Organisms to Ecosystems Exam 1 Flashcards
DNA transcribed to RNA that is translated to proteins
Central Dogma
The genetic makeup or set of alleles of an organism
Genotype
Describes the Manifestation of organisms
The observable physical traits of an organism which are determined by its genetic makeup
Phenotype
Organisms display an array of traits
Multiple phenotypes are found within a species. which compete. with one another for resources
Variation
Traits of offspring resemble those of their parents
Each phenotype is dependent at least partially on underlying genotype which is passed on to the offspring of individuals expressing that phenotype
Heritability
Which three features are needed for evolution to occur
Variation, heritability, differential fitness
Two or more atoms held together by covalent bonds
Molecules
Water
Any of several kinds of membrane-enclosed structures with specialized functions, suspended. in the cytosol of eukaryotic cells
Organelles
Life’s fundamental unit of structure and. function; the smallest unit of organization that can perform all activities required for life
barrier- separation of inside from the exterior
Cells
A specialized center of body function composed of several types of tissues all working together
organs
An integrated group of cells with a common structure function or both
only multicellular organisms have this
Cells communicating towards a goal
Tissue
An individual. living. thing consisting of one or more cells
organism
A group of individuals of the same species that live in the same area. and inter breed, producing fertile offspring
population
All the organisms that inhabit a particular area an assemblage of populations of different species living close enough together for potential interaction
Communities
All. the organisms in a given area as well as the abiotic factors with. which they interact; one or more communities and the physical environment around them
ecosystem
The entire portion of earth inhabited by life; the sum of all the planets ecosystems
