Is summer hotter in the Southern Hemisphere?
Is summer hotter in the Southern Hemisphere? One would think that southern hemisphere summers might be a little warmer. However, the southern hemisphere is predominantly water (the land/water ratio is 4/11). Water has a higher heat capacity than land, meaning that it requires more heat energy to increase its temperature than land needs. Is summer […]
Is velocity constant in free fall?
Is velocity constant in free fall? Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity. Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity […]
Which direction are new nucleotides added?
Which direction are new nucleotides added? DNA is always synthesized in the 5′-to-3′ direction, meaning that nucleotides are added only to the 3′ end of the growing strand. As shown in Figure 2, the 5′-phosphate group of the new nucleotide binds to the 3′-OH group of the last nucleotide of the growing strand. What is […]

Do we breathe nitrogen?
Do we breathe nitrogen? We actually breathe air. It contains many gases like nitrogen, oxygen, carbon dioxide and argon among many others. Although nitrogen is the largest component of the inhaled air, it is inert and has no effect on our body. And the air exhaled also contains nitrogen, oxygen, carbon dioxide etc. Is nitrogen […]
How do you find the slope in a graph?
How do you find the slope in a graph? Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or […]
How do we know the sun rotates?
How do we know the sun rotates? The Sun rotates once every 24 days at its equator, but only once every 35 near its poles. We know this by watching the motion of sunspots and other solar features move across the Sun. What would happen if the sun stopped rotating? The gravitational attraction of the […]
How does the image of a concave lens always appear?
How does the image of a concave lens always appear? Plane mirrors, convex mirrors, and diverging lenses will always produce an upright image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). 5. The image […]
