1. Consider the membranes illustrated in Model 1. Circle a section of the mitochondria below where this site might be located.

Mitochondria is the power house of the cell.

Explanation:

Mitochondria are double membrane cell organelles. They are mostly found in the eukaryotic organisms. They are a source of power house of the cell. They help in powering various biochemical reaction of the cell by generating chemical energy.

They are found in the body cells.

The electron transfer chain is mainly located at the inner mitochondrial membrane.  At the inter-membrane spaces of mitochondria, higher concentration of hydrogen are found.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
