What is DNA replication?
The process where DNA is copied
Definition/Use of dominant allele
The allele that is expressed when different alleles are present
What country was Charles Darwin born in?
England
How do allele frequency's show up in gene pools? (2 answers)
decimal or percentage
what is the lowest level of of trophic levels?
The producers
What do 2 original DNA strands do?
Each original DNA strand separates
Definition/Use of recessive allele
Allele not expressed when DA is present
Definition of evolution
Process by which all organisms have changed over many generations
What is natural selection?
Change in the allele frequency or pops gene pool
What is the definition of emigration and what does it cause the population size to do?
The process where individuals move out of the population to elsewhere, causing the population size to decrease
What can we determine based on the DNA nucleotide sequence?
Determines the complimentary DNA strand
How many alleles do we inherit?
We inherit one allele from our mom and another from our dad
What are vestigial structures?
Structures that were inherited from ancestors that have lost most of their original size/function
What does the gene pool change in natural selection?
Change due to an environmental pressure
What affects the carrying capacity? (4 answers)
amount of space, food available, water available, and seasonal changes
What is the definition of DNA?
What do heterozygous contain?
1 dominant allele, 1 recessive allele
What do analogous structures not have in common with homologues structures?
Homologues structures have common ancestry while analogous structures do not
What is a gene pool?
A gene pool is when population members interbreed with one another
What level of the pyramid has the lowest energy percentage?
The quaternary consumers
What does helicase do to original DNA molecules?
They unzip the original DNA molecules by breaking hydrogen bonds
What does a gene do?
Wounds up and organizes chromosomes in x shapes
Why are bats and butterflies not considered related? (2 answers)
They dont have a common ancestor and develops from different embryonic tissues
How does evolution happen?
Evolution involves the change in allele frequency's in a population overtime
How quickly do organisms immigrate/emigrate depend on?
distance traveled, speed they move, and whether or not human activity moves around them
