Burns 2.. At least it's close... I think, never been there.

Same! It's right next to Central Lib on Albany St, from what I can see on the map. So not that close but at least it'll be easy to find haha

lol yep! i think its the one that you can see when you stand in front of castle 2, and look diagonally to the right. I think. lol

Commerce 2.22 .... where is that? :s Lucky people who have st davids!

I'd rather have commerce 2.2 than St. Davids!

Hey everyone, Cells Q, I'm not quite sure what we need to know for the last objective of Lecture 16...
'Explore the diversity of relationships between photosynthetic units and cells'
What does this even mean? Is it about the Apicoplasts and Cyanobacteria, or something else?
Thanks guys!

Thanks guys!

From the lecture slides, I would think that its just the Cyanobacteria and Vaucharia litorea/Elysia chlorotica, and that Apicoplasts demonstrate how different areas of cell biology cross-inform each other (last objective point?)


Oh, and a belated welcome to MSO!

Erm... I'm going to hazard a guess that the question may have been talking about endosymbiont theory, and how the chloroplasts were thought to have been photosynthesising prokaryotes which were assimilated into a pro-eukaryotic cell, the relationship proving mutually beneficial (prokaryote got a safe place to live, pro-eukaryote got a free energy source), eventually forming what we now call a 'eukaryotic plant cell'... And then how there's the different types of these inside plant cells (like the chromoplasts, chloroplasts, other assorted plasts)?
Although I've never even heard of 'Vaucharia litorea/Elysia chlorotica', so it's possible they've added something to CELS this year and I'm way off track.

This was actually an example from last year as well, just to recap Elysi Chlorotica is a sea slug, and it eats algae (which here is Vaucharia litorea). It digests all of the algae EXCEPT for its chloroplasts, then uses the chloroplasts in its own cells. I'm not sure if I'd call it "mutually beneficial" in this case, as the poor algae is still killed.

I thought it was pretty cool of the slug (I hate most slugs), so that's why I remember it I guess.

Very cool, had completely forgotten about it, lol. Definitely not a mutually beneficial arrangement as the slug is pretty much taking the poor algae's lunch money :'(

Hey, for Lecture 5 for Cells, does anyone know where Vancomycin acts on the bacteria? The diagram in the slide isn't so clear...

Thanks in advance.

 

[Voldemort]

With penicillin and vancomycin, one inhibits Transglycoselation while the other inhibits Transpeptidation. Can you see using that where Vancomycin acts?

vauch aaaadfkdafdjfeioafjdsfhdsafjd. and elysia chlordoafjdifjasdkfjsa. WTF is all i can say.

i know that penicillin inhibits transpeptidation... so vancomycin must act on TRANSGLYCOSELATION! thanks to whoever asked the question, would have completely ignored this part if you hadn't!

When applying the process of science, which of these is tested?
a) A question
b) A result
c) A prediction
d) An hypothesis

The anwer: C, prediction.


Why not hypothesis?? What's the difference??? 0_0

 

[SeeKay]

[OFFTOPIC]I think it's spelt transglycosylation (in case spelling matters in the exams (which I think it does) )[/OFFTOPIC]

And yeah, I had the same question myself - wouldn't hypothesis be the better term to use in science :S

 

[Sam]

[OFFTOPIC]Most dull lecturer ever - RE: CELS today.. Guy just stood there and stared at his computer screen. At least the old physics lady is brilliant haha[/OFFTOPIC]

I had the same thought with that question. Seeing as all we've been taught is that the hypothesis is the be all and end all of the scientific method it seems strange to throw question like that from left field. I guess at least it won't appear on the terms test now xD.

Guys, GLM marks are out

 

[Sam]

Guys, GLM marks are out

Goodluck everyone!

 

[SeeKay]

How did everyone do? Missed out 5% by .12%...

 

[Sustel]

How did everyone do? Missed out 5% by .12%...

uh missed out?

My reaction would be: just got 95+% for the CELS GLM!! XD
Which by the way was my reaction

Turns out its actually 97.6% of the GLM
Although that is not to say that I wouldn't be interested in knowing what I got wrong

 

[hermafish]

Got the same as you guys

 

[alice]

I also got the same.. interesting.. would like to see what the wrong one was!
