Biology 1001 Final Exam Study Guide Chapter 1 What is Life? Key Concept=  Key Terms=  People= ­ Study of living organisms and how they function, develop, and evolve Key Concept: Order­ high degree of organization Living System in Order ● Maintain Order ● Metabolize Food ● Move ● Respond to the environment ● Reproduce ● Grow and Develop ● Pass genetic traits to offspring ● Evolve ● Adapt Explain the characteristics of each living system in order Order­ each activity or structure functions properly when the other is present Metabolism­ organisms obtain sufficient energy in their environment from food or sunlight Motility­ organisms can move about in their environment as long as bodily parts are functioning  properly Responsiveness­ organisms react to different changes in their environment whether it he from  food, water, temperature, or other elemental factors Reproduction­ organisms reproduce with their kind Development­ a new organism increases in size and complexity  Heredity­ genes are passed from parent to offspring which controls the overall behavior,  function, and form of an individual organism Evolution­ a gradual change that occurs over time where organisms find new ways to survive,  reproduce, and obtain energy Adaptation­ due to natural selection and evolution organisms must find efficient ways to better  live in their environment Two types of Reproduction: ­ asexual reproduction­ identical offspring is produced by one parent ­ sexual reproduction­ similar not identical offspring is produced by two parents  Key Concept: Hierarchy of Order: There must be some degree of order when it comes to living things and its complexities Order of Hierarchy ­ organism ­ organ system ­ organ ­ tissue ­ cell ­ organelle ­ molecule Explain the functions of the hierarchy  Key Terms: Organisms­ individual Organ System­ group of body parts that help carry out bodily functions Organ­ consisting of many tissues this structure carries out bodily functions Tissue­ particular functions are carried out by a group of similar cells Cell­ contains all the properties of life and is the least complex Organelle­ structure within a cell that performs a special function Molecule­ chemical bonds hold clusters of atoms together People: Biologists­ help us better understand more than 50 million groups on earth by creating a system  of classification Key Concept: Classification of living things­ Evolution creates diversity 2 Characteristics of Evolution Species:  ­ Individuals not only breed within a group, but they also share in similar structures that was passed on from the same group Genus: ­ Contains several related and similar species  2 Names  Felis Catus­ house cat Felis Paradise­ ocelot Hierarchy of Cat Species: The Classification Scheme ● Domains ● Kingdoms ● Phyla ● Classes ● Order ● Families ● Genera ● Species Key Terms: 3 Domains ­ Bacteria is a variety of prokaryotic species ­ Archaea are prokaryotic species that often inhabit harsh environments ­ Eukarya are larger more complex eukaryotic cells that contain four kingdoms  Define Unknown Terms: Eukaryotic Cell­ protista, plants, fungi, and animals contain a working nucleus as well as other  organelles enclosed in a membrane  Prokaryotic Cell­ singled celled organism that lacks a membrane­bound nucleus, mitochondria,  or any other membrane­bound organelle  Key Terms Cont.  Unity­ all living organisms share a common ancestor Diversity­ organisms are able to better adapt to their habitat due to the process of evolution * Life is unified and diverse Adaptation­ helps an organism adapt to its environment (food, water, energy) ­Helps an organism better develop and reproduce  EX.  ● White foxes can only live in areas (terrain) where there is snow and cold  temperatures ● Brown foxes better adapt in woods and forests where temperatures are mostly  warm and humid Key Term: Natural Selection: nature chooses those who are most suitable to live and survive in an  environment so that a new generation can be reproduced *In order for adaptation to occur natural selection must take place and during this process the  weak are “weeded out”  ­ An organism’s hereditary traits as well as their ability to reproduce and obtain  energy in a specific environment depends on how well they adapt  People: Charles Darwin­ coined the term natural selection in 1859 and published a book on “The Origin  of Species” Key Concept: Ecology: the relationships between living organisms and the environment that they live in are studied The Hierarchy of Ecology ● Biosphere ● Biome ● Ecosystem ● Community ● Population   Key Terms: Biosphere­ all of earth’s ecosystems Ecosystem­  both living communities and its nonliving physical surroundings together

Scientists­ study life by looking to natural causes and the fundamental laws of nature  ­Laws of nature still operate the same today as it did a million years ago ● Speed of Light ● Gravity ● Properties of chemical elements  How are scientific puzzles solved by scientists? ● Developing and generalizing a theory by studying particular cases  ● Specific cases have generalized theories  Key Concept: Steps in the Scientific Method  ● Identify a problem ● Propose a hypothesis ● Make a prediction ● Test the prediction  ● Draw a Conclusion Key Terms: Control Group­ Variable being tested is absent (placebo) Experimental Group­ Variable being tested is present * Testing both groups so that you can analyze the results and draw a conclusion  What can help society find solutions for biological advances ● overpopulation ● famine ● disease ● ozone depletion ● loss of species ● Life on other planets?
