The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
Red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.
<h3>
What are proteins?</h3>
The term "protein" refers to a macro- and large-scale biomolecule that has one or more lengthy chains of amino acid residues. An amino acid chain makes up the basic building block of proteins.
When oxygen binds to the heme portion of the hemoglobin molecule in red blood cells during physiological respiration, oxyhemoglobin is created. This procedure takes place in the pulmonary capillaries close to the lung's alveoli.
Thus, red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.
