Change may refer to transformation or alteration of form which could take place in organisms, humans, animals and various other substances. The type of transformation which organisms or materials undergo is used in classifying change in to either of chemical, physical, biological and so on. Physical change usually has to do changes in size and form without any alteration on the chemical identity of an element. However, chemical changes has to do with chemical reactions which leads to the formation of new products, As a result, chemical changes are usually not reversible.

Explanation:
Answer:
Glycine will be better
Explanation:
Some of the characteristics of good buffer solution are-
a) Must be highly soluble
b) Non toxis
c) Must have pka values ranging between 6.0 to 8.0
d) Low absorbance rate, permeability and reactivity
Based on the above description, we know that the first pka value of glycines is 2.34 and second pk value of 9.60 while the same for phosphate is 2.16 and 7.21 and bicarbonates is 6.4.
Also, glycine is less permeable as compared to carbonates and bi carbonates.
