-Primitive cells on early Earth that performed anaerobic processes and lived in hot places. -Divide of bacteria and archaea (anaerobic processes) -Eukaryotes were formed (aerobic processes) -Multicellular organisms (aerobic respiration)
What is four steps of the evolution of cells?
100
-a variant form of a gene. -A unit of heredity that contributes to the characteristics or traits of an organism. -the physical location of a gene. -A discrete unit of genetic material composed of DNA and associated proteins.
What is allele, gene, locus and chromosome?
200
1. A boundary, such as a membrane, separated the internal contents of the inner structures from the external environment. 2. Polymers contain information 3. Polymers have enzymatic functions 4. They eventually developed the capability of self-replication.
What is a protobiont?
200
-one trait in a pair of alleles masks the other and is shown in the individual. -The phenomenon in which a single individual expresses two alleles. ex. AB blood type -The phenomenon in which a heterozygote that carries two different alleles exhibits a phenotype that is an intermediate between two homozygous parents ex. pink flower from a red flower and a white flower.
What is dominance, codominance, and incomplete dominance?
300
-deep sea vent hypothesis -early atmosphere hypothesis -extraterrestrial hypothesis
What is how organic molecules formed?
300
-The process that eliminates those individuals that are less likely to survive and reproduce in a particular environment, while allowing other individuals with traits that confer greater reproductive success to increase in numbers. -The process and structure by which organisms adjust to changes in their environment.
What is natural selection and adaptation?
400
-transitional species-an organism that provides a link between earlier and later forms. -vestigial structures-An anatomical feature that has no apparent function but resembles a structure of a presumed ancestor. -homology-A fundamental similarity that occurs due to descent from a common ancestor. -biogeography-The study of the geographic distribution of extinct and modern species. -convergent evolution-The process whereby two different species from different lineages show similar characteristics because they occupy similar environments. -fossil record
What is the evidence of evolution?
400
states that two copies of a gene segregate from each other during gamete formation and during transmission from parent to offspring.
What is Law of Segregation?
500
-changes in a population's gene pool from generation to generation. -changes that creat new species and groups of species.
What is microevolution and macroevolution?
500
States that the alleles of different genes assort independently of each other during gamete formation.
What is Law of Independent Assortment?
