How is biochemical comparison different from other methods of determining evolutionary relationships?
Biochemical comparison involves analyzing genetic material or proteins to determine evolutionary relationships, while other methods (such as morphological comparison) may focus on physical characteristics. Biochemical data provides more precise and objective information about relatedness, as it is less influenced by external factors, such as environment or development, that can affect physical traits. Additionally, biochemical data can reveal similarities that are not evident based on external appearances.

What two things are compared when patterns of evolutionary relationships are constructed using molecular phylogenetic?
When constructing patterns of evolutionary relationships using molecular phylogenetics, researchers typically compare DNA, RNA, or protein sequences from different organisms. By analyzing similarities and differences in these molecular sequences, scientists can infer evolutionary relationships and determine how closely related different species are. This comparison allows for the construction of phylogenetic trees that visualize these relationships over evolutionary time.
How are evolutionary relationships determined?
Evolutionary relationships are determined by analyzing similarities and differences in genetic material (DNA) among different organisms. By comparing specific genetic markers or sequences, researchers can construct phylogenetic trees that show the evolutionary history and relatedness of species. These relationships are then used to understand the evolutionary processes and patterns that have shaped the diversity of life on Earth.
What is chromosome comparison?
Chromosome comparison is where the DNA of one species is compared to another. For instance, Scientists compare the remains of prehistoric animals to current organisms roaming the Earth in our modern day world.
What the different between kingdoms and phylogeny?
Kingdom was traditionally the highest level of classification for organisms until recently, when the concept of domains was introduced. There are five kingdoms: Animalia, Plantae, Protista, Fungi and Monera.A phylogeny is the evolutionary history of a species or group of species. They separate organisms by evolutionary relationships (clades), based on comparative cytology and the comparison of DNA, morphological characters, and shared ancestral and derived characters.
What type of molecular comparison would help to determine whether fungi are more closely related to plants or to animals?
Comparing the presence or absence of specific molecular markers, such as chitin in fungal cell walls or cellulose in plant cell walls, would help determine evolutionary relationships. Additionally, analyzing the genetic sequences of key genes involved in metabolic pathways unique to fungi, plants, and animals could provide insight into their relatedness. Phylogenetic analysis using these molecular data can help establish the evolutionary relationships between fungi, plants, and animals.
The number and structure of what can help to determine evolutionary relationships between species?
The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.

What is biochemical comparison?
Biochemical comparisons are limited to comparing two living life forms. Before the comparison can be made, you have to study the genetic relationship between the two living things.
What is the usefulness for phylogenetic trees?
The phylogenetic tree is used for the study of evolutionary Biology. The phylogenetic tree is a symbolic diagram that is meant to represent the similarity and differences of different species for comparison with common evolutionary relatives.
How does the comparison of monkey DNA and human DNA provide insights into evolutionary relationships between the two species?
By comparing the DNA of monkeys and humans, scientists can identify similarities and differences that provide clues about the evolutionary relationship between the two species. The more similar the DNA sequences are, the more closely related the species are believed to be in terms of their evolutionary history. This comparison helps scientists understand how monkeys and humans are related and how they have evolved over time.
What is chromosome comparison?
Chromosome comparison is where the DNA of one species is compared to another. For instance, Scientists compare the remains of prehistoric animals to current organisms roaming the Earth in our modern day world.

Why did DNA technology lead to more use if cladistics?
DNA technology allowed for the direct comparison of genetic material between organisms, providing a more precise and objective way to establish evolutionary relationships. This data could then be used in cladistics to construct more accurate phylogenetic trees and classification systems. Overall, the use of DNA technology in cladistics helped to improve the accuracy and reliability of evolutionary relationships among organisms.
What term literally mean comparison of shape or form and involves the comparison of the anatomy and development of organism?
morphologymorphology
How does the comparison of ape DNA and human DNA provide insights into the evolutionary relationship between the two species?
The comparison of ape DNA and human DNA reveals similarities that suggest a close evolutionary relationship between the two species. By analyzing the genetic similarities and differences, scientists can trace the evolutionary history and understand how humans and apes are related through a common ancestor.
