CH 17 BIOLOGY VOCABULARY AND ASSESSMENT CH 17 SEC 1 1. Binomial nomenclature: Linnaeus’s system of naming organisms‚ giving a scientific two-word name to each species- the first part being the genus‚ and the second the species 2. Class: taxonomic group that contains one or more related orders 3. Classification: grouping of organisms or objects based on a set of criteria that helps organize‚ communicate‚ and retain information 4. Division: taxonomic term used instead of phylum to group related

intact. A rainforest is the perfect example of how we currently keep this environment friendlier and healthier. Ethics‚ the study of ecology‚ economics‚ and aesthetics can explain why we conserve biodiversity. As we begin to kill species‚ we have to remember that each species has a right to life. We also have to take into consideration that we are being selfish when we kill off rainforest and not allow our future generations see what nature has for them. On the ecological side‚ reducing the rainforest

Human and Nature As a biological species‚ human beings are indeed part of the nature and life activity of human body shall consistently follow the natural law. During the long-term evolution of the nature‚ human beings have developed the brainpower‚ which has surpassed other species and built up extremely complicated and rigorous social organization system. Although human beings have so many unique features‚ especially high initiative and creative ability‚ compared

Wildlife conservation is the practice of protecting endangered plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife andwilderness lands to humans.[1] Many nations have government agencies dedicated to wildlife conservation‚ which help to implement policies designed to protect wildlife. Numerous independent nonprofit organizations also promote various

As seen on picture 1.1 three species of finch have evolved on different islands and environment‚ which than have lead to the diversity of three finches over each island. Each finches through

University Biological Station. This was done by setting up multiple transect lines in both locations‚ all running 60 metres long with sticky traps and pitfall traps every 15 metres. The point-quarter transect method was used to record surrounding tree species and diameter to provide further information about the areas biotic diversity. It was hypothesized that there would be a difference in invertebrate diversity between the two locations‚ as it is known that both abiotic and biotic factors of an environment

PHYLA (singular: phylum) Phyla can be divided into DIVISIONS Divisions are divided into CLASSES Classes are divided into ORDERS Orders are divided into FAMILIES Families are divided into GENERA (singular: genus) GENERA are divided into SPECIES Species are sometimes divided into VARIETIES The concept of the binomial system was introduced by Carolus Linnalus (1707-1778) in 1753 for flowering plants. The system gives each plant a name which is made up of two parts. The first part is called

and non-scientists proposed that life was not static throughout the years it wasn’t until the 19th century that Charles Darwin proposed a mechanism to scientifically explain how evolution could occur. In 1859 Charles Darwin published The Origin Of Species. Darwin made many observations that lead to the realization of the process of evolution. The first‚ all populations contain variation on a genetic level. The second‚ offspring inherit characteristics from their parents. The third‚ organisms with

He looked very precisely at the fossil records and noticed that some species changed physical features as time went by‚ eventually looking different from their ancestors. Many scientists had discussed evolution‚ but no one had a concrete theory such as Lamarck’s. He insisted that animals underwent physical changes in their

Microevolution and Macroevolution Microevolution is a inherited change in a population within the same species but this does not result in a new species. There are four factors that contribute to microevolution: mutation‚ gene flow‚ genetic drift‚ and natural selection. A mutation is generally a random change in the DNA. So for example‚ if a species of birds start developing shorter bills‚ then that is a genetic change. Gene flow is when a population migrates to a different area. The birds might
