when the fatty acid chain has no double bonds, it means that the fat molecule is
______.
unsaturated
saturated
unstable
no longer usable in our body

Explanation:

In biochemistry (a subfield of Biology, which is part of Natural Science), a saturated fat molecule has fatty acid chains with no double bonds (all carbon atoms are "saturated" with hydrogen atoms). Unsaturated fats have one or more double bonds. "Unstable" and "no longer usable" are incorrect as the absence of double bonds doesn't imply these; saturated fats are usable (e.g., in energy storage).

Answer:

B. saturated
