Textbook?

[webCHO]

Essentials of human anatomy and physiology by Elaine N. Marieb is my book

[mith]

no, I mean have you tried looking for the answers in there?

[webCHO]

yes, I spent hours and hours reading through.

[mith]

It's not how many hours it's how closely you read...for example #1, only one product is actually excreted, everything else that comes out from the glomerules gets reabsorbed back.

[webCHO]

so the answer is...??

[canalon]

so the answer is...??

...in your f#$%ing textbook! Didn,t you get the message? Go study for yourself we don't do YOUR homework for you.

[webCHO]

this isn't homework, this is a test. i thought this was a community that is all about contributing. If you know one of the answers, contribute. If not, don't bother posting because you're not contributing anything useful to the community.

[kjle]

lol, whoa! nice to see some emotion, I feel for you mods having to put up with this like 8 times a day

[canalon]

Test or not it is the same. We are not promoting laziness but learning That means that you search first and if you have dubt you come with your answers and your doubts and we will help. e are not just providing answer. This the way this community works, and mind you that is the way the moderator want it to work and oh oopps I belong to this group. Too bad... So go to work.

You can stop posting on this topic because you are not providing any useful information that can be used by me or anyone else for that matter.

Allow me to paint the larger picture for you my friend - My questions added content. Content draws in traffic (hits to this website). Traffic draws in all types of people, educated or not. Higher traffic = more people clicking on the google ads on this website which makes the owners money.

I can care less about your personal opinions or your "high horse" moderator level. Because in the end, it's all about money. Now answer my questions if you can. Build content for this website if you will, otherwise, stop posting under this topic. Your input is not useful.

Have a nice day.
