Vocab Quiz Set 4 Flashcards
Any of several molecular mechanisms in which ions or molecules are transported across a cellular membrane requiring the use of an energy source (e.g., glucose, sodium [Na+], calcium [Ca+], and potassium [K+]).
Pumps
A proposed explanation in evolutionary biology stating that species are generally stable over long periods of time. Occasionally there are rapid changes that affect some species which can quickly result in a new species.
Punctuated equilibrium
A pattern of inheritance in which the phenotypic effect of one allele is only expressed within a homozygous genotype. In a heterozygous condition with a dominant allele, it is not expressed in the phenotype.
Recessive inheritance
A cellular structure composed of RNA and proteins that is the site of protein synthesis in eukaryotic and prokaryotic cells.
Ribosome
A body of evidence based knowledge gained through observation and experimentation related to the natural world and technology.
Science
The process of breeding organisms that results on offspring with desired genetic traits.
Selective breeding
The process in which the DNA molecule uncoils and separates into two strands. Each original strand becomes a template on which a new strand is constructed, resulting in two DNA molecules identical to the original DNA molecule.
Semiconservative replication
A trait, associated with a gene that is carried by either the male or female parent (e.g., color blindness and sickle cell anemia).
Sex-linked trait
A process typically caused by the genetic isolation from a main population resulting in a new genetically distinct species.
Speciation
The process in which amino acids are arranged in a linear sequence through the processes of transcription of DNA and to RNA and the translation of RNA to a polypeptide chain.
Protein synthesis
The lowest taxonomic level of biological classification consisting of organisms capable of reproduction that results in fertile offspring.
Species
The measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval.
Specific heat
A series of predictable and orderly changes within an ecosystem over time.
Succession
A relationship between two organisms (i.e., mutualism, in which both organisms benefit; parasitism, in which one organism benefits and the other organism is harmed; and commensalism, in which one organism benefits and the other organism does not benefit or is not harmed).
Symbiotic relationship
A set of interacting or interdependent components, real or abstract, that form an integrated whole. An open system is able to interact with its environment. A closed system is isolated from its environment.
System
