You will also hear people say “How can I help you?” To the punctilious, “may” is preferable to “can,” but both expressions are gracious and acceptable, much better than “Whassup?” How […]
Which biogeochemical cycles are key to life?
Which biogeochemical cycles are key to life? The nitrogen cycle is another biogeochemical cycle critical to life (Fig. 6.10). Nitrogen is especially important to ecosystem dynamics because many ecosystem processes, such as primary production and decomposition, are limited by the available supply of nitrogen.

How does electricity flow in a circuit draw an open circuit?
How does electricity flow in a circuit draw an open circuit? The electric circuit in which there is a gap in the connections between the terminals of the cell, wires and the bulb, etc is called an open circuit (or incomplete circuit). Electricity does not flow through an open circuit because there is a gap […]

What are two major differences between prokaryotic bacterial and eukaryotic protist cells?
What are two major differences between prokaryotic bacterial and eukaryotic protist cells? Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. What are the three most common types of […]

Solar radiation includes visible light, ultraviolet light, infrared, radio waves, […]
Which object will not be attracted to the magnet?
Which object will not be attracted to the magnet? Metals that have iron in them attract magnets well. Steel is one. Metals like brass, copper, zinc and aluminum are not attracted to magnets. Non-magnetic materials such as wood and glass are not attracted to magnets as they do not have magnetic materials in them. Which […]
