The kind of data that can be analyzed using a histogram might be ones representing a things such as a certain time period, or things like data using certain age groups (i.e one bar representing the first year of a business, one bar representing a certain age group such as 10-12 year olds, etc. ).
Butterflies undergo complete metamorphosis, and their life cycle contains 4 stages.
First, they are born as an egg.
Then, they are hatched as a larva. They now eat flowers and leaves and will molt constantly.
Next, they become a chrysalis, or a pupa. This is a resting stage.
Then is the long awaited adult stage, where butterflies take the form of the beloved, beautiful, winged insects we've come to admire. They no long grow and will now reproduce and repeat the cycle.
Hope this helps! Have a great day :)

Never learned it. Sorry! I wish I could help.
I'm pretty sure that would be selective breeding
