Mengel and Kirkby  have proposed that the essential elements be classified instead according to their biochemical role and physiological function, It shows such a classification, in which plant nutrients have been divided into some basic groups these are;

a.) The first group is nutrients that are part of carbon compounds

b.) The second group is important in energy storage reactions or in maintaining structural integrity

c.) The third group has important roles in reactions involving electron transfer or redox reaction

d.) The fourth group is present in plant tissue as either free ions or ions bound

Choose correct statement about Electrocardiogram Augmented Limb Leads.

a. In this type of limb lead system, two of the limbs are connected through the positive terminal of the electrocardiograph, and the third limb is connected to the negative terminal. 

b. In this type of limb lead system, two of the limbs are connected through the negative terminal of the electrocardiograph, and the third limb is connected to the positive terminal. 

c. When the positive terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.

d. When the negative terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
