The passing on of characteristics from parents to offspring

Characteristics that are inherited

The branch of biology that studies heredity

male and female sex cells

transfer of pollen grains from a male reproductive organ to a female reproductive organ

A fertilized egg cell

offspring of parents that have different forms of the trait

observed trait when both are present

every individual has two alleles of each gene and when gametes are produced, each gamete receives one of these alleles

the way an organism looks or behaves

The allele combination an organism contains

An organism is ______ for a trait if its two alleles for the trait are the same

An organism is ______ for a trait if its two alleles for the trait differ from each other

different traits are inherited independently of each other

every individual has two alleles of each gene and when gametes are produced, each gamete receives one of these alleles

composed of nucleic acids enclosed in a protein coat and are smaller than the smallest bacteria

a cell in which a virus replicates

a virus that infects a bacterium

outer protein coat of a virus

process in which viruses infect living cells, alter their DNA to make new viruses and then destroy the host cell

process where viral DNA is integrated into the host cell's chromosome which allows for the viral DNA to be replicated

viral DNA that is integrated into the host cell's chromosome is called a _____

RNA virus that converts its RNA into DNA once inside the host cell

enzyme a retrovirus carries inside its capsid

composed of proteins but have no nucleic acid to carry genetic information; behave like viruses

composed of a single circular strand of RNA with no protein coat; cause infectious diseases in plants

process in which autotrophs break down and release the energy of inorganic compounds containing sulfur and nitrogen

the asexual process by which bacteria reproduce by transferring all or part of its chromosome through a pilus to another bacteria

bacteria that require oxygen for respiration

bacteria that are killed by oxygen

formed when bacteria face unfavorable environmental conditions to protect a bacterium's DNA

powerful and deadly poison produced by some bacteria

a process where some bacteria can convert N₂ in the atmosphere into ammonia

asexual process in which a bacterium reproduces by copying its chromosome before splitting

The grouping of objects or information based on similarities

the branch of biology that groups and names organisms based on studies of their different characteristics

two-word naming system

a group of similar species

the second word in binomial nomenclature which sometimes describes a characteristic of the organism

a group of similar genera

a taxon of similar families

a taxon of similar orders

a taxon of similar classes
