What does labeled probe mean? A probe is a piece of DNA identical (or very similar) to a sequence of interest. In order to locate a specific DNA sequence by hybridization, the probe is labeled with a reporter group. coli DNA polymerase is used to make a labeled probe. What are the methods of Labelling? […]
What is the rate at which work is done or energy is transferred?
What is the rate at which work is done or energy is transferred? power: A measure of the rate of doing work or transferring energy. watt: In the International System of Units, the derived unit of power; the power of a system in which one joule of energy is transferred per second. How many joules […]
Is a device that converts digital information into analog and vice versa?
Is a device that converts digital information into analog and vice versa? Modem used to converts digital signals to analog signals. What do you call a device that converts digital signal to analog signal and vice versa? Devices that convert digital signals to analog are called DAC. Why do we need to convert digital to […]
Why is it called the factor label method?
Why is it called the factor label method? In both fractions, the numerator and denominator are equal quantities. Thus, these two fractions equal one another and both are equal to 1. The name of the factor label method game is to multiply the value you are given, unit of measurement included, by the conversion factor […]
Why is kinetic energy proportional to v2?
Why is kinetic energy proportional to v2? Hence, the proportionality of KE to v^2 comes from the consideration that changes in kinetic energy should be directly proportional to the work done on an object. How does mass affect velocity down a ramp? Weight affects speed down the ramp (the pull of gravity), but it’s the […]
What is a real life example of scientific notation?
What is a real life example of scientific notation? For example, the $65,000,000,000 cost of Hurricane Sandy is written in scientific notation as \begin{align*}\$6.5 \times 10^{10}\end{align*}. Why is scientific notation important? You’re less likely to make mistakes reading or writing very big and very small numbers if you use scientific notation. How do you write […]
Why is normal distribution important?
Why is normal distribution important? The normal distribution is the most important probability distribution in statistics because it fits many natural phenomena. For example, heights, blood pressure, measurement error, and IQ scores follow the normal distribution. It is also known as the Gaussian distribution and the bell curve. What causes a normal distribution? The normal […]
What causes heavy dew in the morning?
What causes heavy dew in the morning? Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation […]
Which of the following is a postulate of the kinetic molecular theory?
Which of the following is a postulate of the kinetic molecular theory? As applied to gases, the kinetic molecular theory has the following postulates: Gases are composed of very tiny particles (molecules). The actual volume of these molecules is so small as to be negligible compared with the total volume of the gas sample. A […]
How many atoms of fluorine are in?
How many atoms of fluorine are in? 1.9×10-6 gram of fluorine have atoms =6.022×1023×(1.9×10-6g)(19.0g)=6.022×1016 atoms. How many molecules are in 1.50 moles of fluorine gas? Explanation: Recall that moles can be converted to particles using Avogadro’s constant ( 6.022⋅1023 ) which is the number of molecules per mole of a substance. In 1.5 moles of […]
