How is energy transferred in a bicycle? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that […]
Why do electrons lose or gain electrons?
Why do electrons lose or gain electrons? Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms). […]
How do RBC survive without nucleus?
How do RBC survive without nucleus? The red blood cells without nuclei, called reticulocytes, subsequently lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum. The spleen acts as a reservoir of red blood cells, but this effect is somewhat limited in humans. Is RBC a living cell? rbcs are living […]
How many electrons can cytochrome c accept?
How many electrons can cytochrome c accept? one electron What happens if cytochrome c is inhibited? Cyanide, azide, and carbon monoxide all bind to cytochrome c oxidase, inhibiting the protein from functioning and leading to the chemical asphyxiation of cells. NO and CN− will compete with oxygen to bind at the site, reducing the rate […]
How did Brahe actually die?
How did Brahe actually die? The famed 16th century Danish astronomer and mathematician Tycho Brahe was long assumed to have died from poisoning. Recently, archaeologists pored over his skeleton to reveal the real cause of his early death: a fatal combination of obesity, diabetes, and alcoholism. Does Tycho Brahe have a wax nose? In the […]
How many types of proteins are there?
How many types of proteins are there? Protein is the basic component of living cells and is made of carbon, hydrogen, oxygen, nitrogen and one or more chains of amino acids. The three types of proteins are fibrous, globular, and membrane. How many proteins are there in humans? 400,000 proteins How many proteins are in […]
What frequency is 75 meters?

All Frequencies in MHz 160 Meters: 1.885, 1.900, 1.945, 1.985 75 Meters: 3.825, 3.870 (West Coast), 3.880, 3.885 40 Meters: 7.290, 7.295 20 Meters: 14.286 Is 80 meters upper or lower sideband? Lower sideband (LSB)–The common single-sideband operating mode on the 40, 80 and 160-meter amateur bands. Upper sideband (USB)–The […]
What frequency means?
What frequency means? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. What happens to pitch when frequency […]
Were there any omnivorous dinosaurs?
Were there any omnivorous dinosaurs? Only a few of the known dinosaurs were omnivores (eating both plants and animals). Some examples of omnivores are Ornithomimus and Oviraptor, which ate plants, eggs, insects, etc. Does not eating meat make your skin better? Beyond just helping with stubborn pimples, going vegan can also improve your complexion, said […]
Is fission or fusion more dangerous?
Is fission or fusion more dangerous? In 2019, National Geographic described nuclear fusion as the “holy grail for the future of nuclear power.” Not only would it produce more energy more safely, it would also produce far less harmful radioactive waste than fission, from which weapons-grade material in spent fuel rods taking millions of years […]
