Cyanobacteria and purple sulfur bacteria both obtain energy from light. however, only the ________ are capable of releasing ____
kap26 [50]

Answer: Cyanobacteria, oxygen

Cyanobacteria also known as Cynophyta and blue green algae. It is a phyllum of bacteria that produces it's own food like plants by the process of photosynthesis. It is found in freshwater lakes, damp soils, oceans, moistened rocks and even in animal fur. The purple sulfur bacteria belongs to the group of Proteobacteria. It is an anaerobic bacteria. It is found in hot springs, and stagnant water. It is a photosynthesizing bacterial strain like Cyanobacteria but it does not utilize water to be reduced in the photosynthesis process like in Cynobacteria, to produce oxygen.

Hence, only the <u>Cyanobacteria</u> are capable of releasing <u>oxygen</u>.

Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within _______.
horsena [70]

Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within 24 hours.

Cryopreservation of Red blood cells (RBCs) can be done with a long time span of usability of 10 years. Glycerol safeguards RBCs during freezing and defrosting, yet it can cause hemolysis if it is not washed off or eliminated before transfusion. When a unit has been deglycerolized, the shelf life of RBCs in an open system is only 24 hours, bringing about sporadic utilization of Frozen RBCs from the outset of the procedure or in close system cases it is up to 14 days.
