How is the Student Study Guide for Biology for the 7th edition of the Reece/Campbell textbook? ?

We Answered:

if you're taking an AP course, then i'm just going to say that it's only ok.. not as up to speed as my AP Bio course from before because it was not only based on the book but mostly on the teacher's notes and lectures.
just gives you a general idea of the chapter if you didn't read the chapter in the book but in terms of relating to the detailed info in the book, it's nice and has a lot of problems you can work with, it has answers in the back too.. if you order it from like half.com or amazon, it costs less than a dollar.

Help with a fill-in-the-blanks biology study guide that's DUETOMORROW!!!! Can you fill in the blanks please?

We Answered:

the digestive system...circulatory system...monosaccharides...alveoli/type I cells...circulatory system...circulatory system...blood/bloodstream?...CO2 and H2O...CO2...circulatory system...alveoli/type I cells...glucose...glycogen....liver

Those are the best I could come up with. Where there are /, you will really have to know by what you have been learning which one should go into the blank. They are both the right answer, but if you haven't talked about one, or you have a word bank and one of those isn't in it, your teacher will know you cheated.

please help i am so lost i need help with this chemistry study guide?

We Answered:

To find the molar mass (g/mol) use the periodic table.
I'll do NaCl.
- the atomic molar mass of Na is 22.99
- the atomic molar mass of Cl is 35.45
- add these together: 58.44 g/mol
So, this gives you (a) the substance formula weight
To find (b) I'd assume you'd use a formation equation to find the coefficients of the compound.
This is what I'm talking about...
Na + Cl --> NaCl
- this is a formation equation
- the charge of Na is +
- the charge of Cl is -
Therefore the coefficient of NaCl is 1.
Take your molar mass (g/mol) and multiply it by your 1 mole of NaCl
58.44g/mol multiplied by 1mol
this cancels out moles and your answer is 58.44g

I hopefully did this right?

Where can I find the answers to the Campbell, Reece Student Study Guide to Biology Eighth Edition?

We Answered:

Speak to your teacher. If he would like you to have the answers he will return them to you./
