What is the function of an organ system? (1 point)
The function of an organ system is to work together to perform a specific set of functions necessary for the survival and well-being of an organism. These functions can include processes such as digestion, respiration, circulation, excretion, and reproduction.

How are muscle cells and bone cells similar?
Muscle cells and bone cells are similar in that they are both types of specialized cells found in the human body. They are both derived from stem cells and have specific functions within the body. Additionally, both muscle cells and bone cells are considered part of a connective tissue. However, in terms of structure and function, muscle cells and bone cells differ significantly. Muscle cells, also known as muscle fibers, are responsible for contraction and movement, while bone cells, such as osteoblasts and osteoclasts, are involved in the formation and maintenance of bone tissue.

What is the term for changes in the internal or external environment that cause a response?
The term for changes in the internal or external environment that cause a response is stimuli.
How do signals from sensory neurons reach motor neurons?
Signals from sensory neurons reach motor neurons through a process called synaptic transmission. When a sensory neuron detects a stimulus, it generates an electrical impulse called an action potential. This action potential travels along the sensory neuron's axon until it reaches the synapse, which is a small gap between the sensory neuron and the motor neuron. At the synapse, neurotransmitter molecules are released from the sensory neuron and diffuse across the gap. These neurotransmitters bind to receptors on the motor neuron, triggering the generation of a new action potential. This action potential then travels along the motor neuron, leading to the contraction or movement of muscles or the secretion of glands, resulting in a response to the stimulus.
