Why does oxygen production stop without light? Plants produce oxygen as a waste product of making sugar using sunlight, carbon dioxide, and water. If a plant needs energy, but doesn’t have sunlight, then it can burn the sugar that it made back when it had sunlight, and doing so requires oxygen. What is an important […]
Is breathing completely involuntary?

The breathing muscles are controlled automatically from the brainstem during normal breathing but can also be controlled voluntarily from the motor cortex. What is the structure of a […]
What sound frequency travels the farthest?
What sound frequency travels the farthest? In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium. Does bass travel up or down? In short, sound is omnidirectional, meaning that it can travel in all directions, including up and down. So, as you can see, while […]

Is height positive or negative?
Is height positive or negative? An object’s height is a property of that object and has nothing whatsoever to do with the object’s motion. It’s correct to speak of the object’s displacement when describing motion. “Negative height” is always a meaningless term. Without specifying a coordinate system, “negative displacement” is almost as useless. Can work […]
