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.
High Blood Pressure - The pressure or tension exerted by the blood on the arteries and the venous blood vessels is called blood pressure. Normal blood pressure is less than 120/80 mmHg, where 120 is the systolic blood pressure (SBP) and 80 is the diastolic blood pressure (DBP). High blood pressure occurs when the blood is pumped by the heart through the system that is abnormally fast and powerful.
