Maintaining internal balance
What is homeostasis?
The variation of life
What is biodiversity?
Write the chemical equation for photosynthesis.
What is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
The main difference between prokaryotic and eukaryotic cells?
What is Prokaryotic have no nucleus and Eukaryotic do have a nucleus
Which biomolecule provides quick energy for cells?
What is Carbohydrates
Movement of molecules from high to low concentration
What is diffusion?
List the 8 levels of classification from highest to lowest
What is Domain, Kingdom, Phylum, Class, Order, Family, Genus, species
Write the chemical equation for cellular respiration.
What is C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Cell types that have membrane-bound organelles?
What are Eukaryotic cells
Which biomolecule stores genetic information?
What is Nucleic acids (DNA/RNA)
Compare passive and active transport.
What is...
Passive: no energy, with gradient;
Active: requires energy, against gradient
How much energy is transferred between trophic levels in the food pyramid?
What is 10%
Compare the energy flow in photosynthesis and respiration.
Photosynthesis stores energy; respiration releases energy
Compare DNA in prokaryotes and eukaryotes.
What is
Prokaryotes: circular DNA in cytoplasm; Eukaryotes: linear DNA in nucleus
Compare the roles of proteins and nucleic acids in cells.
What is Proteins functions are: structure, enzymes, transport and Nucleic acids = genetic information
How does osmosis affect plant cells in hypertonic and hypotonic solutions?
What is Hypertonic: cell shrinks; Hypotonic: cell swells
Evolution of an organism's traits that allow them to better adapt to their environment; survive, reproduce, and pass on this trait.
"Survival of the fittest"
What is "Natural Selection"
The absence of oxygen produces lactic acid as a product and 2ATP
What is Anaerobic Respiration
How do ribosomes differ in prokaryotic and eukaryotic cells?
What is
Prokaryotes: smaller ribosomes; Eukaryotes: larger ribosomes
Which biomolecule makes up cell membranes, and why is it important?
What is Lipids (phospholipids); create a selective barrier
Explain how transport of molecules across membranes helps maintain homeostasis.
what is Controls nutrients, gases, wastes to keep stable conditions
The strongest evidence of evolution. It classifies by comparing DNA. "Cladograms"
What is Comparative Biochemistry
Use a model to explain how energy is transferred in photosynthesis and respiration.
What is Sunlight → glucose (photosynthesis) → ATP (respiration)
Explain why prokaryotic cells can reproduce faster than eukaryotic cells.
What is that Prokaryotic cells have simpler structure and reproduce by binary fission which is quicker than mitosis.
Explain how the structure of enzymes allows them to carry out their function.
What is Enzyme shape (active site) fits specific substrates; lock-and-key model
