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.

USPshnik [31]

Answer:

Stage 2 hypertension

Explanation:

Hypertension is a body circulatory system condition whereby the pressure of the blood vessels are raised persistently. The heart pumps blood to the different organs of the body through the blood vessels, each time it beats

The normal blood pressure in the vessel = 90/60 mmHg to 120/80 mmHg

The blood pressure of a prehypertension person or person at risk of having hypertension = 120-139/80-89 mmHg

The blood pressure at Stage 1 hypertension = 140/90-99 mmHg

The blood pressure at Stage 2 hypertension = 160/100 mmHg.
