Answer from: gg808

Many factors have been shown to affect reaction times, including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual. Sensory neurons convert a stimulus into an electro-chemical signal, which flows the length of the

sensory neuron(s), then through a neuron or neurons of the central nervous system, and then

through the length of the motor neuron(s). Generally, motor neurons will cause a muscle to

contract or a gland to secrete a substance. Reactions that involve only the receptor, the spinal

cord, and the effector, are faster than those which involve processing in the brain. Reactions

which only travel to, through, and from the spinal cord are often called spinal reflexes or cordmediated reflexes; withdrawing one’s hand from a hot stove is an example of such a reflex.

In ‘simple reaction time’ experiments, there is only one stimulus and one response. Catching a

dropped stick, or hitting a button when a light changes are examples.

In ‘recognition reaction time’ experiments, there are symbols to respond to and symbols to be

ignored. There is still only one correct stimulus and one response. An example would be

catching a dropped stick with a word cue, while having to ignore other spoken words which are

not cues.

In ‘choice reaction time’ experiments, there are multiple stimuli and multiple responses. The

reaction must correspond to the correct stimulus. Typing a letter which matches a printed letter

prompt is an example of this type of experiment.

Answer from: Quest

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.
