Answer:
zygomcota
Explanation:
discovered in Winter 1881
<span>Alveoli are specifically designed to quickly facilitate the exchange of gas from the lungs to the blood. They are very small, but with a very high surface area allowing a greater amount of gases to be exchanged in a comparatively short period of time.</span>
So, I decided to take another whack at this, specifically number 3, and at first I didn't really try to answer 'cause I have no clue what the word dueterostome means, but I do know that, for the other two criteria, A, arthropods is the only one that fits both.
also, on 6, it is b, because I remembered what an anther is and it has nothing to do with the eggs (it's the testes, pretty much)
and if I had to guess at 8, I would say it is d because all the others are characteristics of sexual reproduction. (I'm not sure of this, though, because I'm not sure where this defines the line for mitosis, both go through it, but at different points in the process, so I assume it isn't that one.)
Oh, we actually did a similar project in my biology class!
I looked at your punnet squares and they all looked right to me, so I will just explain how to find the genotype and phenotype.
Ok, so let me explain that for genotype they mean the letters, so for example if the penguin has a dominant trait, the genotype could be Ff, or recessive could be ff. By phenotype they mean the trait expressed, so if the penguin is dominant for freckles, the phenotype would be has freckles.
Now I don't know what your teacher wants you to do, but in my class we just flipped a coin to decide whether we would use the dominant or recessive trait.
Hopefully that clears it up a little bit for you :)
