hanksAcha tw here's the thing ..
First of all as they've given 0.1 mm which is equal to 100 um
If u count the number of units in between the eye piece graticule.. They are 40 units in total
So that means 40 units = 100 um
Now measure the length as in the units using the micrometer scale given.. That is almost 4 units
Now cross multiply
40 units = 100 um
4 units = x
Answer is 10
that three fragements will be 2 of light chain and one heavy chain .... so due to light chain bind with antigen there are two light chains here... so the answers will be C simple.
lol which onw the latest one is the 3rd onelatest edition
18 - Ah I remember this one... cheeky one. Question says FOUR KINDS OF Amino Acids, thus maybe the same tRNA can bring them back and forth? Four different AAs need only four types of tRNA, and maybe a few tRNA molecules make more than one trips...
Answer - 4
16 - Google tells me that pairing up happens only in meiosis, and mitosis does not involve reduction of chromosome number
Answer - A (not sure can u check marking scheme and let me know???)
7 - measurement question. I can't do now but I can tell you that the minimum distance is where the rbc touches the capillary wall to the alveolar wall. And then u divide by 5000 to get the answer.
4 - when the cell and the solution have the same water potential, there is no movement of water. Thus the length of the cell does not increase or decrease. Thus the initial/final length value should be 1
Use the graph, and read off the corresponding concentration value...
Answer - C (0.45 moldm-3)
lol which onw the latest one is the 3rd one
yes exactlyIs this correct?View attachment 41595
lol...Samajh aa Gayi? Ya awein
It is there on page 108 and 109 in a background orange colorThat of butterfly wala.
Yaar wo Jo choti choti lines hain na..lol...
well sach bolu to muje 4 units wala samjao na please.
page 108 there is experiment for the semi conservative replication of DNa.It is there on page 108 and 109 in a background orange color
yeah there is.. ThankoooIt is there on page 108 and 109 in a background orange color
please image se samajao na..Yaar wo Jo choti choti lines hain na..
That count for one unit..tw chloroplast ki length is like 4 units...4 choti choti lines...
Aai samajh?
dunno how to use it.. Aap Aisa karo oct/nov 2011 par jao paper 11 question 5please image se samajao na..
agar drwing ki help leni he to ye lo link --> twiddla.com
phir screen shot le lena aur share kar do here... i really suck at magnidication.
thik hai.Du
