Cells
"powerhouse of the cell" produces ATP for energy
mitochondria
These four nucleotides make up DNA: A, T, G, and this letter
What is C (Cytosine)?
This scientist proposed natural selection on the Galapagos Islands
Charles Darwin
This pigment captures light energy in photosynthesis
chlorophyll
The role an organism plays in its environment
niche
This organelle is responsible for protein synthesis and contains ribosomes
endoplasmic reticulum
This process copies DNA into messenger RNA
What is transcription?
The process where organisms better adapted to their environment survive
natural selection
This molecule is broken down in cellular respiration to produce energy
glucose
A relationship where one organism benefits and the other is harmed
parasitism
This structure controls what enters and exits the cell
cell membrane
This type of RNA carries amino acids to ribosomes
What is transfer RNA (tRNA)?
These features in different species have similar basic structure but different functions
homologous structures
This cycle in photosynthesis fixes carbon dioxide into glucose
Calvin cycle
The maximum population an environment can sustain
carrying capacity
These structures help plant cells maintain rigid structure and prevent bursting
cell walls
This enzyme unzips and copies DNA during replication
What is DNA polymerase?
Inherited characteristics that improve survival and reproduction are called
adaptations
This process produces ATP without oxygen
fermentation
this describes the transfer of energy between trophic levels
ecological efficiency
This organelle contains hydrolytic enzymes that break down cellular waste
lysosomes
These three nucleotide sequences signal where protein synthesis should stop
What are stop codons
This principle states that populations remain stable unless acted upon by outside forces
Hardy-Weinberg equilibrium
This electron transport chain process pumps hydrogen ions to produce ATP
chemiosmosis
This principle states no two species can occupy the same niche
Competitive exclusion
