Does NYC meet the criteria as being a "livable" city? Why or why not? and if there is any room for improvement? Why or why not? **Note** The world's most livable cities are not those with "perfect" auto access between all points. Instead, they're cities that have taken measures to reduce outward sprawl, diminish automobile tr

Why are most neurons GABAergic? What are the advantages to have GABA neurons in motor systems? Thank you.
How would you create a city that does not produce more air pollution than the atmosphere can cleanse naturally? In creating this more sustainable environment, consider livability, safety, and convenience. Consider this as your personal game of Sim City. How do you design a city that does not produce more air pollution than th

An investigation into the kidney's homeostatic functions Introduction The kidneys contribute to the regulation of the water and electrolyte balance and the acid-base status of the body through hormonal influence on renal activities. There is a wide variation between individuals in the formation of urine, in any one individ
Eight years ago the doctor asked if we wanted to save (can't remember if it was to froze or not) the blood from the umbilical cord from our daughter. His explanation was that it was full of good stuff and we could save it. Here is my question: How long can the stuff in the umbilical cord be saved for? Are there any def
The stem cells are captured from embryonic cells, but they also can be captured from the placenta and umbilical cord. a. If this is the case, why is there so much controversy on the subject? (It is not unethical after all to capture stem cells from the placenta or umbilical cord after the birth of a child). b. Also,
What would happen if a person was intravenously injected with distilled water instead of isotonic saline? And how would haemolysis rates change of a person who hand sickle cell disease?
I have been reading a lot about fibromyalgia lately and in a book by a Dr. Amand, as reported by a couple of Drs. 25 years ago - states that calcium remains immobile due to a lack of Action potentials because people with FMS have a 25% drop of ATP levels in their muscle thus not allowing calcium to be moved via active transport.
Trying to figure something out-if there were an excess of Calcium due to Action potentials stopping for some reason, what, if anything would prevent calcitonin from lowering the level? Is there anything else responsible for lowering calcium? What would happen if the calcium just stayed in one placed unchecked-lumps/bumps??
Insulin _ What is it ? What are it's advantages and disadvantages in the use of diabetes? Is it the most current effective treatment toady?
Why is osmosis important to proper kidney functioning? Include how osmosis is related to nephron physiology. How does the nephron perform filtration, reabsorption and tubular secretion? What are some examples of "water following salt." These areas are encompassed.
How do negative feedback mechanisms contribute to homeostasis? What are some examples in terms of temperature regulation and blood pressure maintenance? What would happen if temperature regulation were suddenly controlled by a positive feedback loop? These questions are pondered.
The vital signs include (a) temperature (b) heart rate (c) respiratory rate (d) reflex activity (More than one or none may be true)
Using the lab values given, determine if the patient is in alkalosis or acidosis, if it is metabolic or respiratory and if it is being compensated for. Give specific reasons for your answers. pH = 7.5; PCO2 = 24 mm Hg; HCO3- = 18 mEq/L
Long term diabetics experience kidney failure which leads to anemia. How does kidney failure correlate to anemia?
In a lab strain of Drosophila, cinnabar (cn) and brown (bw) are recessive eye colour mutations known to be 41 m.u. apart on chromosome 2. When similar mutant alleles were induced in a strain from nature, the same linkage of cn and bw was observed. However, when a wild-type strain from nature was crossed with a cn bw/cn bw lab st
