41. In the nutrition management of chronic renal failure, following are restricted in the diet

(1) Protein
(2) Sodium
(3) Carbohydrate
(4) Water
(5) Energy
Choose the correct option :

(a) (1), (2), (4)
(b) (1), (2), (3)
(c) (2), (3), (5)
(d) (1), (3), (5)

Correct Answer: (a) (1), (2), (4)

Solution:

Chromic renal failure is a state of progressive loss of kidney function where the glomerular filtration rate falls rapidly. In chronic renal failure protein, sodium and water is restricted.

42. Following are the functions of protein in human body :

(1) Growth and maintenance of tissues
(2) Promoter growth of desirable bacteria
(3) Acts as an insulator
(4) Maintenance of appropriate pH
(5) Transportation of nutrients
Select the correct option :

(a) (1), (2), (4)
(b) (1), (3), (d)
(c) (1), (3), (5)
(d) (1), (4), (5)

Correct Answer: (d) (1), (4), (5)

Solution:

The term protein meaning "to take first" protein is a nitrogen containing constituent of food. About 50% of protein is present in muscle, 20 percent in bone, 10 percent in skin and rest is present in other parts of the body.
Functions of protein-
• Growth and maintenance of tissue.
• Maintenance of appropriate pH.
• Transportation of nutrient.

43. Following foods are cooked by the method of broiling :

(1) Papad
(2) Sweet potato
(3) Flaky pastry
(4) Chappaties
(5) Apple pie
Select the correct option :

(a) (1), (2), (3)
(b) (1), (2), (4)
(c) (2), (3), (4)
(d) (2), (3), (5)

Correct Answer: (b) (1), (2), (4)

Solution:

Broiling is also called grilling. Grilling consists of placing the food below or above or in between red hot surface when food is kept under the heater, it is heated by radiation only. This result in browning of foods. If the food is above the heater, heat is transmitted to the food through convection currents as well as radiation with increased efficiency.
Foods that are cooked by the method of broiling are:-
Papad
Sweet Potato
Chappaties

44. Which of the following factors inhibit calcium absorption ?

(1) Oxalic acid
(2) Protein
(3) Caffeine
(4) Phytic acid
(5) Lactose
Select the correct option :

(a) (1), (2), (3)
(b) (1), (2), (4)
(c) (1), (3), (4)
(d) (1), (3), (5)

Correct Answer: (c) (1), (3), (4)

Solution:

Factors inhibit calcium absorption-
(a) Oxalic Acid : Oxalic acid combines with calcium to form insoluble complex of calcium oxalate which can not be absorbed.
(b) Phytic Acid : Phytic acid is present in whole grain, red legumes are some nuts which can decrease the absorption of calcium.
(c) Caffein : High intakes of caffein affect the bioavailability of calcium in urine an stimulating the secretion of calcium into the gastrointestinal tract.

45. Enzymatic browning in cut fruits and vegetable can be prevented by :

(1) Blanching
(2) Increasing pH
(3) Use of antioxidants
(4) Dipping in water
(5) Leaving exposed to air
Select the correct option :

(a) (1), (2), (3)
(b) (1), (2), (4)
(c) (1), (3), (4)
(d) (1), (3), (5)

Correct Answer: (c) (1), (3), (4)

Solution:

Enzymatic browning occur when the cut fruits and vegetables are exposed to oxygen and rapid darkening of cut surface take place. It can be perverted by blanching, use of antioxidant, dipping in water, lowering the pH to 4.0 inhibits the phenolase activity and prevention of cut fruits and vegetables from oxygen.

46. Essentials of clothing for infants are :

(1) Variety
(2) Comfort
(3) Style
(4) Hygiene
(5) Warmth
Choose the correct option :

(a) (2), (3), (5)
(b) (1), (3), (5)
(c) (2), (4), (5)
(d) (1), (2), (3)

Correct Answer: (c) (2), (4), (5)

Solution:

The essentials of clothing for infants are:-
• comfort
• Hygiene
• Warmth

47. Following are the physical properties of silk :

(1) Smooth fibre
(2) Moderate elongation
(3) High density
(4) Low moisture regain
Choose the correct option :

(a) (1) and (2)
(b) (2) and (3)
(c) (3) and (4)
(d) (1) and (4)

Correct Answer: (a) (1) and (2)

Solution:

Physical properties of silk filament are–
• Smooth fibre
• Moderate elongation
• Tenacity
• Breaking load
• Size
• Colour and lusture

48. ...arded yarn is :

(1) Coarse
(2) Smooth
(3) Less durable
(4) More durable
(5) Fine
Choose the correct option :

(a) (2) and (3)
(b) (2) and (4)
(c) (1) and (3)
(d) (4) and (5)

Correct Answer: (c) (1) and (3)

Solution:

Carded yarn are basically cotton made and they are not counseled so they posses rough and coarse surface and are less durable.

49. gathering effect will be best on :

(1) malmal
(2) taffeta
(3) chiffon
(4) linen
Choose the correct option from above :

(b) (1) and (3)
(a) (1) and (2)
(c) (3) and (4)
(d) (2) and (4)

Correct Answer: (b) (1) and (3)

Solution:

Gathering is a sewing technique for shortening the length of a strip of fabric so that the longer piece can be attached to a shorter piece. It is mainly use to provide fullness to the fabric. Gathering effect will be best on light weight fabric.
