Answer:

Neurotransmitters are released from axon terminals via exocytosis

Explanation:

Dendrite is the receiving part of the presynaptic neuron, while axon is the transmitting part of the neuron. So, after initiation, action potentials travel down axons to the terminals. Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells (exocytosis of the vesicle's content). Neurotransmitter ACh (from the vesicles) binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.

What happens to a cell when immersed in a beaker of distilled water?
stich3 [128]
You haven't specified if which type of cell you are referring to. There are many types of cells and each cell would have different reactions when immersed in a beaker of distilled water. So let us take for example, the red blood cell. A distilled water is hypotonic compared to the solution contained within the cells' membranes. Therefore, t<span>he distilled water will diffuse into the red blood cells and cause them to burst. Hope this answers the question.</span>

seraphim [82]

Answer:

east to west

Explanation:

The stars and moon are the celestial bodies which are located at distant.

The distance of stars vary but moon and sun remain same. As our Earth rotates at its own axis, other celestial bdies seem to move.

As Earth spins from west to east, the stars and moon seems to move from east to west direction at night and same with Sun, it also seem to move from east to west.

Hence, the correct option is east to west.

During DNA Replication, a DNA strand that has the bases 3'ATACGC5' produces a strand with the bases
Gemiola [76]

During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'  

Answer: Option B

<u>Explanation:</u>

The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.

Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
