Your teacher will for a fact i know that so dont use it twice
1. adverb clause, it shows that he realized ( verb ) that she wouldn't show up
2. it may be independent clause ( because it makes a complete sentence )
3. adjective clause, explaining who is holding the basket ( basket is a noun )<span />
I don't see a word in bold type.
The last one, plant and animals food sources both contain iron, but the iron in animal foods is more accessible to the body :)
