a proposed explanation for observed phenomena; Based on observations.

is an explanatory hypothesis for natural phenomena that is exceptionally well supported by the empirical data. A theory can be thought of as a hypothesis that has withstood the test of time and is unlikely to be altered by any new evidence.

• 1.It must clearly establish mutually exclusive alternative explanations for a phenomenon.
• 2.It must generate testable predictions.

some measurable entity that is available at the start of a process and whose value can be changed as required

created by the process being observed and whose value cannot be controlled.

hypothesis has not been disproven over time and has a large body of data to support it.

• do not include a sufficiently large and representative set of observations of the world
• data are more reliable than anecdotes
• in which, based on just one or a few observations, people conclude that there is or is not a link between two things.

• make up both living and non-living things.

AMC TOBO PC EB

is multi-cellular individual.

is a group of individuals of the same kind of organism living in an area.

consist of all populations of all species in a specified area

a community interacting with its physical and chemical environment

all regions of Earth’s crust, waters, and atmosphere in which organisms live

• Domain(3-Bacteria, Archaea, Eukarya)
• Kingdom(4- Animal, Plant, Fungi, Protista)
• Phylum(ex. chordata)
• Class(ex. mammalia)
• Order(ex Carnivora)
• Family(ex. felidea)
• Genus(ex. panthera)
• Species(ex. pardus)

Do Kings Play Cards On Fat Green Stools?

• Genus then species
• ex, Panthera pardus

• Organized into a cell/s
• Contains DNA
• Can reproduce
• require energy inputs
• Grow and develop
• Respond to stimuli
• Homeostatic
• Evolves

acquires energy and raw materials from the environment (ex photosynthesis)

to convert solar energy to chemical energy. (use sunlight to make sugars). (plants, bacteria etc)

producers and cosumers

• energy and nutrients are obtained by consuming producers and other organisms.
• Ex: animals decomposers

• is not cyclic
• from sunlight to producers to consumers

• Biological instructions are encoded in a molecule known as DNA
• accounts for an individuals traits

is the mechanism by which parents transmit DNA to offspring

• Mutations: adaptive traits

• Technology
• Health
• Global Patterns

Treatment for malaria

breakdown organic wastes, releasing chemical components that can then be reused by plants and other primary producers

• Bacteria
• Archaea
• Eukarya

• Animal- Consumers - multicellular
• Plant- Producers- multicellular
• Fungi- Decomposers - unicellular
• Protista- producers, consumers, and decomposers - unicellular
