The concept that organisms who are best suited to their environment will be the most successful and pass on their genes.
What is natural selection
100
These are the products of cellular respiration
water, carbon dioxide, and ATP

What is REAL!
200
The process by which water moves through the cell membrane to balance out a high concentration of solutes.
What is osmosis
200
The grouping of cells that contain DNA, cytoplasm, ribosomes, and a cell membrane, and a cell membrane, but no other membrane-bound organelles
What is a prokaryote? (or prokaryotic cell)
200
A student observes a cell where the chromosomes appear to be pulled apart by spindle fibers. These two final steps would come after this.
What are telophase and cytokinesis?
200
A biomolecule that serves as a fast source of energy?
What are carbohydrates?
200
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation
300
The legs of crocodiles and cats have similar bone structures and develop in a similar way which indicates a common ancestor. What type of structures are the leg bones?
What are homologous structures
300
The three organelles found in a plant cell but not an animal cell
What are cell walls, large central vacuoles, and chloroplast?
300
This RNA is transcribed from a section of DNA and later leaves the nucleus in order to be translated into an amino acid chain
what is mRNA?
300
This process occurs when less oxygen is present in an organism, resulting in less ATP energy produced. It can also lead to fermentation.
What is anaerobic cell respiration?
300
movement of ions, and molecules against cell membranes with the need for energy input
What is active transport
400
Organs/parts many animals still have but are no longer used.
What are vestigial structures?
400
A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
What is a keystone species?
400
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent
meiosis
400
The stage in meiosis 1 where crossing over occurs to create genetically different chromosomes from the originals
What is prophase 1?
400
If the producers contain 10,000 Kcal, then how much energy will the secondary consumers contain?
What is 100 Kcal?
500
The formula for photosynthesis
CO2 + H2O —> C6H12O6 + O2
500
This is the process by which organisms break down glucose, without the use of oxygen, to create ATP
What is anaerobic cellular respiration?
500
When both alleles are present they will mix to create a new phenotype/trait
What is incomplete dominance?
500
Sickle cell anemia is a recessive disease. If you cross two parents with the alleles Aa x Aa, what are their children's chances of having sickle cell anemia?
What is 25% have sickle cell?
500
What is the DNA strand to this RNA strand
AUG - UCA - GAG
TAC - AGT - CTC
