**SAT II Biology December 2015 Discussion**

I believe grasslands was an option, but it was a specific type of grasslands. Had a name before it I think.
I didn’t even dare look at the M section. I finished the test, went back on those that I skipped, wept a bit, then closed my book and hoped for the best.

was the greatest biodiversity the coral reef?

@kjhnbgfvdcrftgyh That’s what I said…I was between that and temperate forest

@kjhnbgfvdcrftgyh Yep that’s what I put

It’s definitely the coral reef. Tropical rainforests and coral reefs have the largest biodiversity in our beautiful little planet.

Did the tapeworms evolve their roots from plants? It was between that and chemoautotrophs but I thought only Protists and bacteria are chemoautotrophs (also, the tapeworms were stealing nutrients from bones of dead whales, not producing them themselves)

Tube worm things, right? I believe the question refereed to how one could identify whether the sex of the worm was dependent on the location of its development. Females grew on the bones, males grew on the females. I’m not entirely sure though. I just remember the other alternatives being bizarre.

@AGoodFloridian that’s what I answered. Yeah it was tube worms, not tapeworms.
@sukhtheduke1 They definitely aren’t autotrophic, as all animals are heterotrophs. And I don’t think it’s possible for them to have evolved roots from plants, as they are animals.

Yeah @AGoodFloridian I put that as well.

@Lbelle43 all the other answers seemed wrong though…

Was this the one about the worms with red plumes? Wasn’t the answer taking the nutrients from bone marrow

@sukhtheduke1 I put the same answer as @avu017

What did you guys put for the one about the female tapeworm and why she has males in her body? @AGoodFloridian

Also, what did people put for the one about conjugation and why it’s interruption would be useful and where a single circular strand of DNA would be found? I put bacterium. Thanks!

@greysanatomy3113 I can’t recall word for word, but it was definitely to do with sperm depositing. I remembered the case of the anglerfish, who also live in the deep, aphotic zone. Females are much larger, and males attach to them, releasing sperm and eventually their whole bodies, leaving virtually nothing behind. Fun stuff.

@greysanatomy3113 Was this from the core section? If so I also put bacterium.

@AGoodFloridian so did you put like that they can reproduce without mating?

@avu017 Also, what did people put for the one about conjugation and why it’s interruption would be useful and where a single circular strand of DNA would be found? I put bacterium. Thanks

Yes @avu017 it was. Do u remember what you put for the conjugation one as well?

@greysanatomy3113 what were the choices

I don’t quite remember the one about conjugation… what was the question asking?
