When two variables decrease Together they are? Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases. How do you find the relationship between […]
Is RNA the same as DNA?
Is RNA the same as DNA? There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine. What is RNA and function? The […]
What is the Mid Atlantic Ridge and why is it important?
What is the Mid Atlantic Ridge and why is it important? Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a “spreading center” or a “divergent plate boundary.” The plates spread […]
What are the 3 scientific attitudes?
What are the 3 scientific attitudes? In summary, the scientific attitude is composed of 3 main ideas: curiosity, skepticism, and humility.

What happens if you force magnets together?
What happens if you force magnets together? In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will […]

How many molecules are in a mole? The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol. What is silica composed of? Silica (quartz): Silica, SiO2, is a chemical compound that is composed of one silicon atom and two oxygen atoms. It appears naturally in several crystalline forms, one of […]

Are rainbows at night rare?
Are rainbows at night rare? The moon is the key, just as sunlight produces rainbows during the day, moonlight can produce rainbows at night. Moonbows are rare because moonlight is not very bright. A bright moon near to full is needed, it must be raining opposite the moon, the sky must be dark and the […]
What rollercoaster has the longest drop?
What rollercoaster has the longest drop? Kingda Ka How do drop towers slow down? And as Lenz’s law states, that magnetic field opposes the motion of the magnets. As a result, the magnetic field pushes up against the seat, causing the cart to slow down. This is how a drop tower ride’s magnetic brakes work. […]
