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.
2. Blood pressure and heart rate have ânormalâ target numbers. False: There are guidelines, but whatâs normal varies from person to person. Optimal blood pressure typically is defined as 120 mm Hg systolic â which is the pressure as your heart beats â over 80 mm Hg diastolic â which is the pressure as your heart relaxes. For your resting heart rate, the target is between 60 and 100 beats per minute (bpm).
