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 […]
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 […]
Is the moon dying?
Is the moon dying? The moon isn’t “dead” after all. Newly discovered ridges on the moon’s surface are leading scientists to think that the moon might have an active tectonic system. These ridges, speckled with boulders, could be evidence that, not too long ago, tectonic activity broke apart the moon’s surface. Is Moon cracked? In […]
How many types of flux does a transformer have?
How many types of flux does a transformer have? There are basically two main types of transformers step-up transformer which converts a low input voltage into high output voltage and step-down transformer which converts high input voltage to low voltage. Transformers are used for regulating AC current, rectification, battery charging, etc. How can flux leakage […]
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 […]
Is GDP a good measure of the economy?
Is GDP a good measure of the economy? GDP is an accurate indicator of the size of an economy and the GDP growth rate is probably the single best indicator of economic growth, while GDP per capita has a close correlation with the trend in living standards over time. What are the 4 main limitations […]
What type of relationship exists between the length of wire in the resistance if all other factors remain the same?
What type of relationship exists between the length of wire in the resistance if all other factors remain the same? What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same? Resistance is directly related to length. What type of relationship exists between the length […]
