Fossil evidence indicates that the first organisms on Earth were single-called prokaryotes. The first eukaryotes are believed to have formed from these prokaryotes. How does the endosymbiotic theory explain the development of the first eukaryotic organisms?.
The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells. The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.

what conditions prompt hemoglobin to release oxygen? select the three answers that are correct.
The conditions that prompt hemoglobin to release oxygen are:
Decrease in pH (high acidity)ExerciseUnloading of oxygen from haemoglobinHaemoglobin is the blood protein that is used to carry oxygen in our body and gives blood its red colour. The ability of this protein to carry oxygen depends on some factor. These factors include:
Decreased pH: Upon the production of carbondioxide in the tissue cells, carbonic acid is produced which leads to decrease in pH of the blood. Exercise: During exercise, the temperature of muscle increases secondary to its utilisation. This will cause the release of unloading of oxygen from haemoglobin.Therefore, conditions that prompt hemoglobin to release oxygen are decrease in pH (high acidity) and exercise.
