Taxonomy
This taxonomic ranking is the second largest, and includes 6 categories, animalia, plantae, fungi, monera, protista, and eubacteria
What is kingdom?
This is the thing in an experiment that the scientist changes/tests
What is an independent variable?
This characteristic shared by all living things is a tiny life form, considered to be the basic unit of life.
What are cells?
This cell classification is used to describe any cell that contains a nucleus.
What is a Eukaryote?
True or False: There are more bacterial cells in the human body than there are human cells
True!
This taxonomic ranking is the largest, and includes only 3 categories, "Eukarya, Archaea, and Bacteria"
What is domain?
This is the thing in an experiment that the scientist measures in order to determine the effects of the thing they are testing.
What is the dependent variable?
What is reproduction?
This cell classification is used to describe a cell that does not contain a nucleus
What is a prokaryote?
True or False: Koalas contain finger prints so similar to humans that they have been mistaken for human prints at crime scenes
True!
The 3rd largest taxonomy category, having to do with the structure and organization of the living thing
What is phylum?
These are all of the things in an experiment that are kept the same across all trials.
What are control variables?
This characteristic of living things is predictable change over time.
What is growth and development?
This is a type of cell that contains a cell wall and can do photosynthesis because it contains chlorophyll
What is a plant cell?
This animal contains exactly zero bones in its body, because its structure is made entirely out of cartilage.
a. sharks
b. humans
c. bats
d. spider monkeys
a. sharks
This is the most specific taxonomic ranking, which describes exactly one type of living thing.
What is species?
This is the gold-standard of scientific research. It is a kind of experiment with at least two trials in which researchers only change one thing, so that they can compare the results with and without that change.
What is a controlled experiment?
This characteristic of life is a result of changes in DNA which result in changes in a population over a long time.
What is adaptation and evolution?
This is a type of cell that contains a cell wall made of chitin, and does not contain chlorophyl
What is a fungal cell?
This unique animal contains three hearts and blue blood.
a. Platypus
b. Octopus
c. Snail
d. Sloth
What is an octopus?
What is a group of living things that share common genetics and traits?
What is a family?
These are the 7 steps of the scientific method
What are ask a question, form a hypothesis, design an experiment, test the hypothesis/gather data, analyze data, form a conclusion, and share the results
This characteristic of living things is the ability to maintain a stable internal environment
What is homeostasis?
These are single-celled organisms which contain a nucleus that do not fit into the categories of animals, land plants, or fungi
What are protists?
This is the number of cells in an average human body.
a. 10-15 quadrillion
b. 150 - 160 million
c. 8-9 billion
d. 36 - 37 trillion
what is 36-37 trillion (roughly 185x the number of stars in the milky way!)
