Biology Paper 1

[redd]

so how did it go? Alhamdulillah, mine went good.

 

[Taha Haqqani]

was easy as compared to ppr 2...hope this will improve the overall..

 

[danial 234]

was very easy except for ques 36

yeah.......

was very easy except for ques 36

oh u mean the hormones one....yeah....overall....much much easier than P2

 

[Neon light]

my bio p1 was really good. hoping for an A in average..

 

[Neon light]

was very easy except for ques 36

what was your answer to the hormone question....... i gave C as the answer

 

[Talha Irfan]

what was your answer to the hormone question....... i gave C as the answer

yeah it was C confirmed

 

[Farhan Saeed]

yeah it was C confirmed

What is C? Oestrogen

 

[Talha Irfan]

What is C? Oestrogen

Yes

 

[ritx]

n

Yes

No, it was B, LH. *confirmed*

What was NOT an effect of global warming? Was it animals migrating to cooler places? Does anyone remember option A? please share!

 

[ritx]

what was the answer to the 3rd question. Chloride and nitrate ions?
The lung pressure and volume graph? was it D?

What was NOT an effect of global warming? Was it animals migrating to cooler places? Does anyone remember option A? please share!

The answer was A, i.e reduction in sea level. Global warming causes rise in sea level so it was not an effect of global warming.

 

[Buland Iqbal]

what was the answer to the 3rd question. Chloride and nitrate ions?
The lung pressure and volume graph? was it D?

Chloride ions taken by diffusion and nitrate ions taken by active transport as indicated by the graph.

According to me, it was A, i.e volume was increasing (breathing in) and the rib cage would rise accordingly.

Hey can u people please wait till morning its not 24 hours yet

chill bro, it was the last exam.

 

[ritx]

According to me, it was A, i.e volume was increasing (breathing in) and the rib cage would rise accordingly.

that's the FIRST impression the graph gave, i noticed the PRESSURE graph started decreasing at D, and by A it had partially decreased, while inspiration the diaphragm contracts and WE HAD TO POINT OUT WHEN IT FISRT started contracting!

sis, LH was given see ur quoted url and try remembering the graph, on 14th day, the graph which went to max was LH and the small hump was FSH which was exactly below as it is , only Oestrogen was not shown. The pressure one was A before volume begins to rise

 

[Snowysangel]

Nope. The pressure only decreases BECAUSE the volume oncreases. The latter happens first

 

[Snowysangel]

Okay so excretion of carbon dioxide was diffusion and muscular contraction only na? Insulin in the blood remains constant and its secretion varies. What else was there?
