Receptor, afferent neuron, control center, efferent neuron, effector muscle (the options are not given in the correct way therefore the options are arranged in sequence)

Explanation:

Reflex arc refers to the neuronal pathway which is activated during the reflex or emergency actions in the body.

The reflex arc pathway is a very fast response as it shortens the time of the neuronal pathway.

When the receptor senses the reflex stimuli, it immediately generates the signals and transmits them to the spinal cord through the afferent or sensory neuron. When the signal reaches the spinal cord then the signals are perceived by the interneurons or control centre of the spinal cord and then transmit the response to the effector muscle through the efferent neuron or the motor neuron. This whole pathway is followed in just a few milliseconds.

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.
