Where we can see Tyndall effect? Tyndall effect, also called Tyndall phenomenon, scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window. What is the dispersing medium in a colloid? A colloid is a heterogeneous mixture whose […]
What is action spectrum and absorption?
What is action spectrum and absorption? The absorption spectrum indicates the wavelengths of light absorbed by each pigment (e.g. chlorophyll) The action spectrum indicates the overall rate of photosynthesis at each wavelength of light. It is a graphical representation of the amount of light of different wavelengths absorbed by a pigment. Which pigments are most […]

What force keeps a bicycle wheel from flying off?
What force keeps a bicycle wheel from flying off? Another idea you should know about in order to understand a gyroscope is centripetal force. This is a force that pulls on an object that is spinning around another object and keeps it from flying off in a straight line. Why is a rotating bicycle wheel […]
How much activity is considered active?
What makes good insulation?
What makes good insulation? Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them. This makes them very good insulators because heat energy can’t flow through them. This stops the movement of air in the space between the two layers of glass and reduces heat loss from […]
What is an example of experimental control?
What is an example of experimental control? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. How do you show experimental […]
What are the problems with DNA evidence?
What are the problems with DNA evidence? DNA evidence is only as reliable as the procedures used to test it. If these procedures are sloppy, imprecise, or prioritize particular results over accuracy, then the so-called “DNA evidence” they produce cannot be a trustworthy basis for a conviction. What are the 4 basic steps of DNA […]
What are the 2 branches of the autonomic nervous system?
What are the 2 branches of the autonomic nervous system? The autonomic nervous system has two main divisions: Sympathetic. Parasympathetic. Can you control autonomic nervous system? While involuntary physiological processes are usually outside the realm of conscious control, evidence suggests that these processes, through regulation of the autonomic nervous system, can be voluntarily controlled. Is […]
Is liquid a good conductor of electricity?
Is liquid a good conductor of electricity? Substances which allow easy flow of electric current through them are known as electrical conductors. Metals, graphite and certain liquids are a few examples of good conductors of electricity. What liquids are non conductive? Pretty much any oil or organic liquid is non-conducting. These include: Mineral oil. What […]
