What characteristic allowed scientists to definitively classify the sea anemone as an animal rather than a plant?
The ability of sea anemones to move freely, capture and consume food, and react to their environment are characteristics that helped scientists definitively classify them as animals rather than plants. Additionally, sea anemones lack the cell walls, chloroplasts, and ability to photosynthesize that are characteristic of plants.
How do scientist classify human beings?
All living Humans are one subspecies of one species, Homo Sapiens. Race is not regarded as a biological concept, but rather a cultural one. Human genes are remarkably uniform in populations all over the globe. Scientists classify all living things by examining their cell structure. Humans are classified as eukariotic.

Did the theory of evolution change the way that biologists thought about classification?
Yes, it most certainly did. Since common descent became fact, biologists mostly classify organisms not by their place in the nested hierarchies, but by their descent. Although, interestingly, it was the first attempts to systematically classify life, by Carl Linnaeus, that provided the key insights leading eventually to the thesis of common descent, as formulated by Charles Darwin.
Did controlled experiments or multiple observations lead to the generalization that all organisms are composed of cells?
The generalization that all organisms are composed of cells was primarily supported by multiple observations rather than controlled experiments. Early scientists like Robert Hooke and Anton van Leeuwenhoek made observations using microscopes and discovered cells in living organisms, which laid the foundation for the cell theory. Subsequent research through various observations across different organisms further confirmed this generalization.
Why do scientists classify a sponge as a simple animal and not a plant?
Scientists classify sponges as simple animals because they are multicellular organisms that lack tissues and organs found in more complex animals. Sponges also feed by filtering particles from water, which is a characteristic of animals rather than plants.

What was not a consideration for Carolus Linnaeus when he developed his system of nomenclature of organisms?
Carolus Linnaeus created the scientific classification system for living things. He did not consider whether the system would allow scientists to classify living things by their evolutionary relationships.
How do aboringinal people classify organisms?
Aboriginal people classify organisms based on traditional knowledge, often categorizing them according to their relationship with the natural world and the cultural significance they hold. This classification system may involve groupings based on ecological role, behavior, appearance, or spiritual importance rather than taxonomy.

What is a dichotomous key and why is it important?
A dichotomous key is a tool used to identify and classify organisms based on their characteristics through a series of choices with two alternatives at each step. It is important because it provides a systematic way to determine the identity of an organism, helping researchers, scientists, and even amateurs to accurately classify and study different species.

What is artificial system of classification?
An artificial system of classification is a method of categorizing organisms based on a few selected characteristics rather than their evolutionary relationships. It groups organisms together based on practical features rather than their natural relationships. This system is subjective and can lead to misleading classifications.
What is the phenetics approach to classification?
Phenetics is an approach to classification based on overall similarity, without emphasizing evolutionary relationships. It relies on observable characteristics, such as morphology or behavior, to group organisms. Phenetics aims to classify organisms based on their overall similarities rather than on shared evolutionary history.
How can DNA help scientists make the classification of similar organisms such as giant pandas and red pandas more accurate?
It revealed that the panda is a bear rather than related to the raccoon.
Are dichotomous keys based on a phylogenetic or morphological approach to classification?
Dichotomous keys are typically based on a morphological approach to classification, using observable physical characteristics to identify and classify organisms. This method involves sorting organisms into groups based on shared physical traits rather than evolutionary relationships.
Is brittle star a producer?
No, they are carnivorous and mostly eat dead matter. If anything I'd classify then as detrivores (decomposers) rather than producers.
