Answer:
Fragments of rock are squeezed and cemented together.
Explanation:
Answer:
false
Explanation:
as prokaryotic cells are the primitive types of cells so you do not have cell membrane
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.
They are both relatively strong bonds. however, hydrogen bonding is more stronger then ionic bonds and the h only bonds with the "f o n" elements. Ionic bods on the other hand are bonds between a metal element and a non metal element.
