1. The following statement is similar to those you might see on exams. Write a paragraph of 3-5 sentences describing 1) whether
12345 [234]

Answer:

Correct

Explanation:

The statement is correct because, during the chemical synapses, the transmission of information takes place when the presynaptic neuron releases a <u>neurotransmitter</u> that binds to a specific receptor located in the postsynaptic membrane. The release of these neurotransmitters happens almost always when the action potential reaches the synaptic terminal.  In the membrane of the synaptic terminal, the number of Ca++ voltage-depended channels is greater than in other parts of the membrane, hence, when the action potential depolarized the membrane, the channels open and the Ca++ defuses actively into the cell. The intracellular concentration of Ca++ is very high and this strong and rapid increase, facilities the depolarization of the membrane and <u>allows the release of the neurotransmitter to the postsynaptic membrane</u>.

What is the difference between weathering and erosion? (Site 1).
olchik [2.2K]

Answer:

Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.
