Answer:
A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is usually compact. The axon and dendrites are filaments that extrude from it. Dendrites typically branch profusely and extend a few hundred micrometers from the soma. The axon leaves the soma at a swelling called the axon hillock (<em><u>the axon hillock also has the greatest density of voltage-dependent sodium channels. This makes it the most easily excited part of the neuron and the spike initiation zone for the axon</u></em>) and it branches but usually maintains a constant diameter. At the farthest tip of the axon's branches are axon terminals, where the neuron can transmit a signal across the synapse to another cell.
<em>In general, dendrites receive the electrical signal from other neurons, and this signal is transmitted over long distances from the axon.</em>
Like all animal cells, the cell body of every neuron is enclosed by a plasma membrane, a bilayer of lipid molecules with many types of protein structures embedded in it. A lipid bilayer is a powerful electrical insulator, but in neurons, many of the protein structures embedded in the membrane are electrically active. These include ion channels that permit electrically charged ions to flow across the membrane and ion pumps that chemically transport ions from one side of the membrane to the other to generate the action potential that generates the electrical signal. They also have a highly developed synthetic apparatus for the production of neurotransmitters
Answer:
In studying the origin of the universe, one of the primary unanswered questions is <u>what came before the big bang.</u>
Explanation:
The big bang theory can be described as a theory which scientists have proposed to explain how the universe came into existence. This theory predicts how the extremely hot temperatures and dense atmosphere might have given rise to the stars and the galaxies.
Scientists have no idea what happened before the big bang theory. Some scientists predict that there might be another universe which collapsed before the big bang theory. While other scientists claim that there was nothing before the big bang.
Answer:
The near-UV CD range (>250 nm) of proteins delivers info on the define configuration. The indications found within the 250–300 nm section are because of the engagement, dipole alignment and also the environment of the encircling atmosphere of the essential amino acid, tyrosine, aminoalkanoic acid (or S-S disulfide associations) and essential amino acids. In contrast to far-UV CD, the near-UV CD variation can't be allotted to any specific 3D configuration. Relatively, near-UV CD varieties offer essential info on the character of the prosthetic teams in proteins, e.g., the pigment teams in hemoprotein and cytochrome.
Answer:
left ventricle
Explanation:
left ventricle pumps oxygen rich blood to the body (away from the heart, so through the arteries)
Answer:
The internal membrane known as the Cristae is collapsed. The folds of the inward layer or the Cristae give an expansion in the Surface Territory which gives the Mitochondrion more areas for ATP( the vitality cash) creation to happen
