Explanation:

Question 4

The gallbladder is an organ involved in digestion, and it is located within the abdominal cavity. The pelvic cavity holds reproductive and urinary organs, the dorsal cavity holds the brain and spinal cord, and the mediastinum is in the thoracic cavity (holds heart, etc.). So the gallbladder lies in the abdominal cavity.

In biological organization, a tissue is a group of similar cells that work together to perform a specific function. Organelles are structures within cells, organ systems are groups of organs, and an organism is a whole living entity. So when similar cells specialize for a function, it's a tissue.

Medial means closer to the midline of the body. The neck is closer to the body's midline than the right shoulder (which is lateral, away from midline). Inferior is lower, deep is internal. So the neck is medial to the right shoulder.

Answer:

A. abdominal cavity.
