Polyploidy is a major force in the evolution of both wild and cultivated plants. ... Some of the most important consequences of polyploidy for plant breeding are the increment in plant organs
Some scientists are studying a newly discovered microbe and determine that it consists of a single cell, lacking a nucleus. this organism could be <u>a bacterium.</u>
<u></u>
<h3>What do you mean by bacterium?</h3>
- Any of a large group of one-celled organisms that reproduce by fission or by generating spores, lack a cell nucleus, and occasionally cause disease.
- They are the most prevalent life forms on Earth, present in all living organisms as well as all climatic conditions.
<h3>What can be discovered in bacteria?</h3>
- Its gel-like matrix, which also contains other cell components like ribosomes, chromosomes, and plasmids, is made up of water, enzymes, nutrients, waste products, and gases.
- The cytoplasm and all of its elements are enclosed by the cell membrane.
- Bacteria do not have a nucleus that is contained in a membrane like eukaryotic (true) cells do.

Mass divided by volume is the correct answer
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.
