Thot 28 was excluding the egg stage!!!! I put 28! :shock:

Does anyone know???!!! :idea:

[/quote]its 24 cos they said after the egg stage, so we don count the number of days it spends as an egg, only the number of stages it spends as a larva and pupa, which is 18+6=24. Answer is 24.

mum-in-action:

It should be 10... Read carefully, the graph said that how long did each stage lasted or smth like dat. I am veri confident that it is 10, cus the pupa stage + larva stage for it to reach adult stage. Hence, it is 4+6

nono. the stages on the graph are put wrongly. it goes like this. egg, adult, larva, pupa. the pupa has 6 stages. egg has 4 stages like the adult. larva has 18 stages. so 18+6=24[/quote]

ya, it is 24.

Can someone check if the decomposition question, can the bin be placed in the dark to speed up decomposition?
