But why did they refer to the volume of air absorbed as the volume of air exchanged , because the more air was exchanged in each breath , the more would be absorbed right? oh ok I think I got it. Thank you so much for the help17) The cell does not grow by mitosis. It only divides by mitosis. It grows during interphase (when it's not dividing)
26) I really have no idea if cambium cells are included. In my school, we take AP courses, and it's included there. Not sure about the AS syllabus though.
35) Okay, if I breathe in and out 5 times, and in every breath I take in 2 litres of air (exaggerated example). The total volume of air exchanged was 10 litres (every breath = 2 litres. So 5 breaths = 5 x 2 = 10 litres).
EDIT: a full breath is breating in and out once.
37) When an antibody fragments (breaks down), it breaks down into three parts. Remember that it looks like a "Y"
It breaks down into two "fragments antigen-binding" (Fab) and one "fragment crystallizable" (Fc)
The top part of the "Y" breaks down into "\" and "/" (2 fragments, each one can bind to an antigen)
The bottom part of the "Y" breaks down into "|" (the constant region/straight line)
Hope that helped
