Biology: Discussion, Questions & Potential Solutions

The questions weren't too hard, but my expression was probably poor lol

My friend was laughing (not literally) because he was randomly reading about that species (whatever it was) and knew its characteristics quite well.

In my exam there was a question about tortoises & I spent a lot of my childhood learning about them out of personal interest.

Usually that prior knowledge doesn't make too much difference,  but it's a good mood-booster

What you guys say about the question where there is excessive cell death

[AISHAB]

1. Wide, broad feet: allow better movement on sand and swimming ability, ( I assumed it was some kind of half whale half hippopotamus amphibian.)
2. I think i said something about a vestigial pelvis?

If you google ambulocetus you can see the actual animal, but i think that's irrelevant as long as the features you proposed and the explanations were reasonable.

Could we have also said flippers enables them to swim in water and catch prey
Legs similar to those of ancestral land mammals, enabling them to quickly run away from predators.

I said flippers enabled them to swim and catch prey/ swim away from predators

I think I did well, but I can't be too sure lol. It was a better exam than last year but it was still a bit tough. There were some really easy questions, though.

I did that, too.

I talked about cell mediated immunity for the botox question because I thought that it was in the muscle cells, which is how they were being inhibited...

I got stuck on the very last question and the article question about the social/biological implications of golden rice since the article didn't state any negatives about it... unless I failed to find them.

I did the same thing.

[gab.r_se]

I'm SO glad that's over. Good luck for the next exams you have, everyone!

For the bt cotton implications, I said
Social- less cost for farmers to buy insecticides
Biological- allergies for workers

And for the gmo
Social- less cost to buy Vit B supplements as it combats the vit deficiency
Biological- gmo moving from a controlled to natural environment where it can breed with wild rice and cause loss of variation

Damn, I think you're right. I guess both could be accepted as the initial injection may meet some humoral response, hence lessening the amount of toxin reaching the cells, although cell-mediated is certainly more correct.

What you guys say about the question where there is excessive cell death

I talked about cytotoxic T cells, as I thought they were leaning towards autoimmune diseases.

[AISHAB]

Does anyone remember what the said the hypothesis Elsa was testing was?

How did you guys find multichoice?
