Choose the correct answer from the options given below:

Correct Answer: (b) B, C, A, D, E
Solution:

F Test formula is used to determine whether discrepancies between two groups of data are meaningfully different. To assess whether the mean of two populations is statistically significant, it is frequently employed in research investigation.
The correct sequence of steps of F calculation are:
• Arrange the raw data in tabular form
• Calculate Row totals and column totals
• Square each row total
• Compute Mean values for columns
• Square each raw score and calculate squared column totals and grand totals

38. Celluloses and hemicelluloses, in the text of food science and human nutrition are-

A. Supporting structures in plant tissues
B. Relatively resistant to breakdown
C. Soluble in cold water
D. Not digested by humans
E. Yield considerable energy
Choose the correct answer from the options given below:

Correct Answer: (a) A, B, D only
Solution:

Cellulose and hemicelluloses are two polysaccharides that serve as structural component of plant cell wall.
Cellulose and hemicelluloses are crystalline in nature and hence resistant to breakdown.
Cellulose and hemicelluloses both contain beta linkage and humans lack enzyme to breakdown β-linkage hence they cannot be digested by humans.
