(c) Narrowed blood vessels leave a smaller opening for blood to flow through.
Having narrowed blood vessels is like turning on a garden hose and holding your thumb
over the opening. The smaller opening makes the water shoot out with more pressure.
In the same way, narrowed blood vessels lead to high blood pressure. Other factors,
such as kidney problems and being overweight, also can lead to high blood pressure.
Salur darah yang sempit akan meninggalkan ruangan yang lebih kecil untuk
darah mengalir. Salur darah sempit ini seolah-olah seperti membuka hos air di kebun
dan menekan ibu jari pada hujung hos tersebut. Bukaan yang kecil pada hos
menyebabkan air terpancut dengan lebih tekanan. Pada masa yang sama, salur darah
yang sempit akan menyebabkan penyakit tekanan darah tinggi. Faktor lain seperti
masalah buah pinggang akibat diabetes dan kegendutan juga boleh membawa kepada
tekanan darah tinggi.

Studies show that one in four wells in the U.S. will test positive for coliform bacteria. This
alarming statistic underscores the importance of proper disinfection and accurate,
periodic water testing. Ultraviolet (UV) light has been used since the early 20th century
to disinfect water, but increased consumer awareness about waterborne pathogens has
led to a rising demand for UV systems in private homes.
Below are some of the advantages and disadvantages of residential UV systems.
Kajian menunjukkan bahawa satu dalam empat telaga di Amerika Syarikat akan
menguji positif bagi bakteria coliform. Statistik yang membimbangkan ini menekankan
pentingnya disinfeksi yang betul dan tepat, ujian air berkala. Cahaya ultraviolet (UV)
telah digunakan sejak awal abad ke-20 untuk membasmi air, tetapi peningkatan
kesedaran tentang patogen bawaan air telah membawa kepada peningkatan
permintaan bagi sistem UV di rumah-rumah persendirian. Berikut adalah kebaikan dan
keburukannya pada sistem UV di tempat kediaman.
Advantages:
Kelebihan :
Unlike other disinfection methods, such as chlorination, UV does not require the use of potentially harmful chemicals. Tidak seperti kaedah pembasmian kuman lain, seperti pengklorinan, UV tidak memerlukan penggunaan bahan kimia yang mungkin berbahaya.
Easy maintenance. If the proper pretreatment is employed — a sediment filter or
reverse osmosis system, for example — UV systems only require users to replace the
lamp once per year.
Penyelenggaraan yang mudah. Jika ada rawatan yang betul dijalankan, contohnya
penggunaan penapis sedimen atau sistem osmosis songsang, sistem UV hanya
memerlukan pengguna untuk menggantikan lampu sekali setiap tahun.
Disadvantages:
Kelemahan:
The water being treated must be adequately free of color and turbidity to allow
sufficient penetration.
Air yang dirawat mesti cukup jernih dan kekeruhan untuk membenarkan penembusan
yang mencukupi.
Areas with extremely hard water are not ideal for UV systems because scale buildup can
negatively affect the lamp’s ability to disinfect.
Kawasan air yang deras adalah tidak sesuai untuk sistem UV kerana pembentukan skala
negatif boleh menjejaskan keupayaan lampu untuk membasmi mikroorganisma.
Inadequate treatment utilizing UV lights may only damage the microorganisms, rather
than disrupt them. To ensure an effective treatment of the water, the dosage of UV
treatment has to be sufficient enough to disinfect the water.
Rawatan yang tidak cukup menggunakan lampu UV mungkin hanya merosakkan
mikroorganisma, dan bukannya menghapuskan mereka. Bagi memastikan rawatan air
yang berkesan, dos rawatan UV telah cukup mencukupi untuk membersihkan air.

(d) Water pollution occurs when water is dirtied by waste thrown into it. Polluted water is
no longer suitable for living things. Industrial wastes, chemical substances used in
agriculture and domestic waste are called water pollutants.
As a concerned student, suggest three steps that can be taken to reduce water
pollution.
Pencemaran air berlaku apabila air dikotori sampah yang dibuang ke dalamnya. Air
yang tercemar ini tidak sesuai untuk benda hidup. Sisa industri, bahan kimia yang
digunakan dalam agrikultur dan bahan buangan domestik dipanggil sebagai bahan
pencemar air.
Sebagai seorang pelajar yang prihatin, cadangkan tiga cara yang boleh diambil untuk
mengurangkan pencemaran air.
