Paleozoic.
Era immediately follows Precambrian It lasted about 4.5 billion years.
When did abundant fossil evidence first appear in the geologic record.
540 million years ago.
<span>Food molecules like lipids, proteins and polysaccharides are broken down enzymatically via digestion process, which occurs in our intestine cells (digestive system). Those large polymeric molecules are broken down into their monomer subunits—proteins into amino acids, polysaccharides into sugars, and fats into fatty acids and glycerol. Formed small organic molecules are now ready for the oxidation (a process that produces ATP and consumes O2) which occurs partly in the cytosol and in the mitochondrion. Oxidation processes include glycolysis and citric acid cycle which are differently required in different tissues. Nervous system (nerve cells) rely almost entirely on a constant supply of <span>glucose<span> from the bloodstream. In contrast, liver cells supply glucose to actively contracting muscle system which needs a lot of ATP energy.</span></span></span>
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.
