Population is a group of the same species living in the same place at the same time.
Community is a variety of populations occupying the same place.
Biosphere is the global ecosystem.
Ecosystem is the living and non-livingcomponents of an area.
Organization is the way the units of life function together, for example, groups of cells.
Energy is what all living things need to function, but the way they obtain energy is different.
Homeostasis is how a cell or organism maintains internal constancy, for example, if one’s body is too cold they will begin shivering to stay warm.
Reproduction, growth, and development are essential to life because that is how life multiplies.
Evolution is natural in life, whenever an organism is in an environment that is changing, the organism begins to adapt and naturally changes (evolves) to be suited for the environment.
Individual organisms are divided into two groups, single-celled and multicellular.
Emergent properties are characteristics that emerge at each level of organization, they are evidence of the levels of organization interacting to maintain life.
Primary producers obtain nutrients from the nonliving environment such as the sun.
A control group is the group used for comparison, for example a placebo for medicine rather than the actual medication.
Eukaryotic cells contain a nucleus while prokaryotic cells do not.
The three main branches of life are Domain Bacteria, Domain Eukarya, and Domain Archaea.
The scientific method steps are observe, ask questions, hypothesize and predict, collect data and make conclusions
Bacteria and Archaea are considered to be unicellular and prokaryotic.
Homeostasis is the maintenance of internal constancy, for example, if one is hungry they're stomach will growl
A standardized variable is one that remains constant throughout the experiment.
An experimental group is the group that may show different results, for example the actual medication.
A dependent variable is one affected by the experiment change, so more water caused the plant to grow.
Sexual reproduction produces genetically unique cells while asexual reproduction produces genetically identical cells.
Homeostasis also includes increasing the circulation of blood to the surface to allow the body to dissipate heat when one has a fever.
An independent variable is one changed in an experiment, for example, a certain amount of water added to a plant.
Consumers obtain nutrients from eating other organisms.
Decomposers obtain nutrients from dead organisms and organic waste.
Producer: Trees.
Primary consumers are herbivores; Deer
Secondary consumer: Humans.
Tertiary consumer: Lions.
Matter: anything that takes up mass
Element: a substance that cannot be chemically broken down
Cohesion: water molecules sticking together, high surface tension
Adhesion: water molecules forming hydrogen bonds with other molecules
Water dissolves hydrophilic molecules; salt
Water does not dissolve hydrophobic molecules; butter
Dehydration Synthesis: A reaction in which a larger molecule is formed from twomolecules by the removal of a water molecule; Monomer to Polymer
Hydrolysis: A reaction in which a large molecule is broken down into two molecules by the addition of water
