Explanation:
Cellular Metabolism
The living cells of every organism constantly use energy to survive and grow. Cells break down complex carbohydrates into simple sugars that the cell can use for energy. Muscle cells may consumer energy to build long muscle proteins from small amino acid molecules.
Answer:
Most sedimentary rocks are formed in level layers. Therefore, the occurrence of tilted rock layers is evidence of mountain building. ... Tilting can also result when rocks are pushed upward, or uplifted. In some areas of the world, rock layers are so severely tilted that they may be bottom side up. Layered rocks form when particles settle from water or air. Steno's Law of Original Horizontality states that most sediments, when originally formed, were laid down horizontally. ... Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata.

Whereas an onion epidermal cell has a cell wall, a human cheek cell does not. Instead, a semi-permeable membrane surrounds the cytoplasm of the cheek cell. While there are chloroplasts present in onion cells, they are absent in cheek cells. </span>
Mitosis results in two cells that are duplicates of the original cell. This kind of cell division occurs throughout the body, except in the reproductive organs. This is how most of the cells that make up the body are made and replaced.<span>Meiosis results in cells with half the number of chromosomes, 23 instead of the normal 46. These are the eggs and sperm. </span>
Answer: See below
Explanation:
Solar energy: Advantages: Solar energy is pollution free and causes no greenhouse gases to be emitted after installation. Disadvantages: Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
Wind energy: Advantages: It doesn't pollute air like power plant relying on combustion of fossil fuel. Disadvantages: Wind turbines can be a threat to wildlife (e.g. birds, bats).
Hydroelectric energy: Advantages: Hydroelectric energy is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Disadvantages: Electricity generation and energy prices are directly related to how much water is available. A drought could potentially affect this.
