You discover a pattern of a 20 amino acid sequence at the C-terminus of over 50 proteins in an organism. You hypothesize that this amino acid sequence is a signal sequence for localization into a specific organelle or cell compartment, but you don't know which one. How might you use microscopy to investigate the location of proteins with this unique C-terminus sequence?

Which of the following is not a way in which a vascular plant's xylem and phloem are similar?

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.

Aprocedure done under controlled conditions to test a hypothesis is an inquiry.
