Which type of scanner uses X-rays, and why?
A. Bar-code scanners, because X-rays are low-energy waves, making
it safe for the machine operators
B. Bar-code scanners, because X-rays produce a pattern of reflected
light when they shine on a pattern of black-and-white images
C. Security baggage scanners, because X-rays either pass through or
are absorbed by the objects in the baggage, creating an image of
the objects
D. Computer scanners, because X-rays release electrons via the
photoelectric effect

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
