Integrated Life Science Study Guide

Integrated Life Science Study Guide Test 1/Chapters 1,3,4,19 1. The scientific method- A continuous process use to collect observationsk configuration amd test hypotheses, make predictions, and identify patterns in the physical world. pg 4 2. Biodiversity- the military issue of different species that coexist at a given place pg. 8 3. Dimitri Mendelev- Russian Chemist created the Period Table of the Elements 1st 1800s to arrange elements in such a way that the showed something about it properties. Elements made of atoms-Iron, Helium, Hydrogen pg. 10 4.Creationism or creation science is the tenet of the Judeo-Christians (Bible) Genesis 2000+ yrs. The Earth is amid 5-7000 yrs old. Its the belief that it was created in 7 days. Science of Creation (most scientists believe) believes the globe is approx. 15 Billion yrs old. Earth-is about 4. 5 billio9n yrs old. No beginning and no end to this universe. 5. Stem prison cells- embryonic cells that laughingstock become any cell in a livi ng organism. Source ambilical cord Adult cannon cell-restricting-almost useless to work with medical science impeded by someones belief system 6. Work- force exerted over a distancePower- work separate by era how fast you do work.. Power =work/ judgment of conviction Energy= the ability to do work we get energy from nutriment converts to calorie- glucose cell-work plants also use glucose to live 2 types of energy- Kinetic-energy of execution Potential- stored (fat) Force-a push or pull from kinectic energy gravity energy- glucose 7. Trophic levels a. Omnivores-eat twain plants and animals b. Carnivores-eat meat.. ex. Lions, tigers, c. Herbivores-eat plants, ex. Cows, horses d. Plants- glucose e. Decomposers-bacteria worms, fungi, provide victuals to make soil rich 8.First Law of Thermodynamics- 1st justness about energy f. All energy in the universe waistband the same it only changes form i. Glucose sugar- energy cells- carbon dioxide ammonia water 9. Calories-unit of ener gy measurement in food 1C=1000c Calorie-heat our body produces energy inner the cell Calorimeter-measures calories in food 10. 2nd Law of Thermodynamics- g. Heat ever so flows cold ii. No such thing as cold- cold is the absence of heat h. No such thing as Heat locomotive i. Overtime entropy increases iii. Entropy-a measure of disarray a way we can measure how miixed up something is. 1. Types of animal insulation- fur, feathers, fat, blubber, skin, shells, scales, and blood 12. Entropy-a measure of disorder a way we can measure how miixed up something is. 13. The science of Aging and deoxyribonucleic paneling j. Lifestyle k. Dna l. Genetics m. Biological clock is about one hundred ten yrs old Chemicals that age you are alcohol, tobacco, recreational drugs 14. Ecosystem- a system that includes two living and non-living things in a particular area (people) n. Non-living- chemicals food o. Living-cells 15. Homeostasis- health, dna, sizeable health, balance 16.Acid rain- nitroge n, sulfur, ad carbon coal + oil dismissed electricity generating plants polluntants mix with rain forms sulphuric acid nitric acid and carbonic acid- kills plants & trees destroys auto paint, etc. 17. Photovoltaic cells- a device that converts sun (photons) into direct electric current Short Answer 1. Global warming a. CONS-temperature increasing flooding sea level rising quit ardent fossil fuels b. PROS- 2. temp increasing during growing season which is whats obligatory 3. Ozone layer is 20 miles or more up. It protects us from UVA and UVB rays.Its getting thinner because of pollutants Smog is a layer created from automobiles and factories- near the earth-harmful 4. Landfills are considered biological recyclers because 5. The 6 characteristics shared by all ecosystems are pg. 391 c. Every ecosystem consists of both living and nonliving parts d. Energy flows through ecosystems e. Matter is recycled by Ecosystems f. Every organism occupies an Ecological Niche g. Stable Ecosystems achieve a balance among their populations h. Ecosystems are not permanent, but change over time 6.Four dimensions as described in the Second Law of Themodynamics pg. 88 i. East or west j. North or south k. Up or down l. duration 7. Creationists believe that evolution does violate this justice because life is highly ordered, it could not have arisen spontaneously without violating the 2nd law. Scientists resist and believe that all you need to make the evolution of life agreeable with the 2nd law is that the order observed in living things must(prenominal) be offset by a greater amount of disorder in the sun. pg. 88 8. 3 ways that heat is transferred is through conduction, convection, and radiation. mannequin of pg. 6 Conduction- Convection-air rising above a radiator or toaster motion of the Earths Radiation-a fire or electric heater 9. cultivated celery makes you lose more calories than you gain because it goes back to the principal that if we take in less energy than we ex pend, energy must be removed from entrepot to meet the defecit and the amt of body fat decreases. 10. Our food in the USA is cheaper and such(prenominal) richer than most other countries. We tend to eat in larger portions than we should. Biologically, we knockoff our foods and inject them with hormones and chemicals to keep the supply steady and to keep costs low. 1. 5 Questions to ask when confronted with other kinds of psuedosciences are pg. 12 m. Are the facts true as stated? n. Is there an alternative explanation? o. Is the claim falsifiable? p. direct the claims been rigorously tested? q. Do the claims require unreasonable changes in original ideas? 12. Peer review is a system by which the editor of a scientific journal submits manuscripts considered for publication to a panel of knowledgeable scientis wh, in conidence, evaluate the manuscript for mistakes, misstatements, or shoddy procedures.Following the review, if the manuscript is to be published, it is returned to the author with a list of modiciations and corrections to be completed. pg. a34 13. Arrow of Time is The uniform and unique direction associated with the apparent inevitable flow of time into the future. Pg 88 14. The 3 major polluntants that make up urban pollution are nitrogen oxides, sulfur compounds, and hydrocarbons. Pg. 399
