I'm posting the PDF file that I need help with. When I go to PAL 2.0, it doesn't really help me at all and I can find anything in the book either. I'm at a complete loss and need help!!!  PLEASE.

If there is a specific question you need help answering, please post it word for word inside your post, not as an attachment.

I need help with the whole worksheet.  I'm slowly finding the answers to both of them, but it's hard.  There are also pictures on this one too.

The only ones that I can't figure out are the questions with the pictures.  I figured the rest of the questions out.  Unfortunately, the pictures won't transfer from the pdf

Motility


False.

If you want the whole thing, you're probably best to make a note request. This board is specifically for homework questions.

I'm not needing the while thing. Just help to figure out the answers to the picture questions. Even a website that will help us good enough for me. I don't have to have someone answer them for me. Just need pointed in the right direction to find the answers. I have the worksheets answered except the picture labeling. Anyway you could point me in the right direction for a website for them?

Cool, what is the picture question? Could you take a capture of the picture and the question associated with it?

I finally found them. Thank you

You're welcome!

Mind posting it? :D

It won't let me post it in question format so I will add the PDF.  When I get time, I will copy and paste into a word document and will type all of the answers in it.  I will do that for several of them that I've had difficulty with.

That is good, thank you for taking the time to do that.
