A. Liver: The liver is a large, reddish-brown organ in the right upper quadrant of the abdomen, just beneath the diaphragm. If the diagram is pointing to this area, especially the largest solid organ on the right side, it matches the liver’s location and size.

B. Stomach: The stomach is located mainly in the left upper quadrant, inferior to the diaphragm and to the left of the liver. It is smaller and has a J-shaped structure, so it would not match if the pointer is on the large right-sided organ.

C. Spleen: The spleen is located in the left upper quadrant, lateral to the stomach and posterior to the rib cage. It is much smaller than the liver and not in the right-sided position indicated.

D. Diaphragm: The diaphragm is a dome-shaped muscle that separates the thoracic and abdominal cavities. If the pointer is on the muscle just beneath the lungs, it would be the diaphragm, but here it’s on a large organ, not a muscle.

A. The chemical properties of the hormone:
Chemical properties determine solubility and transport but do not alone determine cellular response.

B. The presence of a receptor for that particular hormone:
A hormone exerts its effects only on cells that express specific receptors for that hormone.

C. The location of the gland that secretes the hormone:
Hormones are typically secreted into the bloodstream and can act at distant sites; gland location does not determine target cell responsiveness.

D. The location of the target cells in the body:
Location doesn’t matter unless the cells have the appropriate receptors.

E. The site where the hormone is secreted:
The site of secretion is irrelevant to whether a target cell can respond; it must have the receptor.
