Suppose you are studying a mutant strain of mice, called wimpy, that displays excessive submissive behavior. After extensive genetic crosses and mapping, you now think that you have zeroed in on the gene to which the wimpy mutation probably maps. To expedite your investigations you' re going to have to make some educated guesses about the structure and cell biology of the protein. Due to homology with other genes you tentatively assume that this protein is a cell surface receptor and that segment 1 is a cleaved ER signal signal sequence. Required:
Draw the most likely topology of the protein in the plasma membrane.

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.

If you have a difficult time knowing where your hand is without looking at it you may be having a problem with your what ?

Describe your dna model. which part do the straws represent? the pushpins? the paper clips and the black dots you made with the marker?
