Listed in the Item Bank are some key terms and expressions associated with the categories seen in the Venn Diagram. To find out more information about items, some have more details available when you click on them. Drag and drop each item onto the proper area of the diagram. If an item describes more
than one category, be sure to place it in the overlapping space.
Viruses are tiny infectious pathogens that cause many different diseases, such as polio, and the flu.
Though they are similar to one celled organisms in some ways, in many ways they are very different.
Use the venn diagram below to show the similarities and differences between viruses and living organisms.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i. e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
