Answer:The biodiversity of the islands has decreased.
Explanation: Galapagos Islands is located in an island in Equador, it is at this island that Charles Darwin carried out his biodiversity experiment. The island is known to contain a wide range of diverse species that are unique to the Galapagos Islands.
The biodiversity of the Island is been threatened in recent times due to destructive activities of Humans,people are introducing Alien species like the Goats now introduced into the farm by some farmers years ago, the dumping of refuse,the high rate of buildings coming up around the island and the influx of Tourists all these are making the Inherent species to find the environment unattractive any longer hence, they are going into extinction.
Answer:
B.The biodiversity of the islands has decreased
Explanation:
fyi i just got it correct
Answer:
1. directional selection
2. Hardy-Weinberg equilibrium
3. sympatric
4. This is allopatric speciation.
5. This is an example of stabilizing selection in a population because the organisms in the middle of the population have the best fitness for their environment.
6. The five conditions impacting this equilibrium are: mutations, nonrandom mating, genetic drift, migration, and natural selection.
7. Natural selection impacts single-gene traits because of the possible extinction of one trait or increase of another trait. If a trait is found to be not preferable in that environment, it could be eliminated through natural selection.
8. The total allele frequency in the Hardy-Weinberg equilibrium has to equal 1.:
from Penn Foster
When the relationships between species are mapped out, branches spread out from a common trunk, resembling a tree.
