Explanation:
Living organisms are linked to one another because they share common genetic material. However, the degree of similarity in genetic material varies among different organisms. This is because of the process of evolution, which leads to the development of new species with different genetic traits.
Here are some key points to consider:
- All living organisms are made up of cells, which are the basic structural and functional units of life. This is a common feature that links all living beings together.
- The genetic material of living organisms is encoded in DNA, which is made up of the same four nucleotide bases (adenine, guanine, cytosine, and thymine). This is another common feature that links all living organisms together.
- However, the way in which this genetic material is arranged and expressed varies among different organisms. For example, humans and chimpanzees share about 98% of their DNA, while humans and bacteria share only a small fraction of their DNA.
- This variation in genetic material is due to the process of evolution, which involves the accumulation of genetic mutations over time. Organisms that are more closely related share a greater degree of genetic similarity because they have diverged from a common ancestor more recently.
- The degree of genetic similarity between organisms can be used to construct evolutionary trees, which show the relationships between different species. This is an important tool for understanding the history of life on Earth and how different organisms are related to one another.
In summary, living organisms are linked to one another because they share common genetic material, but the degree of similarity in this genetic material varies among different organisms due to the process of evolution.
All living organisms are linked to one another because ______ .a)They ...
Explanation:
Living organisms are linked to one another because they share common genetic material to varying degrees. This is because all living organisms have descended from a common ancestor and have evolved through natural selection over millions of years. This means that even though different species may have different genetic material, they share many similarities due to their common ancestry.
The degree of genetic similarity between organisms depends on how closely related they are. For example, humans and chimpanzees share about 98% of their genetic material because they are closely related, while humans and bacteria share much less genetic material because they are more distantly related.
Other factors that link living organisms include their common cellular organization and the fact that they all share basic biological processes like DNA replication and protein synthesis.
In summary, living organisms are linked to one another because they share a common ancestry and many similarities in their genetic material and biological processes.
