It says a diploid GAMETE, meaning it's already undergone meiosis so total number of chromosomes in triploid zygote would be 24.

I think it's B :/

The triploid question got me as well, but I think its D) 15... since the cells are gametes, and they're just going to fuse (meaning they're supposed to have 8 + 16 = 24 chromosomes in the end product, but the resulting gamete's average number is 9, therefore 24 - 9 = 15...

Btw guys, is anybody's blackboard not loading? The page won't even load, and it's been around an hour... I suppose the server's down or something!

Yea Uni network died today, apparently some something happened in the data centre and the fire brigade had to come in.

[OFFTOPIC]OMG! I actually saw the fire brigade go! We were picking up my brother from his school, when it went going past (it was actually trafficky but yes)
Any idea what happened?[/OFFTOPIC]

A friend of mine who works in the IT department said it was an electrical issue, ended up having to evacuate the building.

NB: hubs discussion board will close 1700 Thursday.

WTF? what building was evacuated?

No internet at the library for like two hours this afternoon, probably still isn't any haha. Science library was so empty, everyone was just leaving.

[OFFTOPIC]people were leaving, because there was no internet? what do these people bring nothing else to study? LOL. [/OFFTOPIC]

Fire in the server room that knocked out half of the network... IT face-palm.

My flatmate works for them, I've been hearing all night about how many angry students plan on applying for special consideration because they've left study till the very last minute, then the network died when they needed it

what because all their notes are on the internet are they? what sort of lame ass excuse LOL!

EDIT: oh wait, i just realised that some people's exams start tomorrow! WOOPS. haha

Are all the slides for the Thermodynamics PCC lecture with the band on the side examinable? I can't remember!! Panic! I feel like some of the ones with the bands were and some weren't, but we need colour slides to figure it out

Second that? And do we even need to know that lecture, they already examined it in the mid semester so I'm not sure??

 

[Bluerock]

I think it's Chem that doesn't test for the first two modules guest lecturers. In Physics I think the only green slide one you needed to know (or at least the lecturer put a lot of emphasis on..) was that green striped slide that was tested in the mid term, about the different heat losses for different age groups. Feel free to correct me if I'm wrong but it's what I'm going with.

 

[Sam]

I very doubt that they will waste any of the 55 MCQs on examining the old hot topics, would be a true waste of time. I've never seen any on the previous exams, I'm going over them all again tomorrow so I'll let you know if I find any. I wouldn't bother to relearn them tbh.

 

[somerandomguy]

On the PHSI blackboard page about the final exam it says "includes questions drawn from all 6 modules, Mechanics, Bulk Materials, Thermodynamics, Electricity, Optics, and Radiation and Health".

And I'm sure the stuff from all the PCC-lecturers is examinable in the final exam. Q27 in the 2011 exam looks like the Thermo guy ("thermoregulation").

I remember him putting a lot of emphasis on that slide, but I have a hunch that there were other green sided slides(!) Like what kind of person is more likely to reach their critical temperature first.

It's a shame that the slides on blackboard are in black and white........!

Yeah there were definitely other green slides. Annoying how he only told us they were the important ones halfway through the lecture haha.

Here's a question causing some debate on Peerwise...

A triploid plant is formed through fertilisation of a diploid gamete (2n=16) with a haploid gamete (n=8). If the average number of chromosomes in the gametes of this triploid is 9, how many chromosomes are lost on average during the full course of a single meiotic division.

Options
A - 3
B - 6
C - 7
D - 15

I feel that the answer is B - but if someone could confirm this, that would be great​

Wierd question... haven't seen anything like it...
My guesstimate would be A. The parent cell of meiosis has 24 cells (16+8), so half the number of chromosomes is 12, so in one division 3 are lost...
But then again, how do triploids undergo meiosis? They have 3 copies of each chromosome, so 3 homologues for each one. If we assume 2 sets are pulled one way and one the other, we end up with 2 cells with 16 and 1 with 8, so 2 cells lose 7, 2 lose 1, making an average of... 3! I'm pretty sure its A... what's the answer on peerwise???

Hey guys, for the medial lemniscal pathway for sensory information, do the primary sensory neurons travel up the spinal cord through the dorsal horn or the dorsal column? I have it down as dorsal horn but I recall that dorsal horn is where the cell bodies should be? :/

 

[Wongtong]

I think that primary sensory neurons travel up the dorsal horn. The dorsal horn contains both unmyelinated axons and cell bodies.
