Taxonomy
The area of the biological sciences devoted to the identification, naming, and classification of organisms in an ordered system is called taxonomy. Classification is made according to apparent common characteristics that indicate natural relationships. Taxonomy includes the science and laws or principles of classification.

Explain Why the taxonomy of protists is still changing?
The taxonomy of protists is always changing because they represent a diverse group of organisms that have complex evolutionary histories. New research techniques, such as molecular biology, continue to reveal previously unknown relationships among protist species, leading to reclassification and new groupings. Additionally, as more species are discovered and studied, taxonomists must update classifications to reflect our evolving understanding of their genetic, morphological, and ecological characteristics.
What are some protists household items?
Protists include algae and can be found in choc milk, coffee creamer,cottage cheese, frozen yogurt, pudding, sour cream whipping cream, hair conditioner,
brownie mix, relishes salad dressings, gravies, ice cream, margarine and facial creams.

What three kingdoms are in the three kingdom classification system?
The three kingdoms in the three kingdom classification system are Plantae (plants), Animalia (animals), and Fungi (fungi). Each kingdom represents a distinct group of organisms with specific characteristics and evolutionary relationships.
Advantages of the Three domain system:
- based on evolutionary relationships, which also show how kingdoms are related
- determines relationships with DNA sequencing and phylogenetics
- broadly classifies biodiversity into Eubacteria, Archaeabacteria and Eukarya allowing for kingdom changes
Advanatges of the Five kingdom system:
- classifies Eukaryotes correctly (Plantae, Fungi, Protista, Animalia, Monera)
- based on the three prinicipal means of nutition- photosynthesis, absorption and ingestion
- Seperates Kingdom Fungi, which previously had been part of the Kingdom Plantae
Disadvantages of Three domain system:
- classifies organisms too generally
Disadvantages of Five Kingdom system:
- No significant distinction between the bacteria types in Kingdom Monera (Eubacteria and Archaebacteria)
What is botanical name of a walnut plant?
Genus Juglans. There are many different species in this genus; you'd have to be more specific to identify which one you mean.
The English walnut tree is Juglans regia. Black walnuts comprise a lot of different species, but probably the most common in the US is Juglans nigra, the Eastern Black Walnut. The Small Black Walnut in Texas is Juglans microcarpa, and a species is native to California as well (Juglans californica).
What group is the lionfish in plankton nekton benthos?
The lionfish belongs in the nekton group. Nekton are aquatic organisms that are able to swim and move independently of water currents, unlike plankton which are drifters, and benthos which dwell at the bottom of a body of water.
What is the name of organisms that hunt for their own food?
Organisms that hunt for their own food are called predators. They actively seek out and consume other organisms as a source of energy and sustenance.
organelle → cell → tissue → organ → organ system → organism
What words make up the up the scientific name of an organism?
The scientific name of an organism consists of two parts: the genus name and the species name. The genus name is capitalized and the species name is lowercase. For example, in Homo sapiens (humans), "Homo" is the genus and "sapiens" is the species.
Why did evolutionary theory prove important in taxonomy?
Evolutionary theory provides a framework for understanding the relationships between organisms based on their shared ancestry and descent with modification. This has greatly influenced taxonomy by allowing classifications to reflect the evolutionary history of organisms, leading to more accurate and robust classification systems. By incorporating evolutionary principles, taxonomists can better organize and categorize species based on their evolutionary relationships.
What are the eight levels of classification from broadest to most specific?
Kingdom

es
Kingdom, Phylum, Class, Order, Family, Genus, Species.
Note there are sublevels, used occasionally by taxonomists, such as superorder, suborder, cohort, legion, alliance, tribe, subgenus epifamily and so on. The seven above are the seven universal divisions, used in microbiology, botany and zoology.

What is the scientific classification of tulip?
Kingdom: Plantae
Division: Angiosperms
Order: Liliales
Family: Liliaceae
Subfamily: Lilioideae
Genus: Tulipa
What is Saccharomyces boulardii?
Saccharomyces boulardii is a probiotic yeast which fights against pathogens in the body. S. boulardii is useful for diarrhoea, food poisoning, IBS, IBD, C. difficile, and Candida overgrowth.
It can be bought as capsule supplements and taken either on a daily basis (for conditions such as Inflammatory Bowel Disease) or as a one-off (for anyone with diarrhoea wanting a natural solution).
What is the scientific name for the cape seahorse?
The scientific name for the Cape seahorse is Hippocampus capensis.
What is the black lump remaining after burning sucrose?
The black lump is mostly carbon. Normally I would expect to find some partial combustion byproducts as well, since combustion is rarely 100% efficient.
What are the original five kingdoms?
The original five kingdoms are Monera (bacteria), Protista (protozoa and algae), Fungi (fungi), Plantae (plants), and Animalia (animals). This classification system has been revised over time, with the addition of new kingdoms and changes in classification.
What is the kingdom phylum class order family genus species of Milkweed?
Kingdom: Plantae
Phylum: Angiosperms
Class: Eudicots/Asterids
Order: Gentianales
Family: Asclepiadoideae
Genus: Asclepias
Species: Asclepias Syriaca
Why should you use an old culture for the endospore stain?
Spores are typically formed when an organism is enduring stressful conditions. If you wait until the culture is old then it is likely that some of the organisms will be experiencing stressful conditions such as lack of nutrients. It helps if you remember why the organism forms spores at all! The organism is protecting itself against harsh conditions, the spore will not germinate until conditions favour growth.
What are the common names of the safflower plant?
False saffron, dyer's saffron, American saffron, bastard saffron, Mexican saffron, and zaffer. In Chinese medicine, safflower flower is called hong hua; in India it is known as koosumbha.
What are the common names of the horehound plant?
White horehound, black horehound, houndsbane, marrubium, eye of the star, seed of Horus, marvel, bulls' blood, and houndsbane.
What are the common names of the gentian plant?
Bitter root, bitterwort, gall weed; G. macrophylla is known in China as qin jiao and G. scabra is known in Chinese as long dan cao.
