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.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
