As the small arteriole

entering the glomerulus is larger than the one leaving it so that a high blood pressure is build up inside the glomerulus. This pressure forces water and dissolved substances

تر

When the kidneys are removed, first, there is an immediate rise in blood urea. This indicates that urea is no longer being excreted by the kidneys but is still being made by the liver.

.... After removal of the liver the curve remains more or less, steady. This indicates the urea is nei- ther being made or excreted.

Graph 3:

When the liver and kid- neys are removed, the con- centration of the blood urea remains steady. As seen in graph 1 and 2, this. indicates the urea is nei- ther being made or excreted.

Graph 4:

When only the liver is removed, blood urea falls as it is excreted by the kidneys.

c)i) Filamentous habitat:

Increases the gaseous. exchange surface; helps. to resist water flow; en- ables more efficient light capture in the somewhat diffuse lighting condition under water.

ii) Poorly developed root

system:

Water and salts are absorbed over the whole surface of the plant, and. not only by the roots; plant is also supported by buoyancy.

iii) thi cuticle.

PHOTOGRAPH B

The photograph shows a temporary lagoon at Tap Shek Kok in the Castle Peuk Area. It is a sheet of salt water separated from the open sea by sand banks..

The lagoon is formed by the Landward extension of a apit when the waves attack the bay at an oblique angle The swash and backwash will cause material to be moved along the coast. This save- ment is called longshore drift. A sudden change in the direc tion of the coastline does not affect its course, and the material being carried will then, be deposited in slack water to form a spit(FIG, 1IA). The outer end of the spit may curve landward because of wave refraction and eventually join the coast. The narrow stretch of water thất it encloses is known as, (FIG.

PHOTOGRAPH A

The features shown on. the photograph are vertical cliff and stack..

This photograph' is taken.

The from Orkney, England. region is made of well-bedded anada tones, with vertical faults. (FIG. 1A). As a result of marine erosion, vertical cliffs and a tack are formed.

Being a headland, it is attacked by waves armed with rock from all directions. Wave erosion concentrates along the vertical faults, which is the weakest zones of the region, caves are form- ed on both sides (FIG. 1B). When two sea-caves on opposite. sides of the beadland unite, a natural arch is formed (FIG. 1C). With prolonged wave erosion, accompanied by other, forms of erosion on the upper parts, the roof of the March finally collapses. The end of the headland is then. isolated and fretted into a rocky pinnacle which is usually termed a stack. (F16)

The population pattern of Hong Kong has undergone sig- nificant changes in the last decade. Both rural-urban. migration and decentralization · have contributed greatly to the changes. AREAS OF DECREASED POPULATION

Several of the areas recorded a decrease, they are: 1) North Saikung

Amongst the areas of de-.. creased population, North Sai Kung recorded the highest rate. This district is on the extreme east of the Colony, and is not connected by major transportation lines to the urban area. The lief is hilly, soil fertility has been highly deprived as ex- posed to strong winds and heavy rainfall. Villages are small. Many of the villagers have abandoned the land to seek their living in the urbanized areas of Hong Kong or even foreign countria.

2) Shu Tau Kok and Tai u

Sha Tau Kok in the extreme north of the New • Territories and Tai 0 on the western coast of Lantau Island have the second highest rate of decrease. Sha Tau Kok, which is situated on the bord- er between the N.T. and China, has been delimited is a res- tricted area and has not been benefited from tourism. Tai O is a fishing village and is linked with the city centre by ferry, Both of them are too far away from the urban centre and have therefore suffered from the inconveni- ance of transportation.

3) Uther areas in the N.T.

Other areas such as Tung Chung, Cheung Chau, and S. Lamma, each of them recorded - a alight decrease,

is mainly a result of rural-

urban migration. The decrease

increases with increasing dis- tance from the city centre.

Some of the people go abroad

4) Hong Kong Is. and Kowloon

but a great majority of them move the newly established satellite towns.

Hoth Hong Kong Island and Kowloon, which are regarded as the centre of the city, have recorde a dadrease in popula- tion. It is mainly a result of decantralization, To release the population pressure of the developed urbanized areas and make room for com- mercial activities, satellite towns are set up. Thus the people move out from the urban centre to the newly developed regions in the out- skirts. It is expecially true for the C.B.D., the rate of decrease is more than 100%. In other residential-commercial districts, such as Mong Kok, they have the same experience. Within these districts, the upper floor of building meant for residential purposes are being increasingly used for offices.

AREAS OF INCREASED POPULATION

Most of the census dis- tricta recorded an increase in their population during 1961-1971.

1) Tsuen Wan and Tuen Mun Amongst the areas of increased population, Tsuen Wan and Tuen Mun recorded the highest rates. The opening up of these two areas to

other parts of Hong Kong such

as Sha Tau Kok. The cons truc-

tion of government low-cost

housing estates has been an encouraging factor, too.

2) Ping Shan and Sheung Shui

Some areas in the New Territories, where transpor- tation is easy, also recorded sharp to moderate increase, -such as Ping Shan, a rural

centre on the Yuen Long Plain and Sheung Shui. These areas.

of more convenient transporta- tion have attracted many rural settlers from the remote

places. Besides, Yuen Long

and Sheung Shui are also under the government development schemes.

3) Urbanized areas

Some areas near the urban centre, such as Ngau Tau Kok and Aberdeen had experienced increase too. It is also a result of decentralization. They are as trial regions with large number of govern- ment low-cost housing units,
