Q.25. How is sex of a child determined ?
The responsibility of the birth of a girl child is often pinned on the mother. But this is not true. The female cell has X-chromosomes while the male spermcell has XY chromosomes. The female egg cell divides resulting in two cells having single X-chromosome each. When the sperm cell divides, half the cell receives the chromosomes while the other half receives the Ychromosomes. An egg cell fertilized by the sperm cell having X-chromosomes will develop into a girl child. On the other hand if the sperm cell containing Y-chromosomes fertilizes the egg cell, it will develop into a boy.

Q.26. What are the functions and sources of riboflavin ?
It is essential for the enzyme that helps in the metabolism of carbohydrates, proteins and fats. It unites with the enzymes that help cells to use O2.

Riboflavin is known to promote the general well being among individuals.

It is needed to prevent ocular lesions (wounds and dryness around eyes).

It is needed to check seborrhea of skin (rash and dryness).

Riboflavin also checks cracking of lips and tongue.
Sources of Riboflavin
Cereals lack in riboflavin. Fruits, roots and vegetables are also poor sources of this vitamin. Fats and oils are totally devoid of this vitamin. The richest source is yeast.

Meat, specially liver, milk, green vegetables and grain have fair amount of this vitamin. Liver contains approximately sixteen times more riboflavin than present in the ame quantity of milk. Milk should be covered to reduce the loss of riboftlavin. This vitamin is lost if the food is cooked in large quantity of water.

Q.27. What is food spoilage ? Define microbial and enzymatic spoilage.
Food is considered spoilt when it has undergone undesirable changes in its natural (i) Colour (ii) Flavour (iii) Odour (iv) Appearance (v) Texture (vi) Consistency (vii) Shape and (viii) Nutritive value.
Every food that we eat is biological in origin.
Vegetables and fruits are still alive when purchased, but meat starts undergoing chemical changes soon after slaughter. The food that you eat should be wholesome and health promoting. Remember food spoilage is a natural phenomenon occurring at varying rates depending upon harvesting, storing, handling and processing factors.
Microbial and Enzymatic Spoilage : Some microorganisms are naturally present in food while some more find entry into food during harvesting, transportation, storage, handling and cooking. Can you name these microorganisms? Yes – Bacteria, yeast, moulds and fungi. Some amount of enzymes are also produced during microbial activity. Some bacteria grow faster than others. The fast growing bacteria will soon dominate the food. Most bacteria take minutes to a couple of hours to adapt to new environmental conditions. Hence you must decide either to cool or heat or consume food within four hours of its purchase.

Enzymes are an intrinsic part of foods. Enzymes bring about desirable changes in colour, taste, flavour and texture of food. Ripening of green tomatoes/ mangoes is brought about by the action of enzymes.
Further continuation of enzymatic actively results in over-ripening and rotting of food. The desirable changes brought about in food by enzymes are called ‘positive’ while rotting etc. are ‘negative’.

 Q.30. What should be the nutritional requirements of a diarrhoea patient ?
Maintaining nutritional status is a big problem in diarrhoea. Considerable loss of energy, liquids, minerals, serum, protein etc. is caused in it. Hence, all these things plays vital role in diet therapy of this disease.
Energy : Consider able loss of energy deman ds sufficient intake of calories. To meet the calorie requirements” easily digestible carbohydrate rich foods like fruit juices, suji kheer, boiled rice etc. should be given to the patient.
Proteins : Proteins are lost in considerable amount in diarrhoea. Unavailability of sufficient amount of food proteins in the body leads to, firstly disintegration of tissue proteins and then use of blood protein. It causes acute deficiency of proteins in the body. Hence, sufficient amount of proteins are required by the patient suffering from diarrhoea. Protein rich foods should be given to the patient with the improvement in his condition like boiled eggs, toned milk etc.
Fats : Fats and fat rich foods are restricted to a patient because the, intestines are incapable of absorbing them. Butter and light fats, like, cream, can be given to the patient with the improvement in his condition.
Vitamins. Deficiency of water soluble vitamins in the body is caused by the loss of water in diarrhoea (like Bcomplex and Vitamin C). Hence, fruit juices must be added in the diet of the patient.
Minerals : Loss of sodium and potassium leads to their deficiency diseases, like loss of appetite, vomiting, restlessness, loss of flexibility in the muscles of alimentary canal etc. Their deficiency can be made up by giving fruit juices to the patient after adding salt.
Water : Lot of water is excreted out in diarrhoea. Hence, it is very important to make up for this deficiency. Patients should be given liquids in the form of mineral water, juices, soups, lemon water, barley, water etc. Oral dehydration Solution (ORS) should be given to prevent dehydration.

Q.31. What is the importance of proportion in clothing ?
. According to this principle, different parts of the dress should be in proper proportion.
Button, yoke, collar, cuff, pockets etc. should, be in proportion to the size of the dress. A large pocket or big size buttons if appended on a small frock would look odd because they are not in right proportion to the frock. Small pocket and buttons would look more appropriate on a small frock.
The golden rule in any form of art is to decide in unequal parts than dividing in equal parts. This looks more attractive and interesting. Salwar-kamij dividing the body in two equal parts would not appeal much. Similarly, the equal length of skirt and top is also not desirable. In frock the length of yoke and skirt should be in right
The dress should be in proportion to the size of the person. Body structure of people differ from one another.
In the construction of clothes, harmony should be created with the size of the body. Large collars, cuffs and pockets in a dress will not suit a tall and heavy woman rather these would suit a slender woman. Principle of proportion should be kept in mind while choosing a print. Small prints go well with fat and short women, while large prints with lean and thin women.
Different colours used in dress should be in right proportions. Light colours should be used in the longer portion and dark colour in the smaller. portion of a dress.
A dark colour blouse looks good with a light colour sari of the same colour. But light colour blouse does not look good with a dark colour sari.
