The amount of energy that is contained in a food or drink is measured in calories. Food items typically have calorie counts displayed on them, and wearables like the best fitness trackers let you keep track of how many calories you burn while engaging in various activities. There are some foods that often have more calories than others, such as fatty, fried, or processed foods. Other items, such fresh fruit and vegetables, typically contain fewer calories. While low-calorie items like diet Coke have no nutritional value, some healthful fruits and vegetables can have a high calorie content.

Zolol [24]

Answer:

The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.

Explanation:

Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
