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.
hypothesis must accomplish what two things
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.
Atoms join with other atoms to form molecules
are made up of protons, neutrons, and electrons

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
Origin of Life
Domain(3-Bacteria, Archaea, Eukarya)
Kingdom(4- Animal, Plant, Fungi, Protista)
Do Kings Play Cards On Fat Green Stools?
Genus then species
ex, Panthera pardus
What makes something qualify as living?
Organized into a cell/s
require energy inputs
Grow and develop
Respond to stimuli
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)
2 ways in which organisms can obtain their nutrients
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
Darwin’s “Survival of the Fittest”
Why study biology?
Treatment for malaria
breakdown organic wastes, releasing chemical components that can then be reused by plants and other primary producers
4 Eukarya Kingdoms
Animal- Consumers - multicellular
Plant- Producers- multicellular
Fungi- Decomposers - unicellular
Protista- producers, consumers, and decomposers - unicellular
