Answer:

Diatoms are single-celled algae that live in houses made of glass. They are the only organism on the planet with cell walls composed of transparent, opaline silica.  Cyanobacteria is also called nitrogen fixers because cyanobacteria fixes atmospheric nitrogen in the soil in the available forms of nitrogen to the plants.

Gnesinka [82]
Typhitis, also called neutropenic enterocolitis, is an infection that often develops in cancer patients who undergo chemotherapy. In many cases, surgical intervention is required.

Without surgical intervention, the patient would be transferred to an ICU (Intensive Care Unit) for monitoring, and the nurse would perform some or all of these emergency actions:
1. Bowel rest and nasogastric suction,
2. Serial abdominal examinations,
3. Providing intravenous fluids, blood, and platelet transfusions when needed,
4. Using antibiotics to fight the infection, and obtaining cultures to determine if the antibiotic is working,
5. Not administering medication that could worsen the situation.
