Answer:
is the higher number of a blood pressure reading.
Explanation: systolic blood pressure is the higher number of a blood pressure reading and its measure in millimeter of mercury.
Systolic pressure is the amount of pressure in the arteries when contraction takes place in heart. Diastolic pressure is the pressure the heart when it relaxes. It is the lower number of blood pressure reading
When the systolic pressure is >120mm Hg and diastolic is less than 80mm Hg it is normal
120-129mm Hg and diastolic less than 80mm Hg it high and such person needs a regular medical check up
But when systolic 129-139 mmHg
and diastolic is 90mm Hg or above it means the individual is having hypertension stage 1
Above 140mm Hg is hypertension stage 2 and it is the most severe stage. It means the person is hypertensive and medical attention needs to be seek for necessary treatment as this could lead to death of such individual if not well managed.
DNA can illustrate that evolution has occurred since in the process of natural selection advantegeous genes or traits have been selected to pass on through generations and further more evolve as long as the species survies and is successful in reproducing.
