I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Organs Zone. It has scientists studying health and disease in various parts of our bodies. Who gets the prize? YOU decide!
Great question!!!
Octopus blood contains the copper-rich protein hemocyanin for transporting oxygen. Although less efficient under normal conditions than the iron-rich hemoglobin of vertebrates, in cold conditions with low oxygen pressure, hemocyanin oxygen transportation is more efficient than hemoglobin oxygen transportation.
So, basically, it uses copper because it lives in a cold environment with less oxygen than us.
And we use iron because its warmer and oxygen is more freely available!
