Why does a paddle with holes hurt more? The paddle might have holes in it,23 allowing it to move faster and therefore hurt more. One student noted, “It has holes in it, so the air can just woosh through.”24 Part or all of the paddle can be covered with duct tape to prevent the wood […]
In what way does taste aversion violate the principles of classical conditioning?
In what way does taste aversion violate the principles of classical conditioning? A conditioned taste aversion involves the avoidance of a certain food following a period of illness after consuming that food. These aversions are a great example of how classical conditioning can result in changes in behavior, even after only one incidence of feeling […]
How do you find the dependent variable in research?
How do you find the dependent variable in research? Which Variable Does the Experimenter Manipulate? One way to help identify the dependent variable is to remember that it depends on the independent variable. When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable. Is it possible to […]
How long would it take humans to travel a light-year?
How long would it take humans to travel a light-year? This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year. Do […]
What are the major criteria for selecting a site for power generation from geothermal energy?
What are the major criteria for selecting a site for power generation from geothermal energy? Site selection criteria rely on conditions such as distance to cold water pumping, bathymetry, thermal difference (not less than 20°C), and social and environmental aspects. Why are geothermal power plants clean sources of electricity? Using geothermal energy is relatively clean. […]
How long does it take for a 1000 mL IV drip saline bag to empty?
How gamma rays are used in medicine?
How gamma rays are used in medicine? Gamma rays are high energy electromagnetic waves which are only stopped by thick lead. This means they can easily pass through medical equipment, such as syringes. As gamma rays pass through the packaging and syringe, they will kill viruses and bacteria which contaminate the syringe. How do doctors […]

Why interphase between meiosis I and meiosis II is short?
Why interphase between meiosis I and meiosis II is short? First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II […]
What electromagnetic wave is harmful to humans?
What electromagnetic wave is harmful to humans? Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation poisoning. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. […]
