Answer:
Australia has so many genetically distinct organisms because it has been separated from other bodies of land for a very long time. This has given species in Australia a long time to evolve independently from species in other areas of the world.
The Miami blue butterfly and the Florida scrub jay are both endemic to the State of Florida. The Miami blue butterfly is a critically endangered species while the Florida scrub jay is a threatened specie. Both of their numbers are <span>dwindling and efforts are being made to protect their continue existence.

Choice C. Educated guess or a prediction that can be tested, based on limited evidence.
Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then
So it has to be D
A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction.
