in Bio the ques ask us to draw the graph bt which graph we have to draw???
I mean we hv to draw curve,straight line or any other...plz help...

if it askes for a graph, then draw a curve... if histogram, then equal width and continuous chart...
if line graph , then also a graph has to be made... straight lines graphs r rarely drawn...!

@Adnanj,
Ans to 1d. First, cross the Resistant Plants with Non-resistant plants. Sow their seeds and wait for them to grow. While growing, wrap them with kite paper to avoid any contamination. Now spray the weed-killer to the new and sexy plants which were planted if they showed resistance, the resistance is dominant, if not resistance is recessive. Got it ?

what is a kite paper??? :sorry:

@Adnanj,
Ans to 3. 1st reason: The variety of plants are different. So their genetic makeup is different so they function differently.
2nd reason: Their time of maturity maybe different.

If you join your plots with ruled connections (point to point) it is acceptable in Biology ATP. In Physics ATP, one must draw a line/curve of best fit.

Its nothing Ignore it. Did you get what I was trying to say ?

In most of the ques he has asked to draw a graph.....In some ques he has said that plot the results on the grid below....than what to do??? :Search:

can we say that they were kept in different light intensities???

 

[KarachiRocker]

Oh yeah sure

So we can join the points with straight line???

 

[abcde]

Yes you can join them with straight lines. Remember this acceptable for Biology ATP only.

 

[adnanj]

but isn't it advisable to use curves???? it gives greater accuracy for the follow-up questions..

no i didn't

the curve is the best option unless asked to connect using straight lines.

 

[Muhammad Talha]

ok last time straight lines ya curve???

 

[adnanj]

ok last time straight lines ya curve???

i'll go with the curves.

 

[KarachiRocker]

Ok. sir here is the thing.
If we cross two pure breeds which have contrast traits, the kids are going to have that trait which is dominant from their parents.
So.. to see whether the resistance is dominant or recessive, we to cross pure breeds and sow their seeds ( at least 4) and let the seeds grow.
Once the seeds are the size to their parents, we have to spray the weed-killer on them to check whether the kids are resistant to weed killer or not. If they are resistant, the RESISTANCE is DOMINANT, if they are not, the RESISTANCE is RECESSIVE.

 

[abcde]

I am absolutely sure that in Biology ATP, you are not expected to draw lines or curves of best fit unless the question asks you to. So you can draw straight lines. If you check any mark scheme, they say straight lines are accepted.

@adnanji n abcde:i m so cnfused..... :%)
