You are interested in studying the secretion of the growth factor bdnf by neurons, and you want to track bdnf from its synthesis on ribosomes through secretion by cells. you hypothesize that (i) bdnf transits through the endomembrane system; (ii) is packaged into secretory vesicles and actively transported to the plasma membrane; and (iii) bdnf-containing vesicles fuse with the membrane when local ca2+ concentrations increase. propose an experiment that addresses each part of this hypothesis. in doing so, specifically state (i) the organelles of the endomembrane system that you would expect bdnf to travel through; (ii) the type of vesicle into which bdnf is packaged, as well as any motor protein(s) and/or cytoskeletal structures required to the bdnf-containing vesicle to the plasma membrane; and (iii) describe the ca2+-dependent mechanism through which you think vesicular fusion is regulated. for each part of the hypothesis, note two proteins that you might target (either by pharmacological or genetic approaches) to determine whether those processes are required for secretion of bdnf. state the expected outcome of your proposed experiment for each part of the hypothesis, based on targeting these proteins.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.  

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
