Cells
The most basic unit of life that all living things have in common.
What is a cell?
Blank is able to occur via evolution by natural selection on the population level.
What is Adaptation?
Blank refers to the physical expression of a genotype.
What is Phenotype?
Blank occurs when heritable variation leads to better fitness (reproductive success) and survival in the face of a stressor
What is Natural Selection?
A group/clade that excludes descendants of the same ancestor
What is paraphyletic?
Growth, reproduction, response, repair, homeostasis, adaptation, and metabolism.
What are the seven characteristics of life?
A variation so large it results in entirely different lineages
What is Macroevolution?
A trait that can only show if paired with the same allele (homozygous)
What is a recessive trait?
Accounts for the unity of all life on earth; Accounts for the diversity of all life on earth
What is descent with modification; what is Natural Selection?
The two types of prokaryotes
What are Archaea and Bacteria?
Exists within a population; Exists within a community
What are organisms; What are populations?
Speciation that occurs in the same geographical area
What is sympatric speciation?
A mutation that gives organisms extra sets of chromosomes (ex: 4n) and reproductively isolates those organisms, leading to speciation
What is polyploidy?
What is balancing selection; What is stabilizing selection?
The natural process by which life arises from non-living matter, occurred billions of years ago
What is Abiogenisis?
What is DNA?
A method of pre-zygotic reproductive isolation that involves a difference in mating season?
What is Temporal reproductive isolation?
Two alleles gives an individual a better chance of survival and reproduction than having two identical versions
What is Heterozygote advantage?
A selection graph that peaks on either end and dips in the middle.
What is Disruptive selection?
This molecule was the first to evolve because of its storage and transportation of genetic material, creation of ribosomes, and performance of chemical processes.
What is the RNA world hypothesis?
Varying number of chromosomes per species, represented by #n.
What is ploidy?
Who is LaMarck; Who is Darwin?
If two heterozygous parents have a child, what is the percentage that the child will show the recessive trait? What if they had a second child?
What is 25%?
Causes male to male competition for a female mate.
What is intrasexual selection?
The type of HGT that requires transmission of a virus between two prokaryotes
What is Transduction?
