Jambunists, some people say that Chapter 1: Introduction to Biology is not very important but read it anyway. You'll get to know the careers related to Biology and learn to write a report which will come in handy when you answer Question 2 of Paper 3. So, can you tell which careers are related to Biology? Do not get confused careers with the fields of study.Jika tidak mahir menulis lapuran Biologi, boleh rujuk Bab1. Menulis lapuran penting untuk menjawab soalan 2 Kertas 3. Berikut ialah contoh soalan 2, Kertas 3 (SBP, 2012) yang memerlukan kebolehan menulis lapuran.:
Albumen suspension is cloudy if the protein molecules are not broken down into simpler form. When an enzyme such as pepsin is added to the albumen suspension, the suspension turns clear. This shows that the hydrolysis of protein has occurred.
Ampaian albumen adalah keruh sekiranya molekul-molekul protein tidak diuraikan kepada bentuk yang lebih ringkas. Apabila satu enzim seperti pepsin dicampurkan kepada ampaian albumen, ampaian itu menjadi jernih. Ini menunjukkan hidrolisis protein telah berlaku.
By using materials and apparatus available in the laboratory, plan an experiment to investigate the effect of temperature on the rate of enzyme activity.
Your experimental planning must include the following aspects:
Dengan menggunakan bahan dan radas yang terdapat di dalam makmal, rancang satu eksperimen untuk mengkaji kesan suhu ke atas kadar aktiviti enzim.
Perancangan eksperimen anda hendaklah meliputi aspek-aspek berikut:
You'll have to know the right way to write the aim, problem statement, hypothesis of the experiment etc...Think about the answer, won't you?
