The concept that organisms who are the best suited to their environment will be the most successful
Natural selection
100
These simple molecules form the basis of all proteins
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

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?
Homologous structures
200
The grouping of cells that contain DNA, cytoplasm, ribosomes, and a cell membrane, but no other membrane-bound organelles.
Prokaryotic cell
200
The minimum quantity of energy that is required to activate atoms or molecules to a condition in which they undergo a specified reaction.
Activation energy
200
What do enzymes do?
Speed up chemical reactions by reducing activation energy
200
A biomolecule that serves as a fast source of energy?
Carbohydrates
200
Any inherited trait that increases an organism's chance of survival is known as this.
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.
mRNA
300
movement of ions, and molecules across cell membranes without the need for energy input
Passive transport
300
Water molecules have attractive forces to one another and are held together by these types of weaker bonds
Hydrogen bonds
300
During meiosis, what is the purpose of "crossing over"?
To ensure that all gametes are different, increasing genetic diversity of the offspring.
300
If the producers contain 10,000 Kcal, then how much energy will the secondary consumers contain?
100 Kcal
400
Organs/parts many animals still have but are no longer used.
Vestigial structures
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.
Keystone species
400
This is the process by which organisms break down glucose, without the use of oxygen, to create ATP
Anaerobic cellular respiration
400
The three organelles found in a plant cell but not an animal cell
Cell wall, large central vacuole, and chloroplast
500
The process by which water moves through the cell membrane to balance out a high concentration of solutes.
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

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?
25% have sickle cell
