Introduction:
The most important function of the nervous system is to maintain the body’s temperature, ion balance, and other conditions within optimum levels. The

Answer to Problem 1MCQ
Correct answer:
The peripheral nervous system receives sensory stimuli, whereas the central nervous system integrates sensory information. Hence, the correct answer is option a..
Explanation of Solution
Reason for correct answer:
Option a. is given as “receives sensory stimuli; integrates sensory information.”
The central nervous system consists of two organs: brain and spinal cord, whose function is to integrate sensory information and coordinate the response of the body. The peripheral nervous system transmits information between the central nervous system and the rest of the body.
Reason for incorrect answer:
Option b. is given as, “produces sensory information; produces movements.”
The central nervous system is used for integrating sensory information and for coordinating the body’s responses, while the peripheral nervous system help in processing changes in the external and internal environment. Hence, option b. is incorrect.
Option c. is given as, “integrates sensory information; receives sensory stimuli.”
The central nervous system helps in integrating sensory information, and the peripheral nervous system helps in transmitting the information between the central nervous system and the other parts of the body. Hence, option c. is incorrect.
Option d. is given as, “coordinates voluntary actions; coordinates involuntary actions.”
The central nervous system builds up the peripheral nervous system and conducts information from the brain and spinal cord to the rest of the body. The peripheral nervous system controls both voluntary and involuntary actions. Hence, option d. is incorrect.
Hence, the options b., c., and d. are incorrect.
The sensory information is integrated by the central nervous system; whereas, the sensory stimulus is received by the peripheral nervous system. Thus, the correct option is a..

- Did your intake of vitamin C meet or come very close to the recommended amount? yes noarrow_forwardWhich of the following statements about hydration is true? Absence of thirst is a reliable indication that an individual is adequately hydrated. All of these statements are true. Although a popular way to monitor hydration status, weighing yourself before and after intensive physical activity is not a reliable method to monitor hydration. Urine that is the color of apple juice indicates dehydration. I don't know yetarrow_forwardThree of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes.
