The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.
Answer:
im pretty sure its A. ATP was a thing talked about a lot on this topic
Explanation:
Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.
1. Number of postsynaptic neurons
In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.
2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.
3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.
4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.
<h3>Steps in order fro the formation process of urine</h3>
3) Blood enters the kidneys through the renal artery and branches to reach the glomerulus.
1) Nephron tubules secrete waste products into collecting tubules.
4) The filtrate travels through the renal tubule and useful substances are reabsorbed into the blood.
2) Pressure of the blood forces water and dissolved substances through capillaries and into the Bowman's capsule.
<h3>Explanation</h3>
The Glomerulus filters water and other substances from the bloodstream. According to the requirement of the body, reabsorption moves nutrients and water back into the bloodstream. Urine actually is made up of 95% of water and the other nutrients are waste ions and hydrogen ions.
