I think it'd be cell, tissue, organ, organ system, organism.
I hope this helps!
Probability: The chance of something happening and the likelihood of a particular event happening.
Out of the choices given, the mechanisms that drives evolution is natural selection. The correct answer is B, natural selection.
Is this a question? I’m pretty sure this is not one
Continuous conduction takes place in unmyelinated axon.
Explanation:
Based on the presence and absence of myelin sheath, the neurons had been classified as myelinated and non-myelinated neurons respectively.
In myelinated neurons the transmission of impulse takes place only at the non myelinated region called nodes of Ranvier. Due to this, the conduction in Myelinated neuron is saltatory.
The conduction in non-myelinated neuron takes place throughout the length of axon and it is continuous.
Saltatory conduction is faster than continuous conduction.
