Which of the following describes the nervous system integrative function? a. responds to stimuli by gland secretion or muscle contraction b. analyzes sensory information, stores information, makes decisions c. senses changes in the environment

B. analyzes sensory information, stores information, makes decisions.

Explanation:

    The nervous system is the body’s main communication system; it gathers, synthesizes, and uses data from the environment.    The most basic unit of the nervous system is the neuron, which serves as both a sensor and communicator of internal and external stimuli.    The nervous system can be broken down into two major parts—the central nervous system and the peripheral nervous system.    The central nervous system, the main data center of the body, includes the brain and spinal cord.    The peripheral nervous system includes all of the neurons that sense and communicate data to the central nervous system.    The peripheral nervous system can be further divided into the autonomic system, which regulates involuntary actions, and the somatic system, which controls voluntary actions.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
