Biology Paper 1

[Haris Sal11]

Cuticle is a non-cellular layer preventing water loss...that was the answer
Insulin-both VARIED not constant
3.Muscles and diffusion
4.According to people it is Oestrogen...I do not knw...I choose FSH
5.B was the producer bcoz all carbon dioxide was going towards it
6.Virus not bacteria

It was a non cellular organism. Can't be Virus, you got it wrong bro. It was clearly mentioned that it was a cellular organism.

 

[Haris Sal11]

Viruses do have a DNA so the answer was virus in first column and not bacteria in second column (option D). Since it was clearly stated 'cells' and bacteria are unicellular so it can't be bacteria.

Virus is non cellular. The organism can't be Virus. Peace.

 

[Haris Sal11]

The organism can't be Virus since it doesn't contain cells. It's NON CELLULAR. No point in discussing this.

The answer to the exchanging things was Uterus wall, I went with Umbilical cord too. Shit.
Respiration/Photosynthesis answer was A.
Enzyme question number 4. Answer was A.

 

[altox876]

OMG I WENT FOR A!

Actually, it was C, Oestrogen I think.

 

[Snowysangel]

But the oxygen

It was A. At x both were occuring and at y only respiration was occuring coz respiration occurs all the time

but the oxygen concentration wasn't decreasing at y so respiration couldn't be taking pkace

 

[Snowysangel]

A said that photosynthesis wasn't taking place at y...would that explain why the graph started to rise at that point :/

 

[danial 234]

Fs

OMG I WENT FOR A!

Fsh and progesterone were clearly shown. The ambiguity is between oestrogen and LH

 

[danial 234]

No

What doesn't help malaria in vectors? warmth and CO2,right?

No. The ans was mosquito lay eggs in water

 

[altox876]

What doesn't help malaria in vectors? warmth and CO2,right?

Water eggs option. Warmth and CO2 attract them to humans.

 

[danial 234]

Can anyone tell me the correct ans of hormones one

 

[altox876]

A said that photosynthesis wasn't taking place at y...would that explain why the graph started to rise at that point :/

The graph is over a large time period(24 hours) so at that moment when O2 concentration just reached lowest levels photosynthesis was not occurring.

It was a non cellular organism. Can't be Virus, you got it wrong bro. It was clearly mentioned that it was a cellular organism.

yeah...exactly the organism can be bacteria not virus....

 

[thementor]

Can anyone tell me the correct ans of hormones one

well according to google it's oestrogen

 

[thementor]

The organism can't be Virus since it doesn't contain cells. It's NON CELLULAR. No point in discussing this.

The answer to the exchanging things was Uterus wall, I went with Umbilical cord too. Shit.
Respiration/Photosynthesis answer was A.
Enzyme question number 4. Answer was A.

yes i got uterus wall correct........

 

[thementor]

OMG I WENT FOR A!

yeah me...2 but now I think it is wrong.

 

[thementor]

It happens all the time

correct again

 

[danial 234]

If the graph that went to peak was LH then why would LH rise from 8th day

 

[altox876]

If the graph that went to peak was LH then why would LH rise from 8th day

This graph shows that answer was oestrogen.

 

[altox876]

Would someone clarify what the answer to the new organism question was? I wrote Bacteria and Virus but some of my friends said that the question said the organism was made up of cells, meaning it could not be a bacterium.

 

[danial 234]

Altox it shows thatLH rose at 12 or 13. While in ques it rose at 8th . My argument is still the same
