Ahypothetical organ has the following functional requirements: (1) the ability to resist surface abrasion and mechanical stresses; (2) the ability to contract involuntarily when stimulated by cells of the nervous system; and (3) the ability to resist tension in many different planes of force. the organ needs one tissue to carry out each of these requirements, and it also needs one tissue to “glue” all other tissues together, and one tissue to stimulate the contracting cells. what are the five tissues that will make up this hypothetical organ? justify your choices.

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.
