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.
D) All of these
Reason: All of these could be used as an alternative energy resource to help minimize air
pollution in this community.
Solar energy can be captured with solar panels and used to produce electrical energy or
to heat systems directly. Wind energy can be captured using wind turbines, which turn
generators to produce electricity. Hydroelectric energy can be produced by using the
energy of running water to turn generators.
Although all types of alternative energy resources have various advantages and
disadvantages, these three all share the advantage of not producing air pollution
Hope this helped. :)
The right option is; B. 7 major plates and many smaller plates
In the plate tectonics theory, the lithosphere is divided into 7 major plates and many smaller plates.
The plate tectonics theory is a scientific theory that explains that the Earth's lithosphere which is the rigid outer layer of the earth is made up of seven large continental and ocean sized major plates and many minor smaller plates. The movements of the plates are relative to each other and it usually ranges from zero to 100 mm per year. The interactions of the plates along their boundaries are thought to be the primary cause of majority of the earth’s seismic and volcanic activity.
It doubles, so the answer is 8 chromosomes.
D. She should look for ovals full of green dots called chloroplasts.
