GRADED A+ Q & A 2023 ATESTED
Organism correct answers A living entity made up of one or more cells
Theory correct answers An explanation for a very general class of phenomena or observations
Cell Theory correct answers All organisms are made of cells and all cells come from preexisting cells
Null Hypothesis correct answers Specifies what we should observe when the hypothesis being tested
isn't correct
Control Group correct answers A group that checks for other factors which are not being tested
Two components of scientific theories correct answers Pattern and process
Population correct answers Individuals of the same species that are living in the same area at the same
time
Descent with modification correct answers Evolution
Pattern component of Evolution correct answers 1) Species change through time
2) Species are related through common ancestry
Fossil Record correct answers All fossils that have been found and described in the scientific literature
Extant Species correct answers Living species
Extinct Species correct answers No longer existing species
Transitional Feature correct answers A trait in a fossil species that is intermediate between those of
older and younger species
Vestigial Trait correct answers A reduced or incompletely developed structure that has no function or
reduced function but is clearly similar to functioning organs or structures in closely related species
Phylogeny correct answers A family tree of populations or species
Homology correct answers Similarity that exists in species because they both inherited the trait from a
common ancestor
Genetic Homology correct answers Similarity having to do with similar DNA structuring
Developmental Homology correct answers Similarity in the embryonic stage
Structural Homology correct answers Similarity in adult morphology (form)
, Darwin's Four Postulates correct answers 1) Individuals vary in the traits they posses
2) Some trait differences are heritable
3) More offspring are produced than can possibly survive in one generation
4) The individuals who survive best and produce the most offspring is not a random subset of the
population
Theory of Evolution by Natural Selection (in two parts) correct answers 1) Heritable variation leads to...
2) Differential reproductive success
Biological Fitness correct answers The ability of an individual to produce surviving offspring, relative to
that ability in other individuals in the population
Adaptation correct answers A trait that increases the fitness of an individual in a particular environment
Speciation correct answers A population of one species splits into two different species because of
natural selection
Tree of Life correct answers A family tree or organisms
Genetics correct answers The branch of biology that focuses on the inheritance of traits
Heredity correct answers Transmission of traits from parent to offspring
Trait correct answers Any characteristic of an individual
Model Organism correct answers A species that is used for research because it is practical and because
conclusions drawn from studying it turn out to apply to many other species as well
Phenotype correct answers The distinct physical display of the genetic makeup of an organism
Pure Line correct answers Consists of individuals that produce offspring identical to themselves when
they are self-pollinated or crossed to another member of the pure-line population
Hybrids correct answers Offspring from matings between true-breeding parents that differ in one or
more traits
Parental Generation correct answers The first cross between two individuals
F1 Generation correct answers The products of the Parental Generation
Monohybrid Cross correct answers Mating between parents that carry two different genetic
determinants for the same trait
Recessive Trait correct answers The trait temporarily becomes latent or hidden when paired with a
different version of the same trait
