New info on the night before the exam. Spectacular.

The answer is option A i.e., adding artificial fertilisers.
Adding artificial fertilisers causes eutrophication. Digging plant material does not have anything to do with pollution.

According to the ratio, chances of being a taster equal chances of being a non-taster, right? So the chance that the child will be a non-taster is 1/2 or 1 in 2.
Does that make sense?

ahh, i got it thanks !!

but the syllabus says you should know that xylems funtion is to conduct.......i think there is a diff conduction term in biology

the same thing in xylem | it means that xylem is capable to conduct water and conduct in this sentence means that xylem allows water to pass through it !!
