This seasonal fur color change in the arctic fox is an example of: Environment the _____________ GENE affecting _________ _________________ Expression A hypothesis is: An educated guess Or a predicting statement What would be a hypothesis for the following problem? What is the optimum pH for growing corn? Corn grown in acidic soil will grow best. Or Corn grown in a basic soil will grow the most. Chromosome ______________, which is made up of _______________ Tightly coiled _______________ DNA ______________. A segment of this DNA is called a GENE _______________. A chromosome contains many GENES ____________ The cells of these organs are genetically identical ____________________. However, they look and function differently because: they each express a different set of genes Ecological Succession Pioneers Stage 1 vegetation are called ________________ While stage 5 vegetation is called the ________________ Climax vegetation Food Chain Based on the hawks feeding Habits it could be called 4 Different names. Can you name Them? A. Carnivore B. 4 level Consumer C. Predator D. Heterotroph Grasshopper eats grass Grass ECOSYSTEM What makes this an ecosystem? It has both biotic and abiotic factors Biotic means Living Abiotic means Non Living Ecological Succession Abiotic Factors (Nonliving) PHOTOSYNTHESIS What is the word equation for photosynthesis? Carbon Dioxide + Water + Light Energy Glucose + Oxygen + Water PREDATOR/PREY PARASITISM (+, -) GLOBAL WARMING Caused by ________________________ Greenhouse gases like ______________, Carbon Dioxide _____________ Methane gas Water vapor Chlorofluorocarbons (CFCs) ___________________, ________________________________. Comparative Anatomy According to evolution they are similar because they have a __________________, Common ancestor But they are different because each has __________________________________ Adapted to specific environments or niche. Protein Synthesis Name the red structure: Name the green structure: Name the Orange structure: Name the purple structure: Messenger RNA (mRNA) Transfer RNA (tRNA) Ribosome Amino acids forming a polypeptide or protein MUTUALISM (+, +) Consequences of GLOBAL WARMING EVOLUTION These remora fish attached to this shark do not harm the shark. However they benefit as They get a free ride and left over food as the shark feeds. Based on the description above this relationship can be described as: Commensalism (+, 0) Note: We use a zero for the shark because he is not harmed nor does he benefit OZONE LAYER DEPLETION Chlorofluorocarbons (CFCs) Caused by ______________________________________ DEFORESTATION Reforestation The opposite of deforestation is ________________________ Gradualism Punctuated Equilibrium Industrial Melanism Stanley Miller’s experiment What hypothesis was this experiment working on? The Heterotroph Hypothesis FERTILIZATION The cell that results from fertilization is known as a ZYGOTE Crossing Over or recombination during MEIOSIS Variation This process results in __________________________ Genetic Engineering or Gene Splicing Meiosis, reduction in chromosome number Biomass Pyramid or Energy Pyramid Menstrual Cycle List 4 Hormones involved: LH, FSH, Progesterone and Estrogen differentiated Stem Cells or cells that are not______________ Mitochondria site of________________ Cellular Respiration Do you know the word equation for respiration? Glucose + Oxygen ATP + Carbon Dioxide + Water DNA or Deoxyribonucleic acid List 3 ways it differs from RNA 1. It is double stranded, RNA is single stranded 2. DNA uses Deoxyribose as its sugar, RNA uses Ribose 3. DNA uses Thymine (T), RNA uses Uracil (U) C A B A: Uterus, site of development of the fetus D B. Ovary: Produces hormones and also stores and releases eggs. C. Fallopian Tubes or Oviduct, site of fertilization D. Vagina: Receives sperm and it is the birth canal. Genetic Engineering Or Gene Splicing Genetic Engineering or Gene Splicing ANIMAL CELL Do you know what this is? Cell Membrane or Plasma Membrane How about this? Nucleus And this? Mitochondria Protein Synthesis Using colors identify: mRNA Red and White tRNA Ribosome Green Yellow DNA Replication Diffusion Placenta What is the function of the placenta? It is the site of Exchange of nutrients And waste products Between the baby And the mother. Respiratory System Name two systems that work Closely with the respiratory System. Circulatory System Brings Carbon Dioxide to the Lungs and gets Oxygen Nervous System Monitors level of Carbon Dioxide In the blood to determine our Breathing rate. What does each system do? Mitochondria Cellular Respiration Site of ______________ C6H12O6 + 6O2 -----> 6CO2 + 6H20 + energy (heat and ATP) The equation above represents: Cellular Respiration There are two kinds of cellular respiration. Name them. Aerobic Respiration Requires Oxygen Anaerobic respiration Does not require Oxygen How are the two different? PLANT CELL 1. Nucleus 2. Nucleolus 3. Cell Membrane 4. Cytoplasm 5. Cell Wall 6. Vacuoles 7. Chloroplast Osmosis Because it deals with the diffusion of WATER Biomass Pyramid List all the names that Apply to the caterpillar Herbivore 1st level consumer heterotroph Antibodies attaching antigen To _______ Protein synthesis List four types Of proteins found in our bodies: 1. Enzymes 2. Antibodies 3. Neurotransmitters 4. Hormones Photosynthesis This organism makes its own food. Based On this type of nutrition we give this plant two names. What are they? Producer Autotroph Name that System Muscular Skeletal Digestive Circulatory Female Reproductive Lymphatic Male Reproductive Homeostasis Name the producer in this pyramid. Grasses because they are autotrophs Who can be considered a 2 level consumer? Chipmunks are 2 level, While insects are 1st level Which individual would Be the least numerous? Grizzly bears would be The least because of Energy and biomass loss From one trophic level top the next. Photosynthesis
