How many vertebrae can be fused together? Two vertebrae need to be fused to stop […]
How do you calculate cross sectional area?
How do you calculate cross sectional area? Cross-sectional area is determined by squaring the radius and then multiplying by 3.14. For example, if a tree is measured as 10” DBH, the radius is 5”. Multiplying 5 by 5 equals 25, which when multiplied by 3.14 equals 78.5. Thus, the cross-sectional area of a 10” DBH […]
How does concave lens work?
How does concave lens work? A concave lens is thinner at the centre than at the edges. Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear […]

How does a fridge transfer energy?
How does a fridge transfer energy? A refrigerator transfers thermal energy from the cool air inside the refrigerator to the warm air in the kitchen. Thermal energy normally moves from a warmer area to a cooler area, so a refrigerator must do work to reverse the normal direction of heat flow. What type of energy […]

What are some common intercellular receptors? There are many kinds of cell-surface receptors, […]
Is twinkling of stars an illusion?
Is twinkling of stars an illusion? It’s not an optical illusion. When you’re stargazing, stars often do appear to be twinkling, and it’s Earth’s atmosphere that’s to blame.
