What is the first step in the scientific method?
Making observations
100
What is the scientific definition of a population?
All of the organisms of the same species in a given area that can reproduce with each other.
100
What is the definition of abiotic and biotic?
non-living and living
100
List all four macromolecules!
Carbs, lipids, proteins, nucleic acids
100
Name two organelles and give their functions.
nucleus - houses DNA lysosome - garbage disposal mitochondria - cell respiration chloroplast - photosynthesis etc.
200
Give an example of: 1. qualitative data and 2. quantitative data
1. color, texture, any description 2. anything with a number
200
Define and give an example of density-dependent limiting factors and density-independent limiting factors.
dependent: depends on the density ex. predation independent: doesn't depend on the density ex forest fire
200
Draw an energy pyramid that explains the ten percent rule.
Drawing showing 90% of energy is lost
200
What is the physical difference between saturated and unsaturated fats?
Saturated fats are solid, unsaturated fats are liquid
200
Give the chemical equations for photosynthesis and cell respiration.
CO2 + H2O --> C6H12O6 + O2 C6H12O6 + O2 --> CO2 +H2O
300
List the three parts of a hypothesis.
If...then...because!
300
List three things that can create carrying capacity.
Lack of: food, water, space Disease, predation
300
Draw a food chain with at least four organisms and label them with good vocabulary words!
Autotroph, heterotroph, producer, consumer, herbivore, carnivore, omnivore
300
Name two factors that affect enzymes.
Temperature, pH, concentration of enzyme or substrate

You put a potato slice in a glass of fresh water. What will happen to it? (Use the words hypertonic/hypotonic, and osmosis)
It will get bigger because the potato is hypotonic to the water. When something is hypotonic osmosis pushes water into it.
400
What is an independent variable? What is a dependent variable?
What we change and what we measure
400
Give an example of a renewable resource and a non-renewable resource and one way humans could use each resource better.
(Example) renewable: water, keep it clean nonrenewable: oil, limit our use
400
Name the three kinds of symbiosis and give an example
Mutualism - pollinators Commensalism - barnacles on a whale Parasitism - tapeworms
400
Draw an exothermic and endothermic reaction graph.
(Can be drawn on board)
400
What is the difference between active and passive transport? Give an example of each.
Active uses energy. Passive example: osmosis Active example: endocytosis

Maddie wants to see how tall trees grow in different humidity levels: one outside and three at different levels inside a greenhouse. Tell me the IV, DV, control group, and two constants.
IV: humidity levels DV: height control: tree outside constants: water, soil, temperature
500
Draw an exponential and logistical growth graph. Label the carrying capacity.
Drawings.

What is the competitive exclusion principle?
Two organisms cannot occupy the same niche in the same ecosystem at the same time.
500
Give the function and an example of each of the four macromolecules (carbs, lipids, nucleic acids, and protein)
quick energy - sugar stored energy - butter genetic information - DNA lots of things! - meat

List 1. The two main reactions for photosynthesis and where they happen and 2. The three main reactions for cell respiration and where they happen.
1. Light dependent in the thylakoid and light independent in the stroma 2. Glycolysis in the cytoplasm, Krebs in the mitochondria, and ETC on the mitochondrial membrane
