Which statements are part of the theory of endosymbiosis? select all that apply. early prokaryotes were able to carry out aerobic respiration and were engulfed by eukaryotic cells. the first cells that appeared on earth were eukaryotic and were engulfed by prokaryotic cells. early anaerobic prokaryotes engulfed aerobic prokaryotes, which evolved into mitochondria. some early eukaryotic cells engulfed photosynthetic prokaryotes, which evolved into chloroplasts.
7. Since all cells originated from a single-celled zygote, itmeans that they must contain the same DNA. If this is true,how

The infrared (ir) and the ultraviolet(uv) represent the two extremities of the visible spectrum (400-700nm). while ir represents electromagnetic radiation with wavelengths longer than those of visible light, uv represents wavelengths shorter than visible light
Early anaerobic prokaryotes engulfed aerobic prokaryotes, which evolved into mitochondria.
The endosymbiotic theory is used to explain the evolution of eukarytotic cells. They evolved from a predatory relatioship between anaerobic protists and aerobic prokaryotes that turned symbiotic.
It is believed that the very first cells utilized glycolysis for cellular respiration to provide energy for the cellular activities. Over time some cells evolved mechanisms to harness the energy of the sun. These cells changed the composition of the atmosphere because they took up carbon dioxide from the atmosphere and evolved oxygen resulting to what is described as the Great Oxygenation Event. Some cells evolved aerobic respiration with most anaerobes perishing due to the oxidative capacity of oxygen. These aerobic cells (the prokaryotes) were more efficient in producing energy than anaerobes.
During these times before evolution of autotrophs cells, cells were mainly heterotrophs meaning they engulfed other cells for ‘food’. These protists engulfed the prokaryotes that were more efficient in harnessing oxygen to create more energy. The prokaryotes utilized the Citric cycle than is highly effective in generating more energy than glycolysis. Over time this relationship shifted from predation to mutualistic relationship.
This relationship created the eukaryotic cells with the mitochondria being the aerobic prokaryotes that were engulfed by anaerobic protists.
To understand more about the differences between glycolysis and Krebs cycle check out;
1. a host loses nutrients to a parasite
2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )
3. producers to consumers
4. the tapeworm is a parasite
5. they convert energy from the sun (photosynthesis)
6. sunflower-robin (i think im 80% sure)
10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
