How was Biology paper 11 and 31 ?

[Mr.Physics]

Aoa !
How was your paper ?? I found paper 31 a bit hard !!

 

[twistedsoul]

Tbh, they were easier than I expected they'd be. Paper 1 was easy but there were 2 questions that were a bit tricky, the one about the flies and the one about dry mass. What were your answers?

I did A. As it was said that orange flies always produce orange so they had both dominant alleles ie OO and they were homozygous . For red flies crossed with oeange it was written that some offsprings are red and some are orange so it meant that red flies were heterozygous ie Rr.
So Rr×rr produces 1:1
Most of the dry mass from balanced diet is from carbohydrates,proteins and fats !!
What was ur answer for that amylase question where ph decreased from 13 to 1 ??

i did red is dominant allele ... because red flies were also having orange offspring and only dominat allele can be expressed in the phenotype and be heterozygous in genotype
i did speed up then slow down

Speeds up then slows down.

True, but only if we know that the orange fly has the recessive allele for sure. The allele for the orange fly could be dominant or recessive (in this case, the red fly has the dominant allele) and the ratio would still be 1:1.

well 3 to 4 questions were hard

 

[lina1999]

What was the answer for the percentage?

 

[twistedsoul]

What was the answer for the percentage?

My answer was 1.42%

 

[lina1999]

SERIOUSLY??

 

[twistedsoul]

SERIOUSLY??

Yeah, what'd you get?

 

[twistedsoul]

well 3 to 4 questions were hard

Which ones?

 

[killa125]

could anyone answer my questions on the thread i just posted. I really wanna know if i got my answers right

 

[nigel_h]

there was a question in p1 asking which one of the 3 was reusable or something like that..what was the answer? energy?

 

[killa125]

It was carbon and water cycle

Carbon and water are recycled, energy is lost.

 

[killa125]

Which ones?

Why were there 50 wolves? It was in V31 and i really want to know the answer

 

[Muaaz Iqbal]

Which ones?

The end one Photosynthesis one
and That Harmone one Thats it
