Q

Explain how humans meet every requirement of the PMC model.

A

Humans have program aka DNA which tells the body what to do and how we are made up. We have metabolism because we burn and use fuel/energy. Humans also have a container because of cells holding the DNA and our shell/skin keeping everything inside.
