Order, reproduction, growth and development, energy processing, regulation, response to the environment, evolutionary adaptation.
Structure and function are correlated; function determines structure and structure determines function.
Experiment
A scientific test where usually conditions are controlled and there is one manipulated variable
What are the 3 domains of life?
Bacteria + Archaea- simple cells, old, consist of prekaryotics
Eukarya - Protists, Fungi, Plants, animals (multicellular of unicellular) more advanced/complx, consist of eukaryotic.
What are the subgroups of domain Eukarya?
Kingdom Protists, Fungi, Plantae, and Animalia
What are the levels of biological organization from the biosphere to molecules?
(Atoms - smallest unit of matter w/ elemental properties)
Molecules
Organelle
Cells
Tissue
Organ
Organ System
Organism
Population
Community
Ecosystem
Biosphere
Qualitive vs Quantitive Data
QUAL
usually in recorded description form
Comes from observations
QUAN
usually numerical measurements
Can be structured into tables + graphs
Analyzed w/ statistics
SIMILARITIES
Both can lead to new hypotheses, predictions, and experiments
Both are forms of data
What is the structure of a controlled experiment?
In a controlled experiment there are 2 groups. The purpose of them is so the scientist’s can see how much change their is between the two so they have something like a base their studies on.
FACTORS
Hypotheses
Independent Variable
Dependent Variable
Control Group
Experimental Group
What allowed the reclassification of the red panda by scientists?
The use of molecular evidence where DNA sequences were tested for evolutionary relationships between the red panda, bear, and raccoon family.
How are science and technology related?
They are connected because technology is used by scientists on their research or experiments, and science can lead to the creation of new tech.
Name the 5 unifying themes of biology.
Evolution is the Core theme of Biology
Life depends on the flow of information
Structure and function are related
Life depends on the transfer and transformation of energy and matter
Life depends on interactions within and between systems
Describe the process and products of natural selection.
PROCESS
Where the species more suitable to that environment will be able to reproduce, pass off traits to offspring, and live more than the species unsuitable for the environment. This cause the unsuitable species to die eventually.
PRODUCTS
Evolution
Adaptation
Biodiversity
How do nutrients flow within an ecosystem?
The sun is the inflow of light energy -> Producers (plants) -> Chemical energy in food -> Consumers (animals) -> Heat outflow
(Leaves take up CO2 from air; roots absorb H2O and minerals from soil.)
(Decomposers like work, fungi, and bacteria return chemicals to the soil)
