Answer:
The trachea serves as a passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
Answer:
<h2>As transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location, post-transcriptional processing in eukaryotes. </h2>
Explanation:
The transcription and translation occurs in different location in eukaryotes, while in prokaryotes, both the processes occurs at same location and can be co-translation.
As, in eukaryotes, the transcription occurs in the nucleus and then this transcript have to move in the cytoplasm to translation, so before reaching in the cytoplasm, various modifications occur in this transcript known as post transcriptional modification or processing ( include 5' capping, 3' poly-adenylation and RNA splicing).
As, in prokaryotes, both transcription and translation occur at same place so there is no time for modification for transcript because translation starts as the transcription is still going on.
Answer:
Areas where the myelin sheath has degenerated
Explanation:
Multiple sclerosis is a disease of the nervous system where the myelin sheath is damaged, and impairs its ability of conducing signals in the affected nerves, causing serious deficiencies in many life aspects (movements, sensations, cognition etc).
<span>The probability of an action potential being propagated from neuron to neuron is increased when the postsynaptic neuron's signal is in an excitatory state. During this state, the action potential of a presynaptic neuron increases the probability of transmission of a signal to the postsynaptic neuron.</span>
