Biology ATP Paper 62/ Uncurled length.

[Haris Sal11]

After 24 hours of the exam, I'd like to confirm from the people who've given the Bio Paper 62 today whether the uncurled diagram's measurement was to be taken of the complete diagram or not. Here at our center, there's quite some variation in the answers ranging from 38mm to 76mm. Thanks

the first parts answer was 65 and the seconds answer was 74.

It was to be to taken of the compelete diagram....this is becoz according to the Topology of the diagram the uncurled length would be from the top of the plumule to the bottom of the radaicle.

The uncurled length is the straight length. So I think we had to measure the length along the seedling, including the curled part, assuming that it were straight. That's what I did, and I got 84 mm and 78 mm :S

If i wrote the length in Cm . Would I gain marks?

They won't deduct your marks as long as you stated the unit in your answer

Yes.. I did State Cm in my answer

 

[Snowysangel]

Yes.. I did State Cm in my answer

But listen, how did u measure the lengths?

Wouldn't that be the height then?

 

[Nouman1997]

75mm and 66mm if i remember correctly

 

[Snowysangel]

According to an experiment, this is what the uncurled length is supposed to be :S

I wrote 9cm because they told us to measure the whole seedling so I included the pea Cotyledon and the long root..

As for bean.. It was 7.6 cm .. I measure it from the Seed till the bottom of the root

I was so scared that I had done that wrong. I even took the straight length of the pea, it was in 60's and one in 70's. I was planning to cut that answer and measure just the seed instead, thankfully the time was up and I was saved

And in the diagram that we had to make, we didnt have to shade any where did we? Half of the people I know said there was shading required some where but I didn't shade. Want to know whether we had to or not

 

[thementor]

No as i said the question applied a simple rule of mathematics.....

If i wrote the length in Cm . Would I gain marks?

yes that wouldnt be wrong

Absolutely not.....In biology, candidates are not required to shade any part since the papers are checked on a computer screen and shading means that your diagram will not appear clear on the screen....you did it right....

 

[Snowysangel]

No as i said the question applied a simple rule of mathematics.....

yes that wouldnt be wrong

What rule of mathematics? uncurl means to make something straight...so the uncurled length would be measured on the assumption that the length was straight, so you measure the curled parts of the radicle with a ruler but by bit, and add up the total length...no? :/

 

[flaminheroes]

this was some serious voodoo crap :/

 

[flaminheroes]

biology is the subject of witchcraft :/ im suprised why we havent conjured up a demon yet.

 

[starship]

What were the answers to the testa part? where you had to compare...
