How is a protozoan parasite different from bacteria?
Protozoan parasites are single-celled eukaryotic organisms, while bacteria are prokaryotes. Protozoan parasites are generally larger and have more complex cellular structures compared to bacteria. Additionally, protozoan parasites often have more specialized modes of transmission and lifecycle strategies that are adapted to living within a host organism.
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.
What does hardy weinberge equilibrium mean?
Hardy-Weinberg equilibrium is a principle stating that allele frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences like mutation, natural selection, genetic drift, or gene flow. It serves as a null model against which population genetics data can be compared to detect evolutionary forces at work. Deviations from Hardy-Weinberg equilibrium can indicate that evolutionary processes are influencing the population.
What two things are compared when patterns of evolutionary relationships are constructed using molecular phylogenetics?
In molecular phylogenetics, patterns of evolutionary relationships are constructed by comparing genetic sequences, such as DNA or protein sequences, from different species. These sequences are analyzed to identify similarities and differences, which help infer how closely related the species are and the evolutionary pathways they have taken. The comparisons allow researchers to construct phylogenetic trees that illustrate the relationships and divergence among various organisms.
How does evolutionary biology unite ecoloy systematics ethology molecular biology population genetics and palentology?
The bottom line of all life is the DNA... Previously, we compared fossils and created evolutionary trees on the basis of structure and similarity. However, this can just be a co-incidence. Now we can compare molecular data, DNA and protein sequences and obtain the similarity and thereby predict, why our brothers in the evolutionary tree are different than us.

What happen when a marine water protozoan is kept in fresh water?
When a marine water protozoan is placed in fresh water, it experiences osmotic stress due to the difference in solute concentration. Freshwater has a lower concentration of solutes compared to the protozoan's internal environment, leading to water entering the cell through osmosis. This can cause the protozoan to swell and potentially burst, as they are not adapted to cope with such a drastic change in osmotic pressure. To survive, they would need to actively regulate their internal conditions or find a way to return to a saltier environment.
When is cladistics more useful the linnaen taxonomy?
Cladistics is more useful than Linnaean taxonomy when studying evolutionary relationships because it groups organisms based on shared evolutionary history. This allows for a more accurate representation of evolutionary relationships compared to Linnaean taxonomy, which is based on physical characteristics.

Compared to the early colonists in the Chesapeake those in colonial New England had?
many more deaths due to malaria
What is Cladistics definition?
Cladistics is a method of biological classification based on the concept of common ancestry, where organisms are grouped together based on shared derived characteristics (synapomorphies) that reflect their evolutionary relationships. This approach emphasizes the branching patterns of evolution, creating a cladogram that illustrates the evolutionary lineage and divergence of species. Cladistics aims to provide a more accurate representation of evolutionary history compared to traditional classification methods.
What was art in the Philippines like during pre-colonial period?
Art in the Philippines during pre-colonial period was limited. It was done using the crude tools and methods. The kind of art done was conservative too as compared to what is done today.
Compared with the seventeenth century American colonial society in the eighteenth century showed?
c. greater gaps in wealth and status between rich and poor
Biological classification system based on phylogeny?
Phylogenetic classification is a biological system that categorizes organisms based on their evolutionary relationships derived from shared ancestry. It organizes species into hierarchical groups that reflect their genetic and evolutionary connections, helping scientists understand how organisms are related and evolved over time. This system aims to provide a more accurate representation of the evolutionary history of life on Earth compared to traditional classification systems.

Deviations from Hardy-Weinberg equilibrium can indicate that evolutionary processes are influencing the population.
What is difference between Linnaeus classification and phylogenetic classification?
Linnaeus classification is based on physical and observable characteristics of organisms, categorizing them into hierarchical groups like kingdoms and species. Phylogenetic classification, on the other hand, is based on evolutionary relationships and genetic similarities among organisms, organizing them into groups that reflect their evolutionary history. Phylogenetic classification provides a more accurate depiction of the evolutionary relatedness between different species compared to Linnaeus classification.
