The correct statement regarding a chemical synapse is sodium ions enter the axon terminal to signal release of neurotransmitters i.e., option B.
<h3>What is chemical synapse?</h3>
Chemical synapses are links created by two neurons or a neuron and a non-neuronal cell (muscle cell, glandular cell, sensory cell).
The synaptic complex is the basic non-reducible unit of each chemical synapse, representing the bare minimum for efficient chemical synaptic transmission.
The correct statement regarding a chemical synapse is sodium ions enter the axon terminal to signal release of neurotransmitters.
Thus, the correct option is B.

Answer:
they share electrons and bond forming lithium floride
Answer:
1. (c)
2. (a)
3. (c)
4. (b)
5. (d)
1. (a)
2. (b)
3. (c)
Explanation:
<u>OBSERVATION TYPE</u> :-
1. The elements can be divided into 3 major groups metals, non- metals and metalloids. The rest of the options are also the names of some groups yet fail to be then correct answer. If you were asked to define 18 groups that exist in the periodic table then you'd have selected them. (r u getting me?)
2. Group 1 elements are known as alkali metals
3. Group 2 elements are called alkaline earth metals
4. Group 13 is called Boron Family
5. These are non-metals
i'd have selected Nobel gases had not Hydrogen been there. Excluding Hydrogen all are nobel gases.
<u>C</u><u>O</u><u>N</u><u>C</u><u>L</u><u>U</u><u>S</u><u>I</u><u>O</u><u>N</u><u> </u><u>:</u><u>-</u>
1. The modern periodic table groups the elements into vertical columns, groups, and horizontal rows, groups.
2. Since the question is asking the harmful changes in metals that take place upon reacting with acids, it'll be option (b). as the metals corrode upon being treated with acids which is not of good use to us. the last two options talk bout the uses of this process which wont be "harmful", so the answer is only option (b)
3. Protective layering of various metals like Zn, Al helps prevent corrosion in metals.
Answer:
Natural selection is the process in which survival of the fittest, a concept by Charles Darwin suggests that animals adapt to better suit their needs. Those who survive are the "fittest" and breed children with the trait until the unfit die out. He saw this with the Galapagos finches. there used to be 1 kind of finch, now there are 14.
I hope this helps u!
pls give a brainliest( had 40 down to 2 for no reason) and a thx ;)
i will thank u for it via profile thanking and comments
Answer:n energy transfer, happens from one object to another without changing its form. For example, when you fill a pot of water and sit it on the stove, the water continues to heat until you turn it off. While in a energy transformation, the energy changes forms such as Chemical, kinetic.
