Answer:
The ability of body systems to increase their function, given the need to adapt, is known as the <u>physiologic reserve.</u>
Explanation:
The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
 
        
             
        
        
        
Answer:
The correct answer is - The cranial nerves and the spinal nerves.
Explanation:
The central nervous system or CNS includes the brain and the spinal cord of the nervous system where it takes sensory information, integrates, and responds accordingly. The spinal cord acts as a conduit for signals between the brain and the rest of the body.
Spinal nerves and crania; both play an essential role in taking sensory information and respond accordingly. Spinal nerves are nerves that help in sending motor, sensory, and autonomic signals between the CNS and the body. The cranial nerves supply information to the CNS and then from the CNS to the body.
Thus, the correct answer is - The cranial nerves and the spinal nerves.
 
        
             
        
        
        
Answer:
Molecules can move into or out of cells by the process of diffusion . Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.
