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
