How does heat transfer from one object to another? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
Why glass prisms bend and separate light?
Why glass prisms bend and separate light? The dispersion of colors in a prism occurs because of something called the refractive index of the glass. As the white light moves through the two faces of the prism, the different colors bend different amounts and in doing so spread out into a rainbow. What is the […]

What are three signs of the inflammatory response?
What are three signs of the inflammatory response? What are the signs of inflammation? The four cardinal signs of inflammation are redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor). Redness is caused by the dilation of small blood vessels in the area of injury. Does vitamin D help with inflammation? Beyond its critical […]

What are the three major earth cycles?
What are the three major earth cycles? The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life. What is Earth’s natural cycle? The […]
What is the main idea behind magnetic anomaly detectors?
What is the main idea behind magnetic anomaly detectors? A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth’s magnetic field. What did marine magnetic anomalies prove? These anomalies provided the convincing evidence for plate tectonics and the resulting revolution in the earth sciences. In addition to the intensity […]
What is a drawback of having an fMRI scan?
What is a drawback of having an fMRI scan? General disadvantages of the method For a non-invasive scan, fMRI has moderately good spatial resolution. However, the temporal response of the blood supply, which is the basis of fMRI, is poor relative to the electrical signals that define neuronal communication. What is the oldest brain imaging […]
