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. 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. a cells structure allows it to carry out a specific function.

Explanation:

• The statement "All cells in the human body are small and round" is false. Neurons, for example, have a long extension (axon) and are not small and round.
• The statement "The human body contains different types of cells" is true. There are various cell types like neurons, adipocytes, etc.
• The statement "Adipocytes have a long axon to communicate with other cells" is false. Axons are a feature of neurons, not adipocytes.
• The statement "A cell's structure allows it to carry out a specific function" is true. For instance, the long axon of neurons helps in sending and receiving signals.

Answer:

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