Hi guy!

Do we have to know about lung diseases etc or just know how to interpret information on graphs?

And also, could someone explain the heavy isoptope experiments on DNA to show it is the semi-conservative model?

It's not on the spec, but they might give you a question with information on ORS and tell you to apply your scientific knowledge to answer something like "suggest the use of sodium ions in oral rehydration therapy"

I might say to replace those lost from the epithelium though it depends on the information they give.

Are we meant to know about the nodes and electrical impulses in the heart?

It used to be in the spec but I don't think it is anymore

OCR AS BIOLOGY A (2015) - These puns are getting cornea and cornea...

This is a quiz for Biology and it is getting constantly updated so it's really great for quick fire revision and good for practice of Multiple choice questions. Although its based from the OCR Spec, it's still useful for revision because biology is simply biology... So enjoy revising!

Hi everyone,

When measuring the magnification of an image and it gives you the actual image on the paper and you have to measure it yourself (They don't give you any figures) how do you measure the image? Obviously with a ruler, but do you measure it length ways? Width ways? Across the largest part? I'm just really confused Dx

Thanks for any help! :smile:

Resigned to the fact that I'm going to fail biology. I have English lit tomorrow morning and I only get a 2 hour break... Plus I keep making silly mistakes which are costing me like 3 grades per paper
