The rate of firing of the postsynaptic neuron depends on the amount of input it receives from the presynaptic neuron. a. excitation b. inhibition c. equalizing d. both excitation and inhibition

The correct answer is d. both excitation and inhibition.

There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
