Which waves can carry information? While many different types of EMF are used to convey information over distance, the most common are radio waves, also called radiofrequencies. This is a wide spectrum ranging from tens of kilohertz to 300 gigahertz. Within this spectrum, frequency bands are allocated to each use. How do we use waves? […]
How do we digest starch?
How do we digest starch? Starch breaks down to shorter glucose chains. This process starts in the mouth with salivary amylase. The process slows in the stomach and then goes into overdrive in the small intestines. The short glucose chains are broken down to maltose and then to glucose. Which organ is primarily responsible for […]
Where is the potential energy of the system the greatest?
Where is the potential energy of the system the greatest? Where is the potential energy of the system the greatest? At the highest point of the oscillation. At the new equilibrium position of the oscillation. Is potential energy negative or positive? This is a negative value for two reasons; the force acting between them is […]

What is the functionalist theory in sociology?
What is the functionalist theory in sociology? The functionalist perspective sees society as a complex system whose parts work together to promote solidarity and stability. This approach looks at society through a macro-level orientation and broadly focuses on the social structures that shape society as a whole. Why is functionalist perspective important? Functionalism emphasizes the […]
Why did Rutherford conclude?
Why did Rutherford conclude? Rutherford deduced that the atomic nucleus was positively charged because the alpha particles that he fired at the metal foils were positively charged, and like charges repel. He also concluded that the electrons orbit the nucleus like the planets orbit the sun. Is gold leaf one atom thick? And doing a […]
How do you determine phenotype?
How do you determine phenotype? The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes. What are the different […]

Why heating an air parcel causes it to rise?
Why heating an air parcel causes it to rise? Warm air rises primarily due its lower density as compared to cooler air. As the temperature increases, the density of the air decreases. As the denser air reaches the earth’s surface it spreads and undercuts the less dense air which, in turn, forces the less dense […]
What solutions are there to global warming?
What solutions are there to global warming? For example, improvements to energy efficiency and vehicle fuel economy, increases in wind and solar power, biofuels from organic waste, setting a price on carbon, and protecting forests are all potent ways to reduce the amount of carbon dioxide and other gases trapping heat on the planet. Are […]
