Prokaryotes are cells without a distinct nucleus.They have genetic material but that material is not enclosed within a membrane. Prokaryotes include bacteria and cyanophytes. The genetic material is a single circular DNA strand and is located within the cytoplasm.
Healthcare providers consider a normal blood pressure reading to be 120/80 or below. However, normal blood pressure can actually fall anywhere in a range from 90/60 to 120/80 -- it's not just one set number. The top number of the blood pressure reading is called the systolic pressure.
Hypotension is the medical term for low blood pressure (less than 90/60). Normal blood pressure is usually in the range of 120/80 (systolic/diastolic). In healthy people, especially athletes, low blood pressure is a sign of good cardiovascular (heart and blood vessel) health.ypotension is the medical term for low blood pressure (less than 90/60).
