visible from the statements, the old cell theory was not as detailed and lacked the understanding of the function, structure and behavior of cells that the current theory possesses. This difference has come about after years of research, through which scientists understood the functions of cells and elaborated on the theory's statements.
Answer:
Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels overtime by not allowing water to INFILTRATE.
Greenhouse gases trap the sun's heat and this is how we can feel it. Without greenhouse gases the earth's average temperature would be 30 degrees less. Other greenhouse gases include water vapor and methane. Increases in the levels of Greenhouse gasses are responsible for present day global warming.
Infiltration is the process by which water enters the soil and eventually becomes part of the groundwater.
Answer:
Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
Explanation:
Photosynthesis makes the glucose that is broken down by cellular respiration. Cellular respiration converts the glucose that is made by photosynthesis to oxygen. Photosynthesis converts the glucose that is made by cellular respiration to carbon dioxide
