species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete, post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write a 1-page lab report using the following scientific method sections: • Purpose • What would happen if a species within a population were to suddenly split in two groups by an earthquake

~20 hours a week, experience with teaching, biology (specifically marine) and manual labor are all recommended. Research emphasis include: 1. how organisms are exposed to metals 2. how these metals cause toxicity 3. investigating concentration, speciation, and isotopic compositioni of contaminant metals 4. study of host-pathogen interactions 5. ecology & evolution of pathogenic microorganisms 6. adaptation of pathogenic and

Raptors-Birds of prey Raptors are known as birds of prey. They hunt and feed on other animals. The term "raptor" is derived from the Latin word rapere (meaning to seize or take by force). These birds are characterized by keen vision that allows them to detect prey during flight and powerful talons and beaks. Many species of birds may be considered partly or exclusively predatory. However, in ornithology, the term "bird of prey" applies only to birds of the families listed below. Taken literally

shrubs. Their stings are often incapable of penetrating human skin, so the hive and swarms can be handled with minimal protection. They occur largely sympatrically though they are very distinct evolutionarily and are probably the result of allopatric speciation, their distribution later converging. Given that A. florea is more widely distributed and A. andreniformis is considerably more aggressive, honey is – if at all – usually harvested from the former only. They are the most ancient extant lineage of

that seems to continuously baffle scientists is the Drosophilia fly. This Drosophilia has been said to have branched from one species of fly into over 800 native,diverse species seen in Hawaii alone. These species are said to still be undergoing speciation due to genetic mutations and adaptations that result upon reproduction. A major player in the results of this diversity has been a result of adaptive radiation. Adaptive radiation is defined as a time of

selection 8. Macroevolution is long-term evolution that can cause extinction or specialization/development in a species. Microevolution is short-term evolution that primarily impact small-scale changes like change in phenotypic ratios. 9. Speciation is when a new species can arise when members of a population become isolated for a long period of time. Geographic isolation is when species are separated from exchanging genes with other organisms of the same species and start to specialize within

known that these cataclysms were random occurrences and not caused by the actions of any one single species. The extinction of species is not normally considered an important element of Neodarwinian theory, in contrast to the opposite phenomenon, speciation. In the wake of mass extinction periods, the fossil records provide an accurate and reliable source of information invaluable to the study of evolution. Today, there is evidence mounting to suggest that the sixth mass extinction may be beginning-

Review for BSC1010 Final that will consist of 50 questions taken from these facts. 1. A modified form of cellulose found in the exoskeletons of insects and crustaceans is known as chitin. 2. Non-polarity and insolubility characterize biological compounds known as lipids. 3. Alpha helix and beta pleated sheets are examples of the secondary level of protein structure. 4. Components of nucleic acids include a five-carbon sugar, a phosphate group, an organic nitrogen containing base, and phosphodiester

causing polymorphisms. Thus they compared the sequence to check for any known mutation and its severity. 3. What is the difference between paralogs and orthologs? (100 words) a) Orthologs are homologs of a particular gene resulting due to a speciation event and paralogs are a result of gene duplication event. Orthologs generally have similar functional nature unlike the paralogs. Orthologus homology is between different species and paralogs are for the same species. 4. Assume that a new disease
