Question

neurons are brain cells with a long extension called an axon. since the axon is long, neurons can extend from the brain and spinal cord to other parts of the body to send and receive signals. select the true statements. a cells structure allows it to carry out a specific function. all cells in the human body are small and round. the human body contains different types of cells. adipocytes have a long axon to communicate with other cells.

Explanation:

• A cell's structure allows it to carry out a specific function: Neurons have long axons (structure) to send/receive signals (function), which shows structure - function relationship.
• All cells in the human body are small and round: Neurons are not small and round (they have long extensions), so this is false.
• The human body contains different types of cells: There are neurons, adipocytes, etc., so this is true.
• Adipocytes have a long axon to communicate with other cells: Axons are in neurons, not adipocytes (adipocytes store fat), so this is false.

Answer:

A. A cell's structure allows it to carry out a specific function, C. The human body contains different types of cells
