What is the binomial nomenclature? Why is it important to science? Latin naming system for all living things 8. Name the three domains and characteristics of each. Bacteria, archaea, eukaryote 9.
Alignment Vibrio cholerae MS6 DNA, complete genome, chromosome 1 [pic] [pic] 78b. How many base pairs long is the alignment? 2936971 base pairs 7c. In which organism is this similar sequence found? Is there any variation in different strains of this species?
The Evolution of Populations Study Guide A Answer Key Section 1. Genetic Variation Within Populations 1. B 2. d 3. gene pool 4. combinations of alleles 5. allele frequencies 6. ratio or percentage 7. mutation 8. recombination 9. hybridization 10. gene pool 11. allele frequency Be Creative: Logos may vary but should illustrate the importance of genetic diversity. Section 2. Natural Selection in Populations 1.
Cladistic : an approach to systematic in which organisms are placed into groups called clades based primarily on common descent. 9. Cladogram : a diagram used in cladistics which shows relations among organisms. 10. Classes : In Linnaean classification, the taxonomic category above the level of order 11.
A few of those examples includes: Humans, findings of fossil records, record finding of changes in existing species, and biochemical and anatomical similarities. 2. Humans shape their environment in ways that other organisms cannot. Are humans subject to the same pressures of natural selection as other organisms? Why?
Unit 4 development through the Life stages. P2 Explain the potential effects of five different life factors on the development of an individual. In this assignment I am going to explain the potential effects of five different life factors on the development of an individual. There are five life factors that can effect a person’s growth and development, these are: • Genetic • Biological • Environmental • Socioeconomic • Lifestyle The effect of growth and development can affect an individual in physical intellectual language emotional and social development. Every chromosome carries units of inheritance this is known as genes.
108) And from the study of the few remaining pre- historic cultures, to identify the similarities and differences between human behaviour over a period of time. The study of genetics in particular DNA, provides evidence of the transmission of genes through generational and of any genetic mutations and there time scale. There is both cultural and historical evidence relating to natural and sexual selection covering strategies over a choice of mate & skills in raising & motivating offspring, Family size, the structure of extended family, and longevity. Data from the past can be deprived from pre-historic art and tool making and from skeletons depicting body size, brain size and prominent characteristics. The study of similarities and differences of
3. In biogeography studies, similar animals that seem to be closely related are adapted to different environments in nearby areas. Also, in areas that are widely separated animals that seem to be unrelated are observed to have similar adaptations to similar environments in the separate areas. 4. Fossils show that a group of organisms, such as marine mammals, have changed over time to adapt to different environments.
Did the phylogenies of the different islands support the theory of one colonization followed by adaptive radiation and convergent evolution? Yes | 1. How did one species produce so many different species (the six ecomorphs)? The need to survive in different areas. | 1.
How do bacteria reproduce? by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). 6.
