As we have mentioned before each radioactive isotope has its own decay pattern. Not only does it decay by giving off energy and matter, but it also decays at a rate that is characteristic to itself. The rate at which a radioactive isotope decays is measured in half-life. The term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. Half-lives for various radioisotopes can range from a few microseconds to billions of years. See the table below for a list of radioisotopes and each of unique their half-lives.

Match the type of of evidence for evolution with the correct example. analogous structures vestigial structures homologous struc
gogolik [260]

• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.

Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.

• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.  

Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species.  Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.

• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.

The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.

• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.  

Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.

Why are both biotic and abiotic features important in ecosystems and biomes?
Sati [7]

Answer:

Hope this is helpful! Sorry if my answer is choppy.

Explanation:

Biotic and abiotic features are both important in ecosystems because for example, a biotic factor like a plant, relies on an abiotic factors like the rain and the sun. If the rain were non existent, then the plants would no longer be alive causing a chain reaction in the food system. Biotic factors like plants and animals that are non existent can also cause negative effects in biomes and ecosystems.
