AA whole organism
BA single organ
CAn organ system
DAnother tissue
Answer & Solution
Correct answer: B. A single organ
1. Cells of one kind that interconnect and share a function make a tissue.
2. Several tissues combined make an organ, such as the stomach, heart or brain.
3. Only when several organs are combined does an organ system appear, so an organ system is one step further up.
4. The level formed directly by combining tissues is a single organ.
