Sherman is a medical researcher trying to find the causitive agent of a very sick patient with a lung disease. he is fairly sure that the germ causing the illness is not a bacteria, because saliva samples from the patient have not grown any bacteria in the lab. he has also not seen any cells under the lab's basic microscope. all signs seem to be pointing towards the germ being a virus. to know for sure, sherman needs to see the germ under a microscope and determine its 3-dimensional shape. which type of microscope should sherman use to try to see the 3-dimensional shape of a virus in the patient's sample? a) light microscope b) stereomicroscope c) scanning electron microscope d) transmission electron microscope

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).

Were you able to observe the nucleolus in any of the cells if so which ones

Apopulation of rabbits live in a local forest. some had a mutation for a large body and long legs. the graph below shows the number of both the mutant and the normal rabbits over 5 generations. which of the following statements is true for this scenario? question 7 options: the rabbits with the mutation were more successful with restricted food than the normal rabbits. both sets of rabbits were equally successful with the restricted food source. i the normal rabbits were more successful with restricted food than the rabbits with the mutation. the graph does not let us know which rabbit was more successful.
