    The ratio of green to white is 3:1. This means that the parents were heterozygous because two traits have appeared in the offspring. Now the ratio of green to white is 3 to 1 so that means that they are not co-dominant and one is dominant and other is recessive. As the green is more so green is...

    In parts (i) and (ii) you have already calculated the number of moles of the reagents the student used. From the equation you can see that 1 mole of barium nitrate reacts with one mole of sodium sulfate to form 1 mole of barium sulfate and two moles of NaNO3. This means that the reagents the...

    according to the ms, ur answer shouldn't be wrong because ur %ages are evenly spaced, n u must have written correct volumes respectively. but it is a suggestion not to leave such a huge *gap* there. like u used 0 and then directly 40 and then so on with a difference of 20. the third mark is for...

    O/N 03 q. 6) the answer is A. the length given beside the cell's drawing, written 35µm, when measured with a ruler gives approximately 10.4 cm. measuring the length of any of the mitochondria, we get about 1.5 Use unitary method, 1.5 : x 10.2 : 35 x= 5.14 which lies in the...

    the question says *the fact that the palisade mesophyll is twice as thick as the spongy mesophyll* therefore C, cuz in A spongy mesophyll layer( lower one) is twice the palisade-upper one.

    As far as i understood this, lung volume has no impact. Maybe once we have the right answer we *could* make a connection. I did the same u did, multiply breathing rate with tidal vol ( the vol. of air breathed in and out in one breath). Doing so we get the amount of "air" entering lungs...

    Sorry for interrupting here, but there ws a slight mistake you made there. That answers u get by multiplying breathing rate n tidal volume are the volumes of air breathed in and out in 1 minute not oxygen absorbed. Because its stated that the efficiency here was same, the concept didnt really...
