Endosymbiosis
Mutualism
Spontaneous generation
In the Miller-Urey experiment, the electrical sparks mimicked...
the Sun's energy
lightning
volcanic eruptions
cosmic radiation
Based upon the conditions of the early Earth, which forms of life most likely appeared first?
Prokaryotic and aerobic
Prokaryotic and anaerobic
Eukaryotic and aerobic
Eukaryotic and anaerobic
Which statement provides evidence for endosymbiosis?
Early prokaryotes contributed to a large increase in oxygen in the atmosphere.
Eukaryotic mitochondria and chloroplasts have their own circular DNA.
Eukaryotic mitochondria and chloroplasts have their own circular contain 80s ribosomes
Experiments by Miller and Urey produced simple organic molecules in abiotic conditions.
Pasteur carried out a series of experiments that provided strong evidence against a widely supported theory. What was this theory?
Endosymbiosis
Spontaneous generation
Conservative replication of DNA
Evolution
Pasteur’s experiment proved that:
Cells arise from pre-existing cells.
Cells come from spontaneous generation.
The first cell came from non-living material.
Broth can be a source of cells.
Identify the evidence that supports the taking in of mitochondria and chloroplasts by endocytosis, as part of the endosymbiotic theory.
Both mitochondria and chloroplasts have 80S ribosomes.
Both mitochondria and chloroplasts produce vesicles.
Both mitochondria and chloroplasts have double membranes.
Both mitochondria and chloroplasts have single membranes.
How did mitochondria originate (according to the endosymbiotic theory)?
From in-foldings of the plasma membrane, coupled with mutations of genes for proteins in energy-transfer reactions.
From engulfed, originally free-living proteobacteria.
From the nuclear envelope folding outward and forming mitochondrial membranes
When a proto-eukaryote engaged in a symbiotic relationship with a protocell.
What was formed in the Miller-Urey experiments?
amino acids
proteins
living cells
DNA
