Which disease is the result of somatic mutation? Somatic mutations can give rise to cancer (9), as well as noncancerous diseases. Noncancerous somatic mutations that occur during development may affect cell proliferation, as would be the case in cancer, or they may simply alter cellular function without causing a proliferative effect. What causes somatic mutation? […]
What is the electric potential at the halfway point between the two charges?
What is the electric potential at the halfway point between the two charges? At the midpoint between the charges, the electric potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero. At what point or points on the is the electric potential zero? PROBLEM […]
What is a vector vector example?
What is a vector vector example? A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. What is called a vector give one example? […]
What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits?
What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits? What happens to the pattern if we try to determine which slit the electron goes through by using a laser placed directly behind the slits? If the rate of electrons […]
What are the five characteristics of ionic compounds?
What are the five characteristics of ionic compounds? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. How can you […]
What happens when entropy decreases?
What happens when entropy decreases? The total entropy of a system either increases or remains constant in any process; it never decreases. For example, heat transfer cannot occur spontaneously from cold to hot, because entropy would decrease. Entropy is very different from energy. Entropy is not conserved but increases in all real processes. What causes […]
Is the relationship between frequency and wavelength direct?
Is the relationship between frequency and wavelength direct? Wavelength (typically measured in nanometers) is the distance between two points in a wave. Frequency and wavelength have both direct and inverse relationships. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. Is frequency and energy directly […]
At what age are people most physically active?
At what age are people most physically active? Age The age group 18 to 44 was the most likely to exercise. Of those individuals age 18 to 44, 59.7 percent reported exercising at least three times a week for half an hour or more. This compares with 53.5 percent and 46.7 percent, respectively, for the […]
Is thermal energy the total kinetic energy of an object?
Is thermal energy the total kinetic energy of an object? Thermal energy is the total internal kinetic energy of an object due to the random motion of its atoms and molecules. It is sometimes confused with internal energy or thermodynamic energy. They consist of the sum of the internal kinetic energy (thermal energy) and the […]
What is the power of an appliance?
What is the power of an appliance? The power of an electrical appliance tells us how much electrical energy it transfers in a second. Power, P is measured in watts (W) where: 1 W = 1 J/s (joule/second). Appliances used for heating have a much higher rating than those used to produce light or sound. […]
