Calculate the flux and the rate of removal of urea at steady-state in g/h from blood in a cellophane membrane dialyzer at 37oc. membrane thickness is 0.025 mm thick and has an area of 2m2. the mass transfer coefficient on the blood side is estimated as kc1=1.25x10-5 m/s and on the aqueous side is 3.33x10-5m/s. the permeance of the membrane is 8.73x10-6 m/s. the concentration of urea in blood is 0.02 g urea/100ml and in the dialyzing fluid urea concentration is assumed to be 0.

Epinephrine is a hormone released from the adrenal gland of the body, most often in a stressful situation. it is known as the "fight-or-flight" hormone. one way that it causes a response in the body is to activate receptors on muscle cells. where are these cellular receptors located? a. on the cell membrane b. in the nucleus c. on the cell wall d. around the mitochondria

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
