Could someone please tell me if my working out is correct
Attachment 811010
And for this, could I say something like: it is backed up by scientific theories and figures, and approved by other scientists?

It says the attachments can't be found. Perhaps you could write in text what they say?

This information is about Jack’s circulatory system:
The volume of blood pumped out by Jack’s heart in one beat is 40cm3.
Jack’s resting pulse rate is 80beats per minute.
When Jack is exercising, his pulse rate increases by 90%.
Calculate the volume of blood, in litres, pumped out by Jack’s heart in one minute when he is exercising. (4marks)

A paper in a scientific journal includes some detailed models of anaerobic and aerobic respiration in yeast. (I) the students have confidence in the information in the paper.
Explain why. (2marks)
