Is the independent variable the control? An independent variable is the variable the experimenter controls. Basically, it is the component you choose to change in an experiment. This variable is not dependent on any other variables. Is the control group the independent variable? The independent variable is “controlled” or held constant in the control group. […]
What is the difference between bottom up and top down processing?
What is the difference between bottom up and top down processing? Bottom-up processing begins with the retrieval of sensory information from our external environment to build perceptions based on the current input of sensory information. Top-down processing is the interpretation of incoming information based on prior knowledge, experiences, and expectations. Can we sense without perceiving? […]
What do you mean by average speed the odometer of a car reads 2000 km at the start of a trip and 2400 km at the end of the trip .if the trip took 8 h calculate the average speed of the car in KM hour?
Why agarose gel is used for DNA?
Why agarose gel is used for DNA? Agarose gel electrophoresis is used to resolve DNA fragments on the basis of their molecular weight. Smaller fragments migrate faster than larger ones; the distance migrated on the gel varies inversely with the logarithm of the molecular weight. How does agarose gel separate DNA? To separate DNA using […]
What is the wavelength of a wave What are some possible units?
What is the wavelength of a wave What are some possible units? Wavelength is usually measured in meters (m). Frequency is the number of cycles of a wave to pass some point in a second. The units of frequency are thus cycles per second, or Hertz (Hz). What is standard wavelength unit? meter Is Angstrom […]
Can hydrogen be used to fill balloons?
Can hydrogen be used to fill balloons? Hydrogen is another gas lighter than air; it’s even lighter than helium. Hydrogen, however, is not used in balloons and this demonstration shows why. Helium is a special gas called a Noble Gas, which means it doesn’t burn. When a match is held near a helium-filled balloon, the […]

The narrator is caught in the conflict between these two worlds; her attempt to suppress her creative spirit in favor of John’s rationality leads to her mental breakdown. What is the […]
What are the three termination processes in free radical polymerization?
What are the three termination processes in free radical polymerization? The termination steps of free radical polymerization steps are of two types: recombination and disproportionation. In a recombination step, two growing chain radicals form a covalent bond in a single stable molecule. For the example of a vinyl polymer, ——-CH2–C°HX + ——-CH2–C°HX → ——-CH2–CH2X–CH2X–CH2——- What […]
How many grams are in 4 moles of oxygen?
How many grams are in 4 moles of oxygen? 128 g What is the formula for calculating moles? Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams. What is the mole equation? Avogadro’s number […]
