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)

F1 Generation correct answers The products of the Parental Generation

determinants for the same trait
Recessive Trait correct answers The trait temporarily becomes latent or hidden when paired with a
