Size:  120.9 KB how is answer D in the mcq.
Won't it be B cuz artial systole means contraction of atrium so many blood reached ventricle and graph shows ventricle volume in y axis

During atrial sysole, the atrium contracts yes. Therefore the pressure in the atria is higher than the ventricle, so blood will flow into the ventricle. So, during atrial systole the volume of the ventricle should be the highest and just about to go down as the heart will soon enter ventricular systole.
I may be wrong though

it is D because when the right atrium is at systole most of the blood is forced out of the right atrium to the right ventricle, and at D there is most volume of blood

No way,in o levels i finished every single one of them but now i have no chance,
The QP i finished is Bio Unit 3 cuz it was easy but now i think it was complete waste of time.

Thats the most controversial topic,will it come or not.
I think we read the teacher's guide for new biology and for unit 3 it says that teacher could skip Question number 2 as most of it not required now(except some e.g. implications).So we stopped doing it but our new IAS books has Reference in the Thinking Bigger Portion.I was so confused that i did every thing and swiped nothing

Download the Mapping Guide.It does not say much about Paper 3 but core practicals are the once you most for Unit 3.Did you read the Lab Book,it might be highly helpful.

Major things will microscope eyepiece calc.,Cell drawing from picture,Maths-heterozygous index,allel frequency.And graph graph graph
