What are some examples of seafloor spreading? Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate. What is used to measure bathymetry? ADCPs measure water velocity by transmitting […]
What happens when air resistance is increased?
What happens when air resistance is increased? The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. The object is […]
Does smoking change sperm DNA?
Does smoking change sperm DNA? How does smoking affect sperm? Men who smoke have decreased sperm concentration, decreased motility (how sperm swim), fewer normally shaped sperm, and increased sperm DNA damage. Do cigarettes alter your DNA? While we’ve long known that smoking is linked to cancer, this new research allows scientists to quantify the molecular […]
