(a) The following is a newspaper clipping about illegal logging in Malaysia

PUTRAJAYA August 30 - The government will enforce the law to impose amandatory jail sentence of one year or a maximum of 20 years without a

compound of the offenders involved in illegal logging .

Firm decision was made at the Meeting of the National Forestry Council

(NCC ) 19th chaired by Deputy Prime Minister Datuk Seri Najib Tun Razak

here today.

Accordingly, the Attorney General will conduct a study and research about

which is expected to take about six months to ensure that law enforcement

can be carried out immediately due.

Najib firm , the decision was taken in view of the compound which has no

effect on fighting illegal logging even involve the millions of dollars .In addition

to the loss of millions of dollars , illegal logging has affected the well-being of

people with problems involving the environment , air and water .

Illegal logging is still going on in this country is done by the same group , but

this did little syndicate numbers. So now MPN agree that we do not use the

compound ( to deal with ) but continued to be charged in court , '' he said. He

was speaking at a press conference after chairing the meeting at PerdanaPutra Building here today.

Meetings involving all the Chief Minister and the Chief Minister was also

attended by the Minister of Natural Resources and Environment Minister

Datuk Seri Adenan Satem .

According to Najib , the results were much better because it involves action

against offenders prison more restrictive than the existing enforcement .He

added that a prison sentence will be carried out in accordance with the

provisions of a special law that would be formed under the National Forestry

Act 1984

( Amendment 1993 ) .

[10 marks]

[10 markah]

PUTRAJAYA 30 Ogos - Kerajaan akan menguat kuasa undang-undang untuk

mengenakan hukuman penjara mandatori setahun atau maksimum 20 tahun

tanpa dikenakan kompaun bagi pesalah terlibat dalam aktiviti pembalakan

haram.

Keputusan tegas itu dicapai pada Mesyuarat Majlis Perhutanan Negara (MPN)

ke-19 dipengerusikan Timbalan Perdana Menteri, Datuk Seri Najib Tun Razak di

sini hari ini.

Sehubungan itu, Peguam Negara akan membuat kajian dan penelitian

mengenainya yang dijangka mengambil masa kira-kira enam bulan untuk

memastikan penguatkuasaan undang-undang itu dapat dijalankan serta-merta

kelak.

Tegas Najib, keputusan itu diambil memandangkan tindakan kompaun yang

selama ini tidak mendatangkan kesan bagi membanteras pembalakan haram

walaupun melibatkan nilai berjuta-juta ringgit.

Selain kerugian berjuta-juta ringgit, kegiatan pembalakan haram turut

menjejaskan kesejahteraan rakyat dengan melibatkan masalah terhadap alam

sekitar, udara dan air.

Pembalakan haram di negara ini masih berterusan yang dilakukan oleh

kumpulan yang sama tetapi sindiket ini tidak banyak jumlahnya. Jadi sekarang iniMPN bersetuju bahawa kita tidak guna kompaun (untuk menanganinya) tetapi

terus didakwa di mahkamah,'' kata beliau. Najib berkata demikian pada sidang

akhbar selepas mempengerusikan mesyuarat itu di Bangunan Perdana Putra di

sini hari ini.

Mesyuarat yang melibatkan semua Menteri Besar dan Ketua Menteri itu turut

dihadiri Menteri Sumber Asli dan Alam Sekitar, Datuk Seri Adenan Satem.

Menurut Najib, keputusan itu jauh lebih baik kerana melibatkan tindakan penjara

terhadap pesalah yang lebih tegas berbanding penguatkuasaan yang ada

sekarang.Tambah beliau, hukuman penjara akan dilaksanakan mengikut

peruntukan undang-undang khas yang akan dibentuk di bawah Akta Perhutanan

Negara 1984.

(Pindaan 1993).

1 When plant cells are immersed in different concentration of solution, there will be changes

in the mass, length or the texture due to a process named osmosis.

Apabila sel tumbuhan direndam dalam larutan yang berbeza-beza kepekatannya, akan

terdapat perubahan jisim,panjang dan tekstur tumbuhan tersebut yang disebabkan oleh

satu proses yang dinamakan osmosis.

A group of students carried out an experiment to investigate the effect of different

concentration of sucrose solutions on the mass of potato slices.

Four slices of potato with the same initial mass is obtained.

Each slice of potato is then immersed in distilled water (0 M), sucrose solution 0.2M,

sucrose solution 0.4M, and sucrose solution 0.6M.

After 20 minutes of immersion, each potato slice is taken out, wiped and weighed again.

Sekumpulan pelajar menjalankan satu eksperimen untuk menyiasat kesan kepekatan

larutan sukrosa yang berbeza-beza terhadap jisim kepingan ubi kentang.

Empat keping kepingan ubi kentang dengan jisim awal yang sama telah disediakan.

Setiap kepingan ubi kentang kemudian direndam di dalam air suling (0M),larutan sukrosa

0.2M, larutan sukrosa 0.4M dan larutan sukrosa 0.6M.

Selepas direndam selama 20 minit, setiap kepingan ubi kentang dikeluarkan, dilap dan

ditimbang semula.

2 Transpiration is the loss of water vapour through evaporation from the surface of theplants. This loss of water is replaced by the absorption of water from soil by the plantroots. Light intensity is one of the factors that affect the rate of transpiration.

Transpirasi adalah kehilangan wap air melalui penyejatan daripada permukaan

tumbuhan. Kehilangan air ini digantikan oleh penyerapan air dari tanah oleh akartumbuhan. Keamatan cahaya ialah salah satu daripada faktor-faktor yangmempengaruhi kadar transpirasi.

Based on the above information, design a laboratory experiment to study the effect oflight intensity on the rate of transpiration of a plant.The planning of your experiment must include the following aspects:
