2) E - Look it up in your books

Answer 2

What does this have to do with homeschooling?

Homeschooling means homeschooling not 'any problems with school stuff whilst at home' or even 'doing school stuff at home'.

If you're homeschooled either: ask your mum; open a biology book or two; or click on a biology website.

If you're not homeschooled, you're in the wrong place and, as already suggested, it'd be more accurate if you posted this in 'homework help'.

Although quite how you imagine you're ever going to learn anything by quoting answers from other people is beyond me; what do you plan on doing when your teacher asks you to explain the answers if you don't understand them!

Still if you are struggling with your homework you could always: ask your mum; go back and ask your teacher; open a biology book or two; or click on a biology website.

Alternatively you could try thinking: eg for question 1, where and how does gaseous exchange take place; and in question 2, which of the structures contains any cilia? And do you breathe or swallow cigarette smoke? If you breathe it, simple common sense says the answer isn't going to form part of your GI tract, is it? (hint, hint).

Answer 3

You should post this as a question in Homework help not Homeschooling.

And no-one should answer you.

Search the 'net for the right answers. You've already proven that you know how to find things here.

Laziness is the next best thing to failure.
