A separate body structure that performs a specific function and is composed of two or more different tissues is a(n)?

1. Cell

2. Tissue

3. Organ

4. System

The correct answer is: Organ

The correct answer is an organ. An organ is defined as a structure that is made up of two or more types of tissues that work together to perform a specific function in the body. Each organ has a distinct role and is crucial for maintaining the body's overall function. For example, the heart is an organ composed of muscle tissue, connective tissue, and nervous tissue, all working together to pump blood throughout the body. A cell, on the other hand, is the smallest unit of life and does not consist of multiple tissues. A tissue is a group of similar cells that perform a specific function, but it alone does not meet the criteria of being composed of two or more different tissues. A system refers to a group of organs that work together to perform complex functions, but it is a broader term than what is described in the question. Therefore, the definition provided perfectly aligns with the characteristics of an organ.
