What properties does Silicon share with carbon that would make silicon based life more likely than say neon based life or aluminum based life? Si has four valence electrons, the same number as carbon. Therefore, silicon would be able to form long chains, including branches, that could act as skeletons for organic molecules. It would […]

Can mushrooms upset your tummy? Mushrooms – Like the “musical fruit,” mushrooms contain the oligosaccharide sugar raffinose which can contribute to digestive issues. Like most things, portion control is the main goal. So try small amounts of cooked mushrooms and see if your stomach is less sensitive. Can cooked mushrooms cause diarrhea? Although some people […]

What are Airy functions used for? The Airy function is the solution to time-independent Schrödinger equation for a particle confined within a triangular potential well and for a particle in a one-dimensional constant force field. What is Aries equation? The general form of a homogeneous second order linear differential equation looks as follows: y”+p(t) y’+q(t) […]

What is the best way to overcome imagined risks? Replace negative self-talk with positive self-talk is the best way to overcome imagined risks. Replace negative self-talk with positive self-talk is the best way to overcome imagined risks. When you complete a job but use it? When you complete a job, but use more time and […]

Why does a flashlight need two batteries? Using two batteries instead of one should have made the light shine brighter. This is because you provided more voltage to the circuit and thus more current. More current means more electrons are flowing into the filament. Subsequently, more energy is being emitted, or released, in the form […]

Why do pigeons nod their head? Pigeons’ eyes cannot focus as quickly as ours. The ‘nodding’ is actually a way of making the head stay still for longer in order to allow the eyes to focus. Why do pigeons bob their heads while they walk? Birds, like chickens and pigeons, bob their heads so the […]

What happens to the ear drum as sound gets louder? The sound waves travel through the ear canal to reach the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones amplify, or increase, the sound vibrations and send them to the […]

What happened to ancestral Puebloans? For more than 700 years they and their descendants lived and flourished here, eventually building elaborate stone communities in the sheltered alcoves of the canyon walls. Then, in the late A.D. 1200s, in the span of a generation or two, they left their homes and moved away. What was the […]

What is the only form of nitrogen that non legume plants can take in and use? Nevertheless, plants cannot directly access dinitrogen gas, which makes up about 80 % of the atmosphere. Plants absorb the available nitrogen in the soil through their roots in the form of ammonium and nitrates. What are the 4 major […]

What is correlation in rock layers? Correlation is the technique of piecing together information from widely separated rock outcrops in order to create an accurate chronological profile of an entire geologic time period. In order to accomplish this, geologists attempt to measure the absolute ages of rock strata using techniques such… Why are some rock […]
