Answer:
Finally, the chemical messenger is taken back into the presynaptic neuron, ready to be used again. As levels of the neurotransmitter in the synapse decrease, the stimulation of the postsynaptic nerve ends.
Explanation:
The synapse is the space between two neurons. Through this space, neurons communicate.
An action potential causes the release of neurotransmitters from the presynaptic neuron; if there are enough of these specific neurotransmitters to bind to receptors on the postsynaptic neuron, they do and an action potential is now generated on this neuron.
This communication between two neurons must end once it's happened. In order for it to end, the synapse must be free of neurotransmitters. One mechanism to do so is for the neurotransmitters to be taken back into the presynaptic neuron.
The answer would be the species’ niche. A niche includes all the interactions of a species.
Because plants go through a cycle(the cycle is seed, seedling, plant, flower and tree.) and it takes time for the plant food, water, and nutrients to go though the plant.
The six pedigree symbols with the corresponding names of the individuals in Rose's family will be like 2nd - Rose; 7th - Becky; 4th - Dave; 8th - Mike; 10th - Pat and 13th - Erik.
The second will be Rose because Becky's father, who is Rose's husband, is healthy and Jess, Becky's mother, has myotonic dystrophy. The seventh person is Becky, who has myotonic dystrophy and is married to Mike, who is healthy. Dave, who has myotonic dystrophy, is the fourth.
Mike, who is normal and married to Becky who has the condition or is impacted, comes in at number eight. Pat (unaffected), the daughter of Dave and Mary, is ranked tenth. Erik (affected), the son of Becky and Mike, is the 13th person on the list.
Myotonic dystrophy is an autosomal dominant condition that is passed vertically from parents to offspring. This illness affects both men and women equally and does not pass down through generations.
