Answer:
A. motor neurons; peripheral nervous system
Explanation:
Motor neurons carry signals from the peripheral nervous system to the muscles. This causes the muscles to either relax or contract. Note that the peripheral nervous system consists of neurons and parts of neurons outside of the central nervous system which consists of the brain and spinal cord. When signals are transmitted between the motor neurons and peripheral nervous system, this causes a response to stimulus in the muscles which would either, relax or contract.
the answer is B) The same number of dots would appear in the diagram for carbon.
The answer is C because there is no inference in the statement like the others.
The epidural anesthesia is a method of pain relief, which is used during the labor pain. It is a well known regional anesthesia. It works by acting as an analgesic, which means a substance that eases the pain, a complete anesthesia or loss of feeling does not occur in the case of epidural anesthesia. It blocks the nerve signals from the lower spinal segments. It is also known as spinal epidural anesthesia or lumbar epidural anesthesia.
Hence, the black can be filled with lumbar.
The answer is; medulla oblongata and pons.
In this region of the brain, there are chemoreceptors that can detect changes in the pH of the blood. These are called central chemoreceptor. There are also chemoreceptors in the arteries called peripheral chemoreceptors. When these chemoreceptors detect a drop in the blood PH (due to increased dissolved carbon dioxide in the blood), the depth and rate of breathing is increased in the lungs.
