What is 3.5 Billion years ago?
This organic compound has many important functions including muscle tissue building, immune response, and regulating chemical reactions.
What is a protein?
These organelles are responsible for protein production within a cell.
What are the ribososmes?
This compound always contains carbon and usually nitrogen, oxygen, and hydrogen.
What is an Organic Compound?
