Introduction to Biology Remember A group of students hypothesize An independent variable is the that the amount of alcoholvariable that YOU have control over produced in fermentation A dependent variable is the depends on the amount of.variable that RESPONDS to what glucose supplied to the yeast you do They want to use 5 10 15 A control group is the group that 20 25 and 30 glucosedoes not receive the treatment solutions These are the data Read the scenario . Glucose Amt of alcohol l What is the independent variable What is the dependent variable 5 1 What would be a good control 10 13group 0 glucose. What conclusion could thestudents make based on the 20 30results more alcohol is produced 25 39at higher glucose concentrations Characteristics of Life. Read the scenario and on Sharks have many sub species your answer sheet underline This is a result of themall of the characteristics of life evolving over time to fill anthat the organism shows available niche Althoughsharks do not have bones .they are made of cartilage They are a multi celledorganism They reproduceand give birth to live young They are carnivorous feeding.only on meat Most sharks arecold blooded although a fewspecies are warm blooded For both it is vital that theymaintain homeostasis . Food Chains and Food Webs Identify a food chain in thefood web with fourorganisms Write it down Plant P Grasshopper 1st.C frog 2nd C owl 3rd C Label the producer primaryconsumer secondaryconsumer and tertiary How much energy is.transferred between eachtrophic level 10 moves up What is the differencebetween a food web and afood chain More complex.and realistic Carbon Cycle Examine the picture How does carbon enterbelow Answer the the food chain questions that follow CO2 picked up by plants. What two ways arehumans negativelyimpacting the carbon burning FF deforestation. How are nutrient cyclesdifferent from energy Matter cycles energytravels in one direction Water Cycle 5. Record the five steps of Examine the picturethe water cycle below Answer the Evaporation.questions that follow Condensation Precipitation Runoff infiltration.

What organism is Examine the picture responsible for fixingAnswer the questions nitrogen so that it isthat follow usable by plants bacteria. How do consumers gettheir nitrogen Eat someone How is nitrogen returnedto the soil .

Lichen is a fungi algae mutualist that can grow on rockand help form soil Secondary SuccessionSuccession Something happens to an area disrupting and destroying the.living things but leaving soil Grasses and small plants come in Larger plants shrubs and fast growing trees come in as domore animals A mature climax community develops. Secondary succession starts with soil while primarysuccession starts with bare rock Succession Secondary succession occurs faster because soil isalready present soil takes a looooong time to form . Primary succession would occur after a volcanic Secondary succession would occur after a man made or natural disaster like a fire or clear cuttingClear Cutting deforestation Forest Fire.Volcanic Eruption Threats to Biodiversity Biomagnification Biomagnification is thebuild up of a persistent.toxin within a food As the toxin moves upthe food chain itbecomes more andmore concentrated. So the top predatorreceived the most Threats to Biodiversity The greenhouse effect agood thing because it keeps.our planet warm Global warming may be badthing and it may behappening faster than Rising sea levels changing. Burning of fossil fuels coal oil and natural gas Very hot animals Dry Conserve water by little Vegetation includes waste.cacti Being nocturnal plants Waxy coating todecrease water loss Spongy inner tissue to.store water Temperate Deciduous Forest 18 animal Our biome Hibernate when it is cold Four seasons Shed in summer grow a. Deciduous and thick coat in winterconiferous trees Plant Lose leaves to saveenergy in winter withless sunlight. Broad leaves to catchlots of light during Tropical Rainforest Humid Biodiversity is a variety of Wet living organisms in an area. Has the mostbiodiversity Biodiversity is important Rapidly being because of the beauty and value of the livingdestroyed .organisms for food medicine and resources Animals that can live here are Cold harsh winters tolerant of cold artic fox or Layer of permafrost have short lifecycles mosquitos. They may migrate to warmer Vegetation cannot growareas too elkvery tall White fur or feathers acts ascamouflage. There is too little soil andwater for many plants to growtall so there are only short Three parts of the cell theory 1 All living things are made of.2 Cells are the basic units ofstructure and function inliving thing3 All cells come frompreexisting cells. Q Enzymes are what kind of macromolecule A Proteins What kind of macromolecule is this Is it a mono di or polysaccharide What are the four types of.macromolecules 1 Carbohydrates CHO 2 Lipids CHO 3 Proteins CHON 4 Nucleic acids CHONP .What does organic mean Organic compounds contain both carbon and What kind of macromolecule are fats andoils LIPIDSQ What part of the cell is made of lipids .A Cell membrane Q What kind of macromolecule is DNA Nucleotidebackbone KeyA Nucleic Acids. What organism is this BacteriumIs it pro or eukaryotic What is the tail like structure called MitochondrionGolgi body.What is the flagellum for Movement What are two things plant cells havebut animals cells don t Smooth endoplasmicVacuole reticulum.ChloroplastCell attached Cell wall NuclearMitochondrion Rough endoplasmic reticulumWhat is the function of the.chloroplast Photosynthesis Structure and Function Mitochondria Cite of cellular respiration Chloroplast Photosynthesis Lysosome Digest macromolecules. Vacuole Storage of water and minerals Ribosomes Site of protein synthesis Cell membrane regulates what enters and leaves the cell Nucleolus Ribosomes are made here Golgi Body Package and modify proteins. Which one is the final result of diffusion Diffusion is the movement of molecules from an area of higherconcentration to an area of lower concentration Facilitated diffusion uses a protein to carry moleculesacross the membrane because the molecules are to.big to diffuse by themselves What kind of cellular transport requires theuse of ATP energy Active transportIt require ATP energy because it transports moleculesagainst the concentration gradient . What is happening in endocytosis Molecules are being activelytransported into the cell Interphase and Mitosis are the two parts of the cell cycle DNA is replicated during the S phase of interphase . In order from big to small Cell nucleus chromosome DNAChromosome In mitosis a parent cell divides to formhow many daughter cells Two.In mitosis what kind of daughter cellsare formed Identical diploid cells A cell before it does mitosis is in whatphase Interphase What phase of mitosis is this Metaphase.What phase of mitosis is next Anaphase What phase of mitosis is this AnaphaseWhat phase of mitosis is next telophase What is this structure What are some things ATP is used.for in a cell Q When energy is made by a reaction is it exergonicor endergonic A ExergonicIn an exergonic reaction is ATPmade or used up made.
