1. An experiment to study osmoregulation in human was carried out by relating the

volume of water intake to the volume of urine produced. Four groups of students

which are group P, group , group ! and group " were given different volume ofplain water to drink. After one hour, each student in the groups urinated and collected

their urine in a measuring cylinder.

#he volume of urine produced is recorded in #able 1.

Satu eksperimen untuk mengkaji pengosmokawalaturan dalam manusia telah

dijalankan dengan mengaitkan isipadu air yang diminum dengan isipadu air kencing

yang dihasilkan. Empat kumpulan pelajar iaitu kumpulan P, kumpulan , kumpulan !

dan kumpulan "telah diberi air kosong yang berbeza isipadu untuk diminum. Selepas

satu jam, setiap pelajar dalam kumpulan membuang air kecil dan mengumpulkan air

kencing mereka di dalam silinder penyukat.Isipadu air kencing yang dihasilkan direkodkan dalam Jadual 1.
