Nebbermind:
my dd told me 1 student in her class ask a question like this too.. (was it your idea, nebbermind)For magnetic qn, i remember having to decide if a telephone has magnet. Think the old styled phone had magnet in their ringer/bell n also the spkr n mic.
But I think modern phone is electronic n even the spkr n mic is piezo type system.
So how do we know what kind of phone they talking abt?
he ask the teacher is it true that some phones have no magnets and some cooking pots are fully made of metal and yet the handles will not feel too hot while cooking. the teacher said, \"in pri sci, we learn the basic fundamentals of the natural materials. however, science is always advancing itself and we have to keep up with the technology, except that when these new technology goes into the syllabus, it confuses the children....\" i rmb this very well as i find it very well said... -

Roots only absorb mineral salt and water from the soil. hence A is out. C and D cannot happen as the food carrying tubes was removed. -
