What is basic concept of evolution? […]

What can you taste in a storm? —Oh, ozone Before the rain begins, one of the first odors you may notice as winds pick up and clouds roll in is a sweet, pungent zing in your nostrils. That’s the sharp, fresh aroma of ozone—a form of oxygen whose name comes from the Greek word ozein […]

Can there be fog when it rains? Precipitation Fog: This is fog that forms when rain is falling through cold air. This is common with a warm fronts but it can occur with cold fronts as well only if it’s not moving too fast. Cold air, dry at the surface while rain is falling through […]

Is magnitude and distance the same? Distance is defined to be the magnitude or size of displacement between two positions. How do you find the magnitude and distance? The magnitude of a vector →PQ is the distance between the initial point P and the end point Q . In symbols the magnitude of →PQ is […]

What is the atomic number of 8 protons and 10 neutrons? Fluorine Who uses oxygen? Oxygen therapy is prescribed for people who can’t get enough oxygen on their own. This is often because of lung conditions that prevents the lungs from absorbing oxygen, including: chronic obstructive pulmonary disease (COPD) pneumonia. Can too much supplemental oxygen […]

Why do chips gain mass in salt solution? When the chips were put in distilled water they gain mass because the chips gain water from the surrounding solution due to osmosis. The process of osmosis causes a net flow of water across the semi permeable membrane, from a solution with a high water concentration to […]

What size is a photon? In this way you could say the “size” of photon is basically the width of its wavelength. The wavelength of green light is about 500 nanometers, or two thousandths of a millimeter. The typical wavelength of a microwave oven is about 12 centimeters, which is larger than a baseball. How […]

What are the organelles of cell? An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins. […]
