Divide $151 (in whole $ increments) into a number of bags so that I can ask for any amount between $1 and $151, and you can give me the proper amount by giving me a certain number of these bags without opening them. What is the minimum number of bags you will require?

Ice... how did they make it in the 19th Century.... Maybe I am just being thick, but they didn't have freezers or compressors (I think) and whilst we take frozen food / ice for granted, I was wondering how they actually created ice in the first place, or did they ?

I've been wondering about butterflies lately. Evolutionarily speaking, I understand that mutations cause different forms which may be more suitable for adaption. Some variations are more successful than others and those genes that caused the advantage can be passed on to the next generation. This is how different finches have differently shaped beaks and giraffes are somehow related to horses.
But with butterflies, I don't know how such a rapid change in form could evolutionarily arise. A baby chimp, fish, hippo, etc. looks like a miniature version of an adult of the species. But butterflies and moths go through a chysalis stage at the middle of their lifecycle which involves a specially specific constructed enviroment to develop into a completely different form (unlike tadpoles). How could genes for not one but two forms (catapillar and winged butterfly) be passed on? How does evolution explain this?
I give a very warm and kind thanks to the entomologist, lepidopterist or evolutionary biologist who answers this.
