ORIGIN OF LIFE (SC.912.L.15.8)
These elements make up all known life on Earth, including carbohydrates, lipids, proteins, and nucleic acids.
What are carbon, hydrogen, oxygen, nitrogen (and phosphorus/sulfur)?
This term describes a trait that increases an organism’s ability to survive and reproduce.
What is an adaptation?
This type of evidence shows how species have changed over long periods of time.
What is the fossil record?
This element is found in all organic molecules and is the backbone of life.
What is carbon?
This structure controls what enters and leaves the cell.
What is the cell membrane?
This experiment showed that organic molecules could form under early Earth conditions.
What is the Miller–Urey experiment?
Natural selection can only occur if traits are this.
What are heritable?
Structures that are similar because of shared ancestry are called these.
What are homologous structures?
This macromolecule is made of amino acids and functions as enzymes, hormones, and structural components.
What are proteins?
This organelle is known as the “powerhouse” of the cell.
What is the mitochondrion?
What is the Cell Theory?
a fundamental biological principle stating that all living organisms are made of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells
This condition of natural selection occurs when more offspring are produced than can survive.
What is overproduction?
These structures have similar functions but evolved independently.
What are analogous structures?
This macromolecule stores genetic information in cells.
What are nucleic acids?
This process maintains stable internal conditions in living organisms.
What is homeostasis?
This scientist demonstrated that cells only come from pre-existing cells, disproving spontaneous generation.
Who is Louis Pasteur?
Over time, adaptive heritable traits become more _______ in a population.
What is common (or increase in frequency)?
Similarities in early embryos suggest this about living organisms.
What is common ancestry?
This type of bond holds amino acids together in a protein chain.
What is a peptide bond?
This type of transport moves molecules from high to low concentration without energy.
What is passive transport?
suggests that some organelles, notably mitochondria and chloroplasts that are found inside eukaryotic cells, were once simple free-living prokaryotes.
What is ENDOSYMBIOSIS THEORY?
Natural selection occurs if and only if variation in traits leads to differences in this.
What is fitness?
Comparing DNA and protein sequences provides evidence from this field.
What is molecular biology?
This macromolecule provides long-term energy storage and makes up cell membranes.
What are lipids?
This cellular structure is responsible for protein synthesis.
What are ribosomes?
