The population of our country has already crossed 120 crores. The population was 680 million in 1981. This unprecedented growth of population is generally referred to as ‘Population Explosion’. India is supporting 16 percent of world’s total population on 2.4% of the world’s land area.

It gives foul smell in mouth and the condition is called “gingivitis”.Deficiency of vitamin C interferes with the synthesis of collagen and clotting of blood. There are hemorrhages under the skin. These can be seen as dark patches known as “patechial hemorrhages .”
Horny follicular keratosis similar to that in vitamin A deficiency is present in scurvy patients.
The infants suffering from “infantile scurvy” are restless and do not sleep well. They have painful and swollen thighs. The children often keep their legs bent like ‘frog legs’ because of pain.
ICMR (Indian Council of Medical Research) recommends 40 mg. of ascorbic acid for adult man and woman.

Infants from 6 months onwards need 25 mg and older children will do well with an allowance of 40 mg/day.

Q.30. Write a short notes on floor decoration in India.
Ans.
Decoration and beautification of floor is done during festivals and other special occasions. This is an art which can be learnt effortlessly while participating in the family festivals.
Floor decoration is known by different names in the various states. i.e. ‘Rangoli’ in Maharashtra, ‘Kolam’ in Tamil Nadu, ‘Alpana in Bengal, ‘Sathiya’ in Gujarat, ‘Moggulu’ in Andhra Pradesh; “Sanjhi” in Uttar Pradesh and ‘Mandanas’ in Rajasthan. The materials and the techniques vary from region to region. The designs are simple and the materials can be most inexpensive. Hence almost anybody can practise and derive pleasure by beautifying the entry to their house.
The design consists of natural forms artistically done.
There is always a certain element of rustic and ritualistic appeal. The materials used include flowers, rice powder, colours, sawdust, and chalk powder. Haldi, roli (kumkum) and mehendi are used to make the traditional rangoli at the marriage ‘mandap’. Rice paste is used for making freehand floor decoration at the entry to the ‘puja house’.
Flower petals produce attractive rangoli at hardly any cost. In fact finely cut grass or ‘thuja’ leaves make a beautiful background for the floral rangoli. During Deepawali and Ganesh Chaturthi people decorate their homes with designs created out of grains. These grains should be put to use in the home afterwards. The grains can be substituted by coloured marble chips of varying sizes and colours. Rice powder or flour is filled in hollow and perforated wooden or metal pipes. These are then rolled on slightly moist floor to give interesting border designs. Tribals apply fresh mud or cowdung paste to clean the walls and floor before making the design.
According to them the wall designs provide peace to ghosts and spirits, thus leaving the home to the happy family. ‘Sanjhi’ designs are intricate and many colours are used to create these beautiful patterns during Janmashtmi. Sawdust coloured in earthy colours is used to make beautiful carpet designs.

Gigantism is the result of its over secretion and dwarfism due to its reduced secretion of hormones. It also controls the activity of other glands.
(ii) Thyroid : This gland controls the metabolic process of our body. If the secretion of hormone from this gland is more, it leads to increase in pulse rate and loss of weight. Deficiency of its secretion leads to reduction of pulse rate, overweight, less ossification of bones and hair loss.
Deficiency of Iodine leads to disturbance in the functioning of thyroid glands etc.
(iii) Parathyroids : Th e deficiency of h ormone secreted by this gland leads to reduction in calcium content in the blood and-increase of phosphorus. This leads to frequent fractures and stone formation in blood.
(iv) Thymus : Its function is limited to early growth and development because it vanishes after puberty. It is mostly associated with the development of sex characteristics.
(v) Adrenal : This gland has a powerful effect on blood circulation. Its hormone (Adrenalin) increases the heart rate and blood output. Its hormone increases BP., increases, muscular power and delays fatigue. Therefore, adrenal glands play an important role in emotions and exercise.
(vi) Pancreas : Secretion of Insulin by the inner portion of this gland helps in the burning of sugar in our body. Lack of insulin leads to diabetes, i.e., the increase of sugar level in the blood. Diabetes is a slow killer disease.
