Soalan 1 / Question 1

Saiz populasi merujuk kepada bilangan organisma yang terdapat dalam sesuatu habitat. Saiz

populasi boleh dihitung dengan kaedah perhitungan terus, namun kurang praktikal disebabkan

saiz ekosistem, bilangan organisma yang terlibat serta mobiliti organisma. Oleh itu, cara yang

lebih praktikal ialah dengan menggunakan satu sampel (bilangan kecil) organisma dalam sesuatu

ekosistem.

Sekumpulan pelajar ingin mengkaji kesan faktor kelembapan dan keamatan cahaya ke atas saiz

populasi siput Achatina fulica di kawasan sekolah. Bagi tujuan tersebut, dua kawasan telah

dipilih dan kaedah yang digunakan ialah kaedah tangkap, tanda, lepas dan tangkap semula.

Kawasan A adalah merupakan kebun sains sekolah manakala kawasan B adalah padang

sekolah. Kawasan kajian telah ditandakan dengan menggunakan tali, meliputi 2 m x 2 m.

Population size is referred to the number of organism lives in a habitat. Population size can be

calculated by direct counting method, but less practical due to the size of ecosystem, the number

of organism involved and the mobility of the organisms.

A group of students want to study the effect of humidity and light intensity factor to the size of

population of snails Achatina fulica at the school area. For that purpose, two areas have been

chosen and the method captures, mark, release and recapture is used. Area A is school science

garden area while Area B is school field. The studied area is marked with string, covering 2m x

2m area.

Doh / dough Roti / bread

2. Industri pembuatan roti sememangnya bukan satu perkara baru dalam industri makanan di

negara kita. Pelbagai jenis roti dapat dihasilkan dengan menggunakan kaedah pembuatan roti

yang betul. Kehadiran yis yang berespirasi secara anaerobik dan membebaskan karbon dioksida

menyebabkan doh mengembang.

Bread making industry is not new in the food industry in our country. Various types of bread can

be produced by using the correct method of bread making. The presence of yeast in anaerobic

respiration, release carbon dioxide allows the dough to expand.

Berdasarkan maklumat di atas, rancang satu eksperimen dalam makmal untuk mengkaji kesan

kehadiran yis dalam pembuatan roti.

Based on the above information, plan a laboratory experiment to study the effect of the presence

of yeast in bread making.
