In a hypothetical population of butterflies, a dominant mutation in an allele that controls wing color has resulted in purple sp

ots developing on the wings. The genetic change is heritable such that the offspring of butterflies who inherit at least one mutated allele will develop purple spots. The population of butterflies inhabits a windy field that contains many purple flowers. Individuals with purple spots are so well camouflaged on the purple flowers that they are eaten less frequently by predators. There are other fields with populations of the same species of butterfly nearby, but purple flowers are less prevalent in these nearby habitat areas. There are no borders between these fields and it is common for individuals from one population to be blown into another population by the wind. Despite the advantage the mutated allele confers to the butterflies in the field with many purple flowers, the mutated allele never occupies 100% of the gene pool and the population of butterflies always contains a mix of individuals with and without purple spots. What is the most likely explanation for why this trait does not spread entirely throughout the population

The movement of alleles into a population is called gene flow. The most likely explanation for why this trait does not entirely spread in the population is 'outside alleles enter the population through gene flow'.

Gene flow is caused by the migration and further reproduction of individuals in the population, or the transport of gametes from one population to another (e.g., the transport of pollen by pollinating bees).

Gene flow is an evolutionary force capable of modifying allele frequencies in a population.

In this case, despite the evolutionary advantage that the mutated allele confers to the butterflies, the frequency of this allele can not reach 100% due to the continued introduction of alleles from other populations (i.e., due to gene flow).

What makes arteries unique ?
ehidna [41]

Arteries are blood carrying vessels which have thick, elastic,  muscular walls, have no valves and in which blood flows under high pressure. The make up of arteries is unique to their function of transporting blood under high pressure. 

All arteries carry oxygenated blood from the  heart to all other parts of the body, with the exception of the pulmonary artery which carries de-oxygenated blood from the heart to the lungs. It is the only artery that transports blood which has not been oxygenated.

Zarrin [17]

Answer:

The correct answer is vasogenic edema.

Explanation:

A kind of cerebral edema in which the blood-brain barrier is disrupted is termed as vasogenic cerebral edema. It refers to extracellular edema that primarily influences the white matter through leakage of fluid from the capillaries.  

It is primarily witnessed surrounding the brain tumors, that is, both primary and secondary and the cerebral abscesses, however, some of the vasogenic edema may be witnessed around the developing cerebral hemorrhage and cerebral contusion.
