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.
Incorporate more schools that serve breakfast.
The Department of Health and Human Services in the US has proposed a program called Healthy People 2020 to encourage the prevention of acute and chronic illness for all US residents.
One of the more than 1300 specific goals of Healthy People 2020 is to increase the number of schools that serve breakfast. This is a crucial goal because, regrettably, not all parents provide their kids with a healthy breakfast because of financial hardship, carelessness, etc.
Children would benefit from breakfast being served at school either for free or at a reduced cost since they would start the day with nourishment and better health and nutrition from a nutritious breakfast.

Cells specialize to form specific tisue and organs because all cells have the same DNA. stem cells can develop into every type of cell inside the body.The cell is the basic unit of structure and function in all living organisms.
Explanation:
Ffeosol sulfate is an iron supplement.. children are susceptible to an overdose..they will get hard stools, push excessively to remove stools,
this depends on the child's weight, and if they hav had lost or gained weight during prognosis. if under 20lbs, they should get 5mil(1tsp) ..
if over 20lbs. should get 2 tsp..
guessing that child ingested 2oz that would equal 4 tsp of iron..
3 tsp = 1 tablespoon, so child ingested 1 & a half tsps of iron...
dont think it's dangerous, but should watch 4 reactions...
