Evolution as a theory * Theory- in science‚ a well substantiated explanation of some aspect of the natural world Evolution- the accumulation of inherited genetic changes within populations over generations * Does not refer to changes that occur in an individual within its lifetime * Not limited to speciation that may only occur over long periods of time * Can occur over a few generations‚ and is most commonly expressed as an adaptation to a changing environment or the change in allele

Exam Review – January 2013 Diversity Unit - List taxonomic ranks in order. What is the significance of this order? Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ Species. Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example

(Ch. 12‚ Section “How Are Marine Organisms Classified?”) Plankton Plankton is a organism that float. Why is a copepod‚ which can swim and propel itself through the water‚ classified as plankton? (Ch. 12‚ Section “Plankton”) Because of its small size‚ it cannot swim very far or fast so its location

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

Introduction An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system.[2] These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.[3] As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚[4] they can be of any size but usually

Geology a science that examines the earth‚ its form and composition‚ and the changes it has undergone and is undergoing involves the knowledge of what happened before and the events occurring within the atmosphere requires not only a study of the materials found on earth but an understanding of the various geologic processes aims to develop an understanding of the earth’s materials and how these materials were changed and modified through the action of natural forces over a period of time Geology
