AS BIOLOGY P-33

[h4rriet]

Thank you so much.
But what are these values written in the marking scheme? i dont really get those.From where did they get 28/29.

And when finding the value on the stage micrometer,why did you take it as 10 units,not 3mm?

Because 20 is at 0 and 30 at 9. Therefore 30-20=10 corresponds to 9.

And I myself don't understand the table in the mark scheme, heh. I only checked the final answer and it matched the one I got, so I guess the method I used is correct.

i am not worried about bio P33 .........i am worried about Bio P4 .... ....i have consecutive clash papers after 20th may ....no time for good prep ... ....Oh GOD help me in this tough time ....!!!

alright, so i saw that my teacher was preparing bunsen burners and microscopes, so that means, food test and a microscope specimen, i hope that enzyme stool doesnt come :/

THANK YOU SO MUCH! I'm gratefull.
But one last thingg. Do we always take the values on the stage micrometer as 10,20,30,etc?

ya gt sum! be familiar wit stem n root (both dicot n monocot) for da slide!!
food tst: reducing sugar, starch n protein!
bt hav an idea of evrythn else too!!

No problem.
If you look at the picture again, there are 10 divisions between 2 and 3. That means between the 3 and 2, there's 10 units (because you have to count all the lines).

can someone please upload bio practical notess :/

 

[Bluejeans#]

*confirmed stuff* An enzyme experiment is coming.

so which past papers shud we practice ?

 

[Malik777]

I heard enzymes are coming for /33 :S

Q2 part b onwards PLease helpp :O

Same question plz help

42 EPGU - 10 SMU
1 EPGU - x SMU
42x - 10
x - 10/42 = 0.238 SMU

1 SMU - 0.01 mm
0.238 SMU - x mm
x - 0.01 x 0.238 = 0.00238 mm

Therefore, step 1: 10 divided by 42 = 0.238 x 0.01 = 0.00238 mm.

Step 2: 0.00238 multiplied by 1000 = 2.38 micrometres.
