Answer:
Option (c).
Explanation:
Cellulose is one of the most important carbohydrate of the plant that provide structural framework to the plant cells. Cellulose is made of the monomer of the glucose that are linked through the beta glycosidic linkages.
Although cellulose contains large number of glucose but it cannot be used as the nutrient source for humans. Humans and other vertebrates lacks the enzyme cellulase that is required for the digestion of cellulose. Cellulose cannot be broken down in the human body.
Thus, the correct answer is option (c).
5f− inner transition series of elements are placed separately at the bottom of the periodic table. Reason: (i) This prevents the undue expansion of the periodic table i.e., maintains its structure. (ii) This preserves the principle of classification by keeping elements with similar properties in a single column.
<h3>What is the difference between transition and inner transition elements?</h3>
The main difference between transition metals and inner transition metals is that transition metal atoms have their valence electrons in the outermost d orbital whereas inner transition metal atoms have their valence electrons in the f orbital of the inner penultimate electron shell.
<h3>How many inner transition elements are there?</h3>
Total number of inner transition elements in periodic table is 28, 14 each in lanthanoid and actinioid series.

Answer is D. Beaker can ONLY provide approximate volume of a liquid.
Answer B is incorrect. Graduated cylinder provides an accurate volume of a liquid, not a beaker.
