1. which of the following is formed when a group of tissues works together to perform a common function?

○ a. brain
○ b. organ system
○ c. organ
○ d. body

□ mark for review (will be highlighted on the review page)

Explanation:

To solve this, we recall the levels of biological organization. Tissues are groups of similar cells. When different tissues work together for a common function, they form an organ. Let's analyze each option:

• Option A: The brain is an example of an organ, not the general term for what's formed by tissues working together.
• Option B: An organ system is a group of organs working together, not tissues.
• Option C: By definition, an organ is formed when a group of tissues work together to perform a common function. This matches the description.
• Option D: The body is the entire organism, which is made of multiple organ systems, not directly from tissues.

Answer:

C. Organ
