Cellulose is a straight chain polysaccharide which is made up of glucose molecules that are joined together by beta 1,4 glycosidic bonds. Cellulose is the principal structural material of plants and plants use it to build strong structures. For instances, the rigid cell wall of plant cells is made up of cellulose.
Thus, the correct option is D.
Answer:
The correct answer would be - 1. group 2.period 3. less 4. more
Explanation:
elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.
At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.
Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.
As most responsive metals are put on the left half of occasional table.
Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.
Answer: It's not observable, but is determined based on a large amount of
related evidence.
