What color that makes Brown? Brown is a composite color. In the CMYK color model used in printing or painting, brown is made by combining red, black, and yellow, or red, yellow, and blue. In the RGB color model used to project colors onto television screens and computer monitors, brown is made by combining red […]

What happens when air subsides? Subsidence, or sinking of air, may happen instead, forming an area of high pressure, an anticyclone. Large scale subsidence occurs when air several thousands of feet overhead is denser than the surrounding air. Warming of the air as it subsides increases evaporation, causing clear skies. Does cold air have a […]

Is Pluto seismically active? You don’t have to be a planet to have tectonics: Pluto is currently geologically active. Data from NASA’s New Horizons spacecraft when it flew through the Pluto system in 2014 revealed a complex set of geological features, including faults. Why is Pluto active? Pluto may still be tectonically active because that […]

Is body size a life history trait? Some life history traits include the size of an animal at birth (or at hatching), the age and size at which an animal reaches reproductive maturity, how it reproduces (oviparous or viviparous), how often it can reproduce (semelparous or iteroparous), the length of time it is reproductively active, […]

What are two unique features of the stratosphere? The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere. Polar stratospheric clouds (PSCs) are the exception. PSCs appear in the lower stratosphere near the poles […]

Is Y =- 5 a linear equation? No. All linear functions can be written in the form y = mx + b, where m is the slope and b is the y-intercept (slope-intercept form). This function, y = 5/x, is a hyperbola, with a vertical asymptote at x = 0 and horizontal asymptote at y […]

How is 2 2×4 equal 10? Apparently 2+2×4=10 because you always x before + This is news to me. The way I was taught, sums are read left to right unless ( ) tell you to do that bit first. So for 10 the sum should be 2+(2×4)=10 Otherwise 2+2=4 then 4×4=16 Have I been […]

What are the key concepts in the evolution theory of Darwin? Branching descent and natural selection are the two key concepts of Darwinian Theory of Evolution. Why was Lamarck’s theory wrong quizlet? LaMarck’s theory was incorrect because he did not know how traits were inherited & that the organism’ behavior has no effect on inherited […]
