The concept that organisms who are the best suited to their environment will be the most successful
What is natural selection
100
These simple molecules form the basis of all proteins
What are amino acids?
100
Which organisms have the most available energy in a food pyramid?
Producers
100
These are the products of cellular respiration
Water, carbon dioxide, and ATP
100
Are viruses living or nonliving? Why?
Nonliving; they cannot reproduce on their own...needs a host. (Does have DNA & evolve over time)
200
The grouping of cells that contain DNA, cytoplasm, ribosomes, and a cell membrane, but no other membrane-bound organelles.
What is a prokaryote? (or prokaryotic cell)
200
Which characteristic do all plants, animals, protists, and fungi have in common?
They are eukaryotic (have a nucleus)
200
A students 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
What is the basic unit of life?
Cell
200
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation
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
movement of ions, and molecules across cell membranes without the need for energy input
What is passive transport?
300
Both organisms benefit from this type of symbiotic relationship.
mutualism
300
The stage in meiosis 1 where crossing over occurs to create genetically different chromosomes from the originals
What is prophase 1?
300
If the producers contain 10,000 Kcal, then how much energy will the secondary consumers contain?
What is 100 Kcal?
400
What is the Cellular Respiration equation?
C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36/38 ATP
400
This process produces four genetically unique cells, each with half the number of chromosomes as in the parent
meiosis
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
State the Central Dogma of Protein Synthesis
DNA --> mRNA --> Protein
400
What tool would be used to help scientists predict genetic conditions or ideal traits?
Punnett Squares
500
The process by which water moves through the cell membrane to balance out a high concentration of solutes.
What is osmosis?
500
The formula for photosynthesis
CO2 + H2O —> C6H12O6 + O2
500
When both alleles are present they will mix to create a new phenotype/trait
What is incomplete dominance?
500
Find the Amino Acids
TAC - AGT - CTC
DNA: TAC - AGT - CTC
RNA: AUG - UCA - GAG
Amino Acids: MET - Ser - Glu

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?
