Biology Homework Assistance
The most challenging aspect of biology education is making students grasp the microscopic realm of biology, delving into cells and exploring genes and molecules. However, with the advent of information technology, biology homework assistance can play a crucial role when neither words nor illustrations suffice to elucidate biology concepts.
QuestionAI is an online biology learning platform that aids in learning and mastering biology concepts, featuring a variety of experiments and corresponding exercises, a departure from conventional biology question aids. Here, you can simulate experiments to replicate experimental scenarios, delving deeper layer by layer to comprehend and internalise key concepts.

- (c) A group of students investigated the action of salivary amylase. The students: - collected a sample of salivary amylase - put a different mathrm(pH) solution and 5 mathrm(~cm)^3 of a food substance in each of 6 test tubes - added 1 mathrm(~cm)^3 of salivary amylase to each of the 6 test tubes - recorded the amylase activity after 10 minutes. The results are shown in the table. pH & 7 & 6 & 5 & 4 & 3 & 2 }(l) Amylase activity in arbitrary units & 12 & 10 & 3 & 0 & 0 & 0 (i) Name the food substance that amylase breaks down. Starch (ii) Suggest what happens to the breakdown of this substance when food reaches the stomach. Use information from the table to help you to answer this question.
