<span>After release into the synaptic cleft, neurotransmitters interact with receptor proteins on the membrane of the postsynaptic cell,
causing ionic channels on the membrane to either open or close. When
these channels open, depolarization occurs, resulting in the initiation
of another action potential</span>
Answer:
Explanation:
1) The simplest structure is cubic system like simple cubic, body-centered cubic and face-centered cubic in the crystal system.
2) Yes, all minerals have crystal structures because minerals have definite crystal structure. Minerals are solids that are formed naturally through the inorganic processes. Some mineral properties are density, shape, color and hardness.
3) Minerals are the naturally occuring inorganic substances which have ordered atomic arrangement, they are not made by humans that's why we can't predict the specific structure of majority of minerals.
<u>Answer:</u>
<em>The true statement concerning complex multi-cellular organism is Bulk transport systems move substances faster than simple diffusion.</em>
<u>Explanation:</u>
<em>Bulk transport</em> is the mechanism that is used by the cells to transport the large quantity of small and tiny molecules and particles. Bulk transport works on the <em>mechanism of pressure gradient and single diffusion</em> is based on the concentration gradient.
The<em> transportation on single diffusion</em> is due to random motion of molecules but in bulk transport the solute and water is moved <em>together and in a faster pace. </em>
