What are the non living things in an organism's environment called?
abiotic factors
100
All organic molecules contain which element?
Carbon
100
What is the main function of the cell membrane?
controls the movement of materials into and out of the cell
100
In which organelle does photosynthesis occur?
Chloroplasts
100
What is the difference between a food web and a food chain?
A food web shows a realistic path energy travels through a specific ecosystem.
A food chain shows one part of a food web representing only one path energy takes through a part of an ecosystem
200
What percentage of energy gets passed on at each trophic level?
10% (The 10% Rule)
200
What is the smallest basic unit of matter?
An atom
200
What is the jelly like substance that fills the inside of a cell called?
Cytoplasm
200
In which organelle does cellular respiration occur?
Mitochondria
200
What are the four main elements in most macromolecules?
CHON = Carbon, Hydrogen, Oxygen, and Nitrogen
300
Look at the food web provided. If the Owl population increased, which species would most likely decrease?
The frog and the mouse because there would be more predators to eat them.
300
What are the charges of a proton, a neutron, and an electron?
Proton = positive
Neutron = neutral/no charge
Electron = negative charge
300
What are the three organelles that plant cells have but animal cells do not?
Cell Wall
Central Vacuole
Chloroplasts
300
What form is the energy created during cellular respiration stored in?
ATP (adenosine triphosphate)
300
What is the function of a lysosome in the cell?
Cleaning the cell by breaking down old worn out cell parts
400
What are three resources animals might compete over?
Space, Food, Water, a mating partner(reproduction), sunlight, shelter
400
What are the four macromolecules we discussed this year?
Proteins, Carbohydrates, Lipids, and Nucleic Acids
400
What is the difference between a prokaryotic and eukaryotic cell?
Eukaryotic cells have a nucleus and membrane bound organelles. Prokaryotic cells do not
400
What are two products created during photosynthesis?
Glucose (sugar) and Oxygen
400
Name 2 inputs necessary for photosynthesis.
Carbon Dioxide, Sunlight, and Water
500
What is a carrying capacity and why might it reach a maximum amount?
Carrying capacity is the maximum number of individuals an environment can support. The carrying capacity is determined by limiting factors such as the food , space, water, or shelter available.
500
Name the monomers for any two of the macromolecules we discussed this year.
Proteins = amino acids
Lipids = Fatty acids
Carbohydrates= monosaccharides
Nucleic Acids = Nucleotides
500
What is the difference between passive and active cell transport?
Active transport requires the use of energy, passive transport does not
500
How do photosynthesis and cellular respiration work together in the carbon cycle?
Photosynthesis breaks down carbon dioxide(CO2) and creates glucose and oxygen. Cellular Respiration breaks down Glucose and Oxygen creating Carbon dioxide and ATP.
500
What is osmosis?
when water molecules move through a cell membrane from high concentration to low concentration
