The statement which explains why muscle cells and skin cells do not look and act the same is this: THE GENES IN EACH TYPE OF CELL ARE BEEN EXPRESSED DIFFERENTLY.
All the cells in human's body has the same set of genes, this is because, all the cells in the body originated from a single fertilized egg. Even though all the cells in the body has the same origin, they are different from one another because, the cells use the same set of genes differently.
That the findings have been peer reviewed and been thought actual study <span />
Starting from the triggering action potential, the membrane potential in the neuron will propagate from the dendrites to the cell body then to the axons where synaptic vesicles are located. The action potential will trigger an influx of calcium into the axon then calcium will bind to proteins that will move the synaptic vesicles to the synaptic cleft. The membrane of the synaptic vesicles will eventually join the membrane of the synapse and then the neurotransmitters inside the vesicles will be "spilled" into the synaptic cleft.
The salmon is a key player in the food web whose removal may cause an imbalance in the whole ecosystem.
<h3>What is a food web?</h3>
A food web is a graphical diagram representing all connections between organisms in a given ecosystem.
Salmon represent the food for different types of animals in a food web, thereby their removal may cause serious harm to the balance of the ecosystem.
Salmon fish is a tertiary consumer because they eat herring which in turn eat zooplankton that eats phytoplankton.
