I'm assuming an article is not a part of speech. Next, I'm going to go with v, as there are no contractions or abbreviations in bacteria. For 3, they are both organisms, and that is a noun, so A. For Part B, "The death of an animal means life for fungi because as fungi decompose the organic material from the animal, they also consume nutrients from it." Hope this helped.
I think so.. does this help?
Most likely to look at the cover, to view the name title, etc. or even to view the publisher or authors of the titles. You will also probably be brought in by the headlines and previews shown on the front cover.
