um, i thought bacteria not fungi is used to make cheese and yoghurt?

otherwise, good quiz.

Kirtey

and why don't veins dilate, again?!

Fiona

Good quiz but it's bacteria that are used to make cheese and yoghurt.

and Kirtey, veins don't dilate because its arteries that are carrying the oxygen to the body. Veins are only carrying de oxygenated blood back to the heart, so they dont need to adapt when exercise is under way... hope that makes sense!
