The culprits for the degradation of local biological communities on Macquarie Island are the rabbits, rats,mice and cats that were non-native species were introduced by humans.
The introduction of non-native species to Macquarie Island was responsible for severely degrading the local biological communities, including the vegetation, birds, and invertebrates that were native to the island. The introduction of rabbits, rats, cats and mice led to the loss of native plants, while cats and pigs preyed on native birds and invertebrates. These introduced species caused extensive damage to the local ecosystem, resulting in the loss of native species and the decline of the island's biological diversity.
The new species competed for resources and habitat, and often preyed upon the native species. This had a devastating impact on the local ecosystem, and led to the decline of many native species. The introduction of rabbits was particularly damaging, as they caused widespread destruction of the native vegetation. This had a knock-on effect on the birds and invertebrates that depended on that vegetation for food and shelter. The decline of the native species has had a significant impact on the biodiversity of Macquarie Island, and has resulted in the loss of many unique and valuable species.
These species have wreaked havoc on the island, preying on native birds and other small animals, as well as destroying vegetation. The impact of these introduced species has been so severe that the island has been declared a World Heritage Site. In order to protect the remaining native species on the island, a eradication program was launched in the 1990s to get rid of the introduced animals. While this program has been successful in reducing the populations of these animals, they continue to pose a threat to the island's ecosystem.

A) this is an example of codominance when in the heterozygous form both genes manifest
we'll say that F-red feathers; f-white feathers
B)50% will have spotted feathers
c)0% wil have red feathers
The higher the frequency of a sound wave (shorter distance between waves), the higher the pitch of the sound. The lower the frequency (longer distance between waves), the lower the pitch of the sound.
The most accurate evidence of an evolutionary relationship between two organisms is a) similarity in DNA
Similarity in DNA is the strongest evidence stating the evolutionary relationship acquired from a common ancestor.
If the similarity in DNA sequence is more then it co-relates with a more closer evolutionary relationship between the two given organisms.
The similarities between the molecules of the biological structure shows the evolutionary relationship signifying the evolutionary ancestory.
The comparison in DNA sequences shows that how come various species and organisms are interconnected with each other and have a specific relation.
Biogeographical distribution also provides us information regarding the evolution of various species on the earth.
Placing the DNA sequences in a row above each other and finding out comparison between the characters is an important aspect of comapring the two given DNA sequences.
