How do scientists know the age of the california redwood?
Two methods: - radiocarbon dating - dendrochronology
Why is a two kingdoms classification system no longer used by scientists?
Lately scientists have found many species that they are not sure what to classification as because really they could be either, so they have the options to make more in-between kingdoms, or to just classificate them as living and nonliving organisms
What two methods of cataloguing books are the most common?
The two most common methods of cataloging books are the Dewey Decimal Classification system, which organizes books by subject, and the Library of Congress Classification system, which categorizes books by topic and author.
What are two methods that scientists use to get the data needed to make maps?
Two methods that scientists use to get data for map making are remote sensing, which involves collecting data from satellites or aircraft, and ground surveys, where researchers gather data by physically visiting and measuring locations on the ground. These methods help scientists create accurate and detailed maps for various purposes, such as studying landscapes, environment, and planning.
What is a two-kingdom classification system no longer used by scientists?
The two-kingdom classification system grouped organisms into the categories of plants and animals. It is no longer used by scientists because it did not accurately reflect the diversity of life on Earth and failed to account for the many different forms of organisms that exist.
What are two kinds of classifying?
Two common methods of classifying are hierarchical classification and categorical classification. Hierarchical classification organizes items into nested categories based on shared characteristics, often resembling a tree structure. Categorical classification, on the other hand, groups items into distinct categories without a specific order, allowing for quick identification based on predefined criteria. Both methods are widely used in fields such as biology, library science, and data organization.
How do you name two methods scientist use to obtain empirical evidence?
Two methods scientists use to obtain empirical evidence are experimentation and observation. Experimentation involves manipulating variables in a controlled environment to test hypotheses, while observation entails systematically watching and recording phenomena in their natural settings. Both methods help scientists gather data that can be analyzed to draw conclusions about the natural world.
Which two levels of animal classification do scientist use the most?
Scientists use the genus and species levels of animal classification most frequently because they provide the most specific information about a particular organism. This system helps scientists accurately classify and differentiate between different species.
How does analysis of DNA help scientists establish an evolutionary classification scheme?
Analysis of DNA helps scientists establish an evolutionary classification scheme by comparing the genetic sequences of different organisms. The more similar the DNA sequences are between two species, the more closely related they are believed to be. By studying the similarities and differences in DNA, scientists can determine how different species are related to one another and create a classification scheme based on their evolutionary relationships.
What are the two problems with older methods of classification?
Older methods of classification often rely heavily on observable characteristics, which can lead to inaccuracies due to convergent evolution, where unrelated species evolve similar traits. Additionally, these methods typically do not account for genetic relationships, resulting in classifications that may not reflect true evolutionary lineages. This can misrepresent the diversity and connections among organisms, hindering our understanding of biodiversity.
What are the classification of liability?

What happens if two organisms share the same classification level?
If two organisms share the same classification level, it means they are more closely related in terms of evolutionary history. They likely have more recent common ancestors and share more similar characteristics compared to organisms that are classified in different levels. This classification system helps scientists understand the relationships between different organisms.
