Convergent evolution - Study guides, Class notes & Summaries

GMO (genetically modified organism) - An organism whose DNA has been deliberately altered. Made possible by Recombinant DNA technology. Evolution - Change in a population or species over generations Microevolution - Change in allele frequencies in a population over generations. Macroevolution - Evolution at or above the species level Charles Darwin - Father of evolution Darwin's Theory of Evolution - Species living today descended from a single ancestral species. Two main components are ...

In which of the following examples would sepeciation most likely occur? A) Two populations of oak trees begin releasing pollen at different times of the year, one in the spring and the other in the fall B) Unseasonably warm temperatures cause an unusual low pressure zone over the Caribbean leading to a hurricane that eradicates a population of parrots on the island of Saba C) The Fukushima nuclear power plant fails and leaks radioactive water into the ocean causing sterility among an entire p...

2 types of lateral meristems: - Cork cambium vascular cambium 2 ways to increase allele diversity/allele frequency distribution: - 1.) gene flow 2.) mutation 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogenetic Adventitious Root Systems - Roots that emerge from the stem just above ground to help support plants in shallow soils Allopatric Speciation - Separated by some physical barrier Annuals - Angiosperm plants that die off at the end of each yea...

Another term for evolution by Darwin - Answer-descent with modification Are habitat isolations physical barriers? - Answer-No just different habitats not an actual physical fence or anything Convergent evolution - Answer-evolution of analogous (similar) features in related groups convergent evolution tells us about ancestry. t/f? - Answer-False it does not it only tells us the evolution of similar features Dependent selection favors which phenotype? - Answer-The less common in a population...

Give an example each of heritable and non-heritable variation Eye-color and hobbies What is the difference between somatic and germ cells? Somatic cells are the majority of the cells in the body, germ cells can give rise to gametes Can somatic mutations be passed on to the next generation? No only germ line mutations can Are most mutations dangerous to the survival of the individual in which they occur? No, most mutations appear to be neutral Why is the evolutionary tree of life ...

MCAT Biology Exam Latest Updated 2024 With Complete Solutions Natural selection (types) Different types of selection lead to changes in phenotype: 1) Stabilizing selection 2) Directional selection 3) Disruptive selection 4) Adaptive selection Stabilizing selection Keeps the phenotypes in a narrow range, excluding extremes. Directional selection Moves the average phenotype toward one extreme. Disruptive selection Moves toward two different phenotypes at the extremes and can lead to sp...

Power equation= P=fv f=force v=velocity Which of the following is LEAST likely to occur in a muscle fiber that is metabolizing anaerobically? A.Fermentation of glucose to lactic acid B.Phosphorylation of ADP within the electron transport chain C.Depletion of stores of glycogen D.Acidification of the cytoplasm B fast-twitch muscle Muscle fibers that contract rapidly and powerfully, with little endurance. They have few mitochondria and large glycogen reserves. They depen...

Natural Selection - Answer A theory in which individuals with certain traits produce more offspring than others without these traits. Evolution - Answer The gradual change in a species over time. Adaptation - Answer When the heritable trait increases an individuals fitness in a particular environment. Ancestral trait - Answer Is a character that existed in an ancestor. Derived trait - Answer Is one that is a modified form of the ancestral trait, found in a descendants....
