Humans breathe in order to deliver oxygen to individual cells. Oxygen molecules are attached to and carried through the body by A. blood cells. B. the lungs. C. blood vessels. D. the diaphragm.

A. blood cells

Explanation:

Most oxygen carried in the blood is bound to the protein hemoglobin in red blood cells.

ok

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
