Answer: The sodium-potassium pump system moves sodium and potassium ions against large concentration gradients. It moves two potassium ions into the cell where potassium levels are high, and pumps three sodium ions out of the cell and into the extracellular fluid.
Explanation:
This is a very easy paragraph analysis question. The answer is c. "Over time, scientific knowledge is reevaluated and extended through new scientific research." The reason why the answer is C., is because the chronological order of the study of genetics is as follows:
- Mendel does his pea plants experiments, but did not know how traits were passed to the offspring.
- Avery concludes that DNA is the "material" that passes on traits to the offspring, probably using Mendel's research and his own research (pneuonimia virus research) as well.
- Since the existence of DNA was published, Watson and Crick used it to identify an accurate model of the structure of DNA, using the four bases: cytosine, adenine, guanine, and thymine.
Overall, we see a trend of scientists publishing results based on what scientists did before.
The nurse found a transitory
short and long term memory loss and confusion. Electroconvulsive therapy is a kind of a
procedure that done under general anesthesia,
this procedure can changes the brain chemistry by giving the patient a
small electric current that will pass through the brain intentionally making a
small fast seizure. That’s why there are some side effects is memory loss, some
memory problem improve after the treatment ends.
Ummmm…. can you elaborate on what it is ?
