But are there really enzymes in muscle tissue? That's what backed me away from putting enzymes denaturing.

"are there really enzymes in muscle tissue?"

That is what we learn! Enzymes are responsible for all metabolic reactions -- eg glycolytic enzymes, oxidative enzymes in mitochondria... both found in muscle cells responsible for creating ATP [energy to enable life to continue!] ... in fact CO2 is a by-product of aerobic respiration

Oh my god. I put greater than 1400Hz and i put up to 120,000 (that is for bats!) i confused bats with humans... god dammit

How about the ATP molecule question, what answer did everyone put?

MC or S/A. I cant remember.

How about the ATP molecule question, what answer did everyone put?

Wasn't it about having a common ancestor or soemthing?

omg i think i put C. was so confused though something about it being developed in the earliest organisms.. then retained it to pass on.. i thought it was linking to natural selection of favourable characteristics :/

hope i dont sound dumb LOL

Was unhappy with BOSTES this year. That test had no scientists whatsoever, like wtf? no morgan, watson, crick, franklin, wilkins, mendel, boveri, sutton, beadle, tatum. Also, apart from the first dna question and the evolution question there was like no Blueprint of life. Felt like i was doing maintaining a balance and search for better health the whole time. No mutations, no genes maintaining health, no punnet squares, no pedigrees, no meiosis, it had jack shit.

couldn't agree more ^

Hoping for a band 6 with a bad rank and bad school with approx 90 raw

Lol damn looking back i dun goofed on some MC, what did you guys do for 15? I put C

 

[luhanbby]

i put B because i thought the original parent plants for Mendel's experiment was TT x tt? :/

what did Q15 ask ?

I thought it was co-dominance since they bred 2 and got 3 phenotypes?

Also the sound shadow asked for frequency range so I don't think 1400Hz+ is right, since it doesn't imply a limit

So answer would have been 1400Hz - 20000Hz. Damn, I hope they take 1400Hz + as correct since the + implies to the limit of human hearing.

but as the frequencu get higher, the wavelength gets lower.

v = f*lambda

v is constant so as f increases, lambda (wavelength) decreases, hence produces a sonic shadow. Even if we cant hear that high frequencies the sonic shadow still happens

For question 15 there was three different colours produced in the offspring, so shouldn't D be the answer?

 

[ifireballx]

For question 15, if you related to mendel it would be RR and rr however since it is codominance it must be RR and YY where RY makes orange.
Also remember that mendels ratio in genotype is 1 TT : 2Tt : 1 tt and that he did two crosses. The first crosses was between two purebred and the second was crossing the resulting peas ie Tt x Tt to produce the 1:2:1 genotype. 3:1 mendelian ratio was the phenotype.

the answer is Co-dominance

bahaha yea obviously i wasnt thinking xD ok i think im like down to 17/20 far out

bumping my explanation
