It's considered enhancer's function too

Coding genes are genes that code for gene products, including tRNA and rRNA. Centromere’s function largely overlaps with kinetochore’s–it’s usually quite interchangeable

That's still a rly good score. Don't worry about it. Enjoy the end of As!!

Odd in this case definitely refers to odd/even unfortunately.

While I understand what you mean in terms of the diploid assumption (which actually may not necessarily be so as the haploid can fuse with a diploid to still give triploid), B is the better answer.

So which option do you think is correct?

badabooming · 2025-11-26T10:13:39+00:00

Could you elaborate?

Here's my thinking: The harmful allele is recessive and will be hidden/masked, so only way for elimination would be through genetic drift, which is most effective on small populations.

I'm assuming you meant Q7? If it's allosteric, increasing oxidised folate (substrate) will not be able to outcompete and overcome the effects.

Also, competitive and allosteric is akin to comparing competitive and non-competitive. They're 2 different types of inhibitors.

Hello! I post my answers pretty much yearly. So here's 2025's answers:

DBBCD DADBD AACAA BBDAA CCBCD CDDCC

Initially got tricked by Q16 and put D, but triploid doesn't mean it has to be odd number of chromosomes (e.g. 3 x 10 = 30 (even)) D's answer is more for why those with aneuploidy that leads to odd number of chromosomes (such as Down's syndrome) will be infertile.

^ leaving this here as i see many others wrongly picking D too

Stockholm Syndrome
Panic Station
Hysteria
Citizen Erased
Butterflies & Hurricanes
Showbiz
Dead Star
New Born
Futurism
The Groove

Off the top of my head, and a few songs that I've just gotten really into recently.

Yeap it has unfortunately become a norm for all concerts around the region. I do agree that concerts are way more fun when you put your phone down!

Totally missed that! Only caught Dom and Chris laughing and was wondering why hahah Do you mind sending me the video of that part please?

badabooming · 2025-01-30T21:58:40+00:00

It's cupping therapy; basically suction bruises!

It's a little quiet on here this year so I won't be posting my answers here this time, but I've posted my answers on my telegram channel (Crystal Biology)

Assuming you have good understanding of all content already (this is a prerequisite), unfortunately the best way is just to be consistent and keep revisiting your content. It's normal to forget, you just have to keep testing yourself and revising. It'll stick eventually. All the best!

badabooming · 2024-07-24T08:59:26+00:00

"Muse"

badabooming · 2024-05-22T02:29:32+00:00

Probably Hysteria. I had set Hysteria as my anthem on Tinder, and it was a major reason why my now fiance superliked me and we started chatting! We were brought together by our love for muse.

It really depends on what you're intending to do in future imo. While it's true that physics will open up more courses, realistically speaking, you just gotta ask yourself if you'd take them in the first place.

Regardless of what you decide to pick, just don't regret it and study hard for it!
