Properties of life include organization, expression/transmission of genetic information, energy use, maintenance of internal constancy, reproduction, growth & development, and evolution.
Organisms are not put together randomly, larger structures are made up of smaller structures that are made up of even smaller structures, forming a hierarchy: Atoms - > Molecules - > Cells - > Tissues - > Organs - > Organ Systems - > Multicellular organisms - > Population - > Community - > Ecosystems - > Biosphere.
Hypotheses remain open to tests, revisions and tentative acceptance or rejection, meaning they can be changed if new data is found that doesn’t support it.
Theory of Evolution: a broad, comprehensive explanation of a large body of information, supported by the accumulation of a wide range of different kinds of evidence, and subject to extensive experimental testing.
Organisms can be grouped by how they obtain energy, with producers/autotrophs being self-feeders that can sustain themselves without anything derived from other living beings, and consumers/heterotrophs being organisms that obtain organic food molecules by eating other organisms or substances derived from them.
DNA, or Deoxyribonucleic Acid, is the information molecule that instructs an organism to build itself and is the unit of inheritance that transmits information from parent to offspring, a form of reproduction.
Homeostasis is the ability to maintain internal consistency despite changes in external environments, allowing organisms to function properly and sense and react to stimuli if necessary.
Asexual reproduction produces offspring that is genetically identical to a single parent, but lacks genetic diversity, while sexual reproduction involves the mixing of genetic information from two parents into one or more offspring, resulting in new combinations of inherited traits and genetic diversity.
Emergent Properties are new, complex functions resulting from the interaction of parts, these properties “emerge” in a new level, meaning that they were not present in the level before.
