Biology ATP Paper 62/ Uncurled length.

[flaminheroes]

I find paper 2 much easier since if we don't know an answer we can always use the common sense we have been granted but paper 1 is like, you have 4 choices and only one of them is right. andddd at times it feels as if 2 answers are right, and that is the main cause of all mischief! choosing one out of two.

oh yes lol. I forgot about paper 1 having two almost similar right answers. Common sense FTW !

He?

better not forget it again xp

GEEZ! SOMEBODY TELL ME HOW YOU FIND THE TABLE VALUES; omg this... question 1(e)(i)

simple divide the time by 40, you'll get the ans.

since speed=distance/time. this formula is being used here.

but the radicle and plumule were both curled???

exactly that is why the question said, uncurled length of seedling....

 

[Haris Sal11]

Short plumule, long plumule. Thin radicle, thick radicle and the last one was small cotyledon, big cotyledon.

Cotyledon in the soil. Epigeal germination. Cotyledon out of the soil. Hypogeal. I wrote this and the small and large point.

 

[Buland Iqbal]

then y did they use the word UNCURLED??

Basically the maximum length of bean seedling and pea seedling were asked. Another way to put it was to use the word "UNCURLED". Therefore vertical lines were to be drawn from the top to the bottom indicating their respective lengths

PHYSICS ATP QUERIES:
1.what was the appropriate instrument/method of measuring the distance in that kinematics(graph) question?
2.were we suppose to include a a rheostat in the circuit of first part of that solar cell question. (it originally said how to get the voltage across it)

1. Tape Measure/Measuring Tape/Trundle Wheel
2.We were not supposed to add the rheostat. It was a one mark question so not much effort required. A voltmeter and a switch were required.

I personally feel that we should have measured the full uncurled length of the seedling. It makes no sense for the examiners to use the word 'uncurled' other than to indicate that the length to measured was one where the curls had been straightened out. The exact meaning of the word uncurl is:
-to become straightened out from a curled or coiled position
-to straighten the curls of : unroll (via merriam-webster)
Hence, I feel that we should have measured the curls as well.

Hey what was the answer to the first question in section B in p2 variant 22?
