describe dna replication
the process of dna being copied.
what is an allele
a variation of a gene
who discovered evolution and natural selection
charles darwin
what is a gene pool
all genes present in a ṕopulation
what is carrying capacity
the maximum pop an environment can hold
which part of the cell cycle is dna replication
the S phase of interphase
what is the difference between genotype and phenotype
genotype is the allele combination, phenotype is the trait
what does a cladogram represent
it shows the relationships between different species and their common traits.
what are the 3 phases of cellular respiration
glycolysis, krebs cycle, electron transport chain
what are density dependent limiting factors
limiting factors that are dependent on high population (ex: competition, overcrowding, predators)
which enzymes are used to complete dna replication
helicase and dna polymerase
what does dominant allele and recessive allele mean
dominant allele is expressed in heterozygous (Aa) individuals, recessive allele is only expressed when both alleles are recessive (aa).
what is a pedigree chart
it shows a family tree and how traits are passed
what is the relationship between the cellular respiration and photosynthesis equations
they are opposites.
what is the name of organisms that make their own food
producer or autotroph
what is the difference between dna and rna nitrogen bases
dna has thymine, rna has uracil
when there are 2 heterozygous parents what is the chance the child will be recessive
25%
what is the difference between incomplete dominance and codominance
incomplete dominance is when the D and R alleles blend together, and codominance is when they both show up seperately.
where is the krebs cycle located
mitochondrial matrix
what percent of energy go to next trophic level
10%
what are the base pairs in dna
adenine-thymine, cytosine-guanine
which type of mutation causes sickle cell anemia
point missense mutation
give examples of evidence for evolution
fossil record, molecular similarities, anatomical similarities, embryology
where are the light independent reactions in photosynthesis
the stroma (fluid outside of thylakoid membranes)
decomposers produce this substance which is eaten organisms such as mites
detritus
