What type of conduction takes place in unmyelinated axons? What type of conduction takes place in unmyelinated axons? Continuous
Volgvan

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.

nydimaria [60]

Answer:

the higher the diversity, the higher the populations of all the

photosynthetic organisms

Explanation:

Diversity in plant allows random mating also known as panmixia. It allows plant have equal chances of being mated too by any among them creating variations in the population. It leads to less fixed gene, reduce genetic drift leading to an increases population as some lethal gene may be lost due to recombination of gene among individual plant.

Where there is no diversity some gene becomes fixed leading to perpetuation of some traits that may be harmful in a population but diversity allows for the generation of new gene and allele frequency within a population.
