Is Sugar an inorganic compound? Explanation: Yes sugars are organic compounds, as organic compounds are defined as Carbon containing compounds with hydrogen attached most of the time. These organic compounds can be synthesized in living beings. they are even used by living being as a source of energy. Is glucose an inorganic compound? Glucose is […]
What protects the cell and is selectively permeable?
What protects the cell and is selectively permeable? A selectively permeable (sometimes called semi-permeable) membrane allows some molecules across but not others. JOB: The cell membrane controls what enters and exits the cell and thus protects the cell. How do organelles help keep the cell alive? Core organelles are found in virtually all eukaryotic cells. […]
What is an example of mutation in evolution?
What is an example of mutation in evolution? Even deleterious mutations can cause evolutionary change, especially in small populations, by removing individuals that might be carrying adaptive alleles at other genes. Figure 2: The history of the gray treefrog, Hyla versicolor, is an example of mutation and its potential effects. What is the most common […]

What causes capacitors to discharge?
What causes capacitors to discharge? If a path in the circuit is created, which allows the charges to find another path to each other, they’ll leave the capacitor, and it will discharge. For example, in the circuit below, a battery can be used to induce an electric potential across the capacitor. How fast do capacitors […]
Do plants take oxygen out of water?
Do plants take oxygen out of water? Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water. At night and on very cloudy days, algae and submerged plants remove oxygen from the […]
How can a sailboat move without electricity?
How can a sailboat move without electricity? Explanation: Wind and water as a source of energy will cause the sailboat to move. As long as the wind is blowing the sailboats will continue to move. The speed the sailboat travels will be determined by the force of the wind. Do sailboats use lift? Sails and […]
