The biological levels of organization range from a single cell all the way up to the biosphere in a highly structured hierarchy.
The biological hierarchy includes: cells, tissues, Organs, organ systems, and organisms. Consider each of the pairs shown below select all that correctly paired the level with an appropriate example. A) organ: heart
B) cell: neuron
C) tissue: blood
D) organ: muscle
E) organ system: small & large intestines, stomach, pancreas, gall bladder
