Meiosis, Sexual Reproduction Sperm and Egg formation

FERTILIZATION The cell that results from fertilization is known as a ZYGOTE

PHOTOSYNTHESIS What is the word equation for photosynthesis? Carbon Dioxide + Water + Light Energy Glucose + Oxygen + Water

Crossing Over during MEIOSIS Variation This process results in __________________________

Photosynthesis

A hypothesis is written as: If I do this……….., then this will happen.

DAYS Day 0 and Day 5.5 or 6 The Independent variable is: Approximately on what day did both species have populations of the same size? Day 0 and Day 5.5 or 6 DAYS The Independent variable is:

What would be a hypothesis for the following problems? 1. Determine if mice like peanut butter more than they like cheese. If I give 100 mice the choice of peanut butter or cheese, then more mice would pick the cheese than the peanut butter. 2. What is the optimum pH for growing corn? If I grow corn in an acidic, neutral and basic soil, then the corn growing in neutral soil would grow best?

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 Abiotic means Living Non Living

PREDATOR/PREY

MUTUALISM (+, +) They both benefit

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

Biomass Pyramid or Energy Pyramid

Mitochondria site of________________ Cellular Respiration Do you know the word equation for respiration? Glucose + Oxygen ATP + Carbon Dioxide + Water

ANIMAL CELL Do you know what this is? Cell Membrane How about this? Nucleus And this? Mitochondria

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 Site of ______________ Cellular Respiration

C6H12O6 + 6O2 -----> 6CO2 + 6H20 + energy (heat and ATP) The equation above represents: Cellular Respiration

Homeostasis: Feedback Mechanism

PLANT CELL 1. Nucleus 2. Nucleolus 3. Cell Membrane 4. Cytoplasm 5. Cell Wall 6. Vacuoles 7. Chloroplast

Photosynthesis Producer Autotroph This organism makes its own food. Based On this type of nutrition we give this plant two names. What are they? Producer Autotroph

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.

Name that System Muscular Skeletal Lymphatic Circulatory Male Reproductive Digestive Female Reproductive
