Which structurres in a human transmit electrochemical messages?
Neurons are the structures in humans that transmit electrochemical messages. Neurons are specialized cells that generate and conduct electrical impulses, allowing for the transmission of messages throughout the nervous system.
Are humans single cell organisms?
No, humans are not single cell organisms. Humans are multicellular organisms composed of trillions of cells that work together to form tissues and organs. Each cell in the human body has a specific role and function.
Which organ system in humans is most directly involved in transport of oxygen?

Would humans live if there were no flies?
Yes, humans would still be able to live without flies. Flies play a role in ecosystems by helping with decomposition and pollination, but their absence would not directly impact human survival.
3 Why do nerve impulses need to travel faster in a Human than in an earthworm?
Nerve impulses need to travel faster in humans compared to earthworms because humans have more complex nervous systems with longer distances to travel. The faster transmission speed helps ensure rapid responses to stimuli and coordination of activities. Additionally, humans have larger bodies with a greater need for quick communication between distant body parts.
When humans exhale air passes from the trachea directly into the?
Air that is exhaled passes from the trachea directly into the larynx.
What is the function of sex cells in humans?

What is the function of a chickens trachea?
The function of a chicken's trachea is similar to humans. It is the windpipe, and it carries air into their lungs.
What is the finger like sac that has no known function in humans?
The appendix.
What finger like sac that has no known function in humans?
The appendix.
What cause humans to hear sound?
Sound travels through the air - causing the ear-drum to vibrate. This sends impulses to teh brain which is interpreted as sound.
