Answer:
The correct order would be
Sensory receptors in the arteries detect low oxygen levels.
↓
Sensory neurons generate an impulse.
↓
The central nervous system relays an impulse to certain brain regions.
↓
The brain sends signals through motor neurons.
↓
Isabel's breathing rate increases.
The working of the nervous system can be summarized as:
The receptors receives the stimulus which then send signals to the brain with the help of sensory neurons.
For example, sensory receptors in the arteries detect the low oxygen levels after which sensory neurons send the signals to the brain.
The stimulus or information is processed in a specified region of the brain which then sends the signals to the effector organ via motor neurons.
The action or reaction is generated at the effector site such as an increase in the breathing rate of Isabel in this case.
Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.Your muscular system is closely connected to the nervous system.
Answer:
Because most natural environments harbor a stunningly diverse collection of microbial species. Within these communities, bacteria compete with their neighbors for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microbes. Additionally, a growing body of theoretical and experimental population studies indicate that the interactions within and between bacterial species can profoundly impact the outcome of competition in nature. The next challenge is to integrate the findings of these laboratory and theoretical studies, and to evaluate the predictions they generate in more natural settings.
