Switzerland, the USA, England […]
What was soccer first?
What was soccer first? association football What came first football or soccer? To most of the rest of the world, (including England, the birthplace of the modern sport,) it’s football. But what most people don’t know is that the word “soccer” is not in fact an American invention. On the contrary, it was an import […]
Which is the basic unit of matter?
Which is the basic unit of matter? In turn, the atom is the fundamental unit of matter…, that is, of an element. The number of positively charged protons and neutral neutrons in an atomic nucleus account for most of the mass of an atom. Each negatively charged electron that orbits a nucleus is about 1/2000th […]
What type of reaction forms disulfide bonds?
What type of reaction forms disulfide bonds? Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative folding. The other sulfur-containing amino acid, methionine, cannot form disulfide bonds. How are disulfide bonds broken? Disulfide bonds can be broken by addition of reducing agents. The most common agents […]
How do particles behave in solid?
How do particles behave in solid? Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the […]
What is an example of a positive mutation?
What is an example of a positive mutation? Quick Points. Mutations are changes in the DNA of an organism. Mutations can be beneficial, benign, or malignant, depending on where in the genetic code they are located. Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision. What is the most harmful mutation? 1). […]
Is E coli a vector-borne disease?
Is E coli a vector-borne disease? Flies can carry diseases such as typhoid fever, cholera, and dysentery. Cockroaches can carry diseases such as Escherichia coli (E. Coli), and Salmonella food poisoning. Rats and mice can carry diseases such as rat-bite fever, leptospirosis, and Salmonella food poisoning. Can humans be vectors of disease? Many factors affect […]
How much heat and pressure is needed for fusion?
How much heat and pressure is needed for fusion? Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core). At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about. […]
Why Hall voltage is negative?
Why Hall voltage is negative? In metals, the Hall voltages are generally negative, indicating that the electric current is composed of moving negative charges, or electrons. What is the value of Hall coefficient? The average value of the Hall coefficient was measured to be 0.0113±0.0002m3C−1 and sign of the Hall coefficient was positive corresponding to […]
Can a vector have a negative direction?
Can a vector have a negative direction? Vectors having the same length as a particular vector but in the opposite direction are called negative vectors. The magnitude, or length, of a vector, cannot be negative; it can be either be zero or positive. The negative sign is used here to indicate that the vector has […]
