Answer:
The correct match would be:
- Swallow - migration
- Tiger - sparse distribution—scarce
- Devil’s Hole pupfish - local endemic
- Humpback whale - sparse distribution—widely dispersed
Swallows are small migratory birds belonging to the family Hirundinidae found all around the world. Migrating swallows can cover around 200 miles in a day.
Tiger has become endangered species due to excessive hunting and habitat loss. It is estimated that only 3800 tigers are left in the wild.
Devil’s Hole pupfish is a species of a fish only found in Devils Hole which is a geothermal aquifer-fed pool located in Ash Meadows National Wildlife Refuge in Nevada city of the United States
The humpback whale or <em>Megaptera novaeangliae</em> is a species of baleen whale which is widely distributed in all major oceans including Pacific, Atlantic, and Indian oceans.
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
The answer for this question is "founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results" so it is letter A
The technicians ask the patients if they have any steel inside their body because the steel when subjected to a magnetic field they will become a magnet. since MRI produces a very large amount of magnetic field during its operation, then the still will be a magnet and it might hurt you
