---|---|---|---|---|---|
Biosphere | show 🗑
|
||||
show | Consists of all the organisms living in a particular area, as well as the nonliving, physical components of the environment with which the organisms interact, such as air soil, water, and sunlight.
🗑
|
||||
Community | show 🗑
|
||||
show | An interacting group of individuals of one species.
🗑
|
||||
show | An individual living thing.
🗑
|
||||
show | Consists of several organs that work together in performing a specific function. Examples: culatory system, digestive system, nervous system.
🗑
|
||||
show | For example: brain, heart, liver, nerves.
🗑
|
||||
show | Each has a specific function and is made up of similar cells.
🗑
|
||||
Cell | show 🗑
|
||||
Organelle | show 🗑
|
||||
Molecule | show 🗑
|
||||
show | Smallest particle of ordinary matter.
🗑
|
||||
show | Plants and other photosynthetic organisms are the producers that provide food for a typical ecosystem.
🗑
|
||||
Consumers | show 🗑
|
||||
Decomposers | show 🗑
|
||||
show | The properties of life that arise from the structural level of a cell illustrate another important theme of biology. The saying "the whole is greater than the sum of its parts" sums up this idea.
🗑
|
||||
Evolution | show 🗑
|
||||
Prokaryote | show 🗑
|
||||
Eukaryote | show 🗑
|
||||
show | The foundation for the unity of life is the genetic information in DNA molecules. Each DNA molecule is up of two long chains coiled together into what is called a double-helix. Four chemical building blocks of DNA: A,T,C, and G.
🗑
|
||||
Taxonomy | show 🗑
|
||||
Kingdoms | show 🗑
|
||||
show | Scientists agree the kingdoms of life can be organized into three overarching groups.
🗑
|
||||
show | Consists of prokaryotes, organisms with prokaryotic cells. Most prokaryotes are unicellular and microscopic.
🗑
|
||||
show | Domain that has prokaryotes, but is not Domain Bacteria.
🗑
|
||||
show | Eukaryotes, organisms with eukaryotic cells, are now grouped into the various kingdoms of domain Eukarya. Eukaryotic cells have a nucleus and other internal structures called organelles.
🗑
|
||||
show | A diverse collection of of mostly single-celled organisms. Some make food using photosynthesis. Others (known as protozoans) eat other organisms, such as algae and prokaryotes.
🗑
|
||||
show | A diverse group that inludes molds, yeasts, and mushrooms. They are mostly decomposers. They break down the remains of dead organisms and organic wastes, such as leaf litter and animal feces, and then absorb the nutrients into their cells.
🗑
|
||||
Kindgon Animalia | show 🗑
|
||||
show | Produce their own food by photosynthesis and have cells with rigid walls made of cellulose.
🗑
|
||||
show | 1.) Population with varied inherited traits. 2.)Elimination of individuals with certain traits.
3.) Reproduction of survivors.
🗑
|
||||
show | Mostly about *describing* nature. Verifiable observations and measurements are the data of discovery science. Leads to conclusions based on a type of logic called inductive reasoning. Reasoning derives general principles from a big # of spec. observ's.
🗑
|
||||
show | Mostly about *explaining* nature. Involves proposing and testing hypotheses. Logic used is deductive reasoning. (if all organisms are made of cells, and humans are organisms, then humans are made of cells.)
🗑
|
||||
Controlled Experiment | show 🗑
|
||||
show | The variable that is given to the experimental group.
🗑
|
||||
Dependent Variable | show 🗑
|
||||
show | any alteration in the structure or function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment.
a form or structure modified to fit a habitat.
🗑
|
||||
show | An act or instance of viewing or noting a fact or occurrence for some scientific or other special purpose
🗑
|
||||
show | systematic knowledge of the physical or material world gained through observation and experimentation.
🗑
|
||||
show | An educated guess based off of previous observations. Must be testable and follow the if..., then... format.
🗑
|
||||
show | The group in a controlled experiment that does *not* receive the independent variable.
🗑
|
||||
Inference | show 🗑
|
||||
Experimental Group | show 🗑
