Response to stimulus without the central nervous system (CNS) differs from a response initiated by a reflect because the former
A undergoes depolarization
B has greater speed
C includes interpretation of information
D does no release acetylcholine
Botulism is a serious form of food poisoning. It results when a substance called botulinus toxin, produced by bacteria prevents the released of acetylcholine of motor nerve fibres. The effect is
A contracting of all skeletal muscles, resulting in paralysis
B the inability of ATP to be released
C a decrease in PH due to build up of lactic acid
D the failure of muscles to be stimulated
The all or non principle of nerve action refers to the conditions in which

B all stimuli reaching nerve cells activate them, no stimulus goes unheeded
C a stimulus depolarizes all the neuron in a nerve or no neurons at all
D a stimulus activates a nerve cell to function to capacity of not to function at all
