I am not sure, but to me it sounds that this is important because human populations are sometimes concentrated in areas that are lacking resources. Although, all of the given options may be correct.
Answer:
The right order is
incomplete dominance ==> 2
polygenic inheritance ==> 3
codominance ==> 1
Many physical characters depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
Codminance: The phenotype of each allele is expressed simultaneously in heterozygotes.
Incomplete Dominance: An intermediate phenotype is obtained between the two dominant alleles.
Saltatory Conduction
During an action potential, the charge seems to “jump” from node to node rather than flow continuously down the axon, a process known as: Saltatory Conduction
.
Saltatory conduction is the faster distribution of action potentials across myelinated axons from one node of Ranvier (breaks in the wrapping of myelin insulation) to another node, which leads to increased speed of action potentials. The only area along the axon where ions are exchanged is the uninsulated nodes of Ranvier.
I think stratus clouds indicate possible precipitation
