(2) What is the function of a mango seed?

(3) What is the function of the meat of the mango?

(1) To allow the organism to grow because the skin does not grow.

(2) To enable the mango to reproduce so that it will not become extinct

(3) To attract animals to eat the fruit so that the animal will help to disperse the seed.

just offering my help.

(1) Why do organisms moult?
insects moult in order to grow bigger as they are covered with exoskeleton, therefore when they grow, their skin does not stretch together so they need to shed its skin in order to grow bigger.

(2) What is the function of a mango seed?
the mango seed helps the mango plant to reproduce so that its own kind will continue to live and not extinct.

(3) What is the function of the meat of the mango?
the meat of the mango is sweet scent and it attracts animals to eat them so that their seeds can be dispersed away from the parent plant for better survival.

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?
