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.
Answer:
Natural selection has been studied since Charles Darwing first started his research.
Explanation:
<em>Basically natural selection changes the frequency of traits. Left themselves in large , freely interbreeding populations, the frequency of traits will remain the same from generation to generation. The traits are often heritable, in living organisms, many characteristics are inherited, or passed from parent to offspring. </em>
<em>The reasons why we mightt not see a response to directional selection on such a trait are:</em>
- <em>More offspring are produced than can survive.</em>
- <em> Organisms are capable of producing more offspring than their environments can support. </em>
- <em>Offspring vary in their heritable traits. </em>
Answer:
answer is A, work cells
Explanation:
Work cells can be described or explained as the physical and strategic arrangements of resources , such as the workers, equipment and other materials that are needed or required in performing or carrying out tasks in a business environment.
The work cell has some many advantages such as improving the quality and speed of the work to be done, and subsequently reducing the cost implications.
In this case, the Wheeled Coach Ambulance plant as a business entity or company, has adopted the work cell protocol and this has made them the best in their specialized industry.
The answer is landscape worker!
