Thanks.
1. Consider the regulation of sodium levels in an animal. If Na+ levels begin to increase, which of the following responses might be seen?
i. increased Na+ influx ii. decreased Na+ influx
iii. increased Na+ efflux iv. decreased Na+ efflux
a. i and iii
b. i and iv
c. ii and iii ←
d. ii and iv
e. None of the above.

I have never seen this yet in my books, that can't be good, where did you get this question?
it's b or c though fo sho

It's c for sure. If ya think about it, when the sodium levels get too high in the body what will it do? It'll want to maintain stability (homeostasis). So to maintain homeostasis because of this increase in sodium, it'll decrease the influx of sodium (sodium goin inside the body) and increase the efflux (the sodium going out of the body). Good question though cuz it can ask you what process is occurrin n such. Like they can easily connect it to likea hypertonic hypotonic question business...ugh is it bad when you can start thinking up questions yourself? lol :'[

Hey I got it from a friend of mine. Do you think the DAT has this type of questions? gosh, i'll be dead....

thanks... i was thinking the other way around...

doc, you like this type of questions? want me to type it up?

 

[doc3232]

Don't do it if it won't help you also.
and if you do type them up, don't up the answers (no choices), let people come up with the answers themselves. leaves more from for creativity 🙂🙂

is this depolarization problem?

the question seems to be poorly worded. It can either be within the nerves (outside/inside membrane) or even in the loop of henle (descending/ascending)...

but i guess this is an extremely easy version of question to throw people off...

High ingestion of Na+ --> Homeostasis must balance it....so efflux (exit) of Na+ will obviosuly increase while influx (entry) of Na+ will decrease....This question probably tested people whether they know "efflux" and "influx"
