Can you please answer the question as posted a through i do not have to be long explanations is really to check my answers. I have already posted it and somebody answered it wrong. If you dont know how to answer please let other that understand the question do, this way I dont have to re post and waste my questions. I will give you a good review if you answer the question accordingly.

a) Is the extensive property NGF?

b) please draw the difference in b and c (clearly show the drawing)

c) I think is continuous because the NGF is being administered and monitored over an undefined time period but I am not sure, is it correct?

d) I think is open because NGF is leaving the system with bulk material being exchanged in the metabolic processes but again not sure please explain

e) dynamic, NGF is changing over time

f) No reaction is happening but again not sure please confirm

g) I think yes because NGF is leaving due to metabolic processes which is basically energy leaving the system but again not sure

h) in - out + gen - cons = acc

in =0 cons =0

gen = 0.32 g NGF/day. con= 0.11 g NGF/day out =0.022 g NGF/day

0 - 0.022 + 0.32 - 0.11 = 0.188

i) acc = 0.188

j) I have no clue

Never growth factor (NGF) has been shown to have trophic effects on some cholinergic systems in the brain. Since it helps prevents neurons form dying, work has been done to see if NGF is viable as a therapeutic agent in the treatment of Alzheimer's disease. One treatment involves fabricating polymers into porous implants loaded with NGF power and surgically placing them within the brain. It has been determined experimentally that the polymer implant used in treating Alzheimer's disease can release 0.32gNGF/day. In the brain, 0.11gNGF/ day is eliminated due the metabolic process, and 0.022gNGF/day is lost due to non-specific binding. a. Name the extensive property being counted. b. Draw a picture of the system. Labeling the system, boundary, and surroundings. c. Is the time period continuous or discrete and explain why. If it is discrete what is the length of time examined? d. Identify the system as open, close, or isolated and explain why. e. Identify the system as steady-state or dynamic and explain why. f. Identify whether the system has a reaction (Yes, No, N/A). Explain why. g. Identify whether the system has any energy interconversions (Yes, No, N/A). Explain why. h. Write the general accounting equation (algebraic, differential, integral) to track NGF. Which (if any) terms can be eliminated? i. What is the rate of accumulation of NGF in the brain? j. Neurons do not exhibit any reaction to NGF until the concentration in the brain reaches 6.2ng/mL. How long does it take before a therapeutic level is achieved? Assume you only want to treat the diseased part of the brain which has a volume of 500cm3
