Question textThis is a picture of a starch hydrolysis test, used to measure the amylase activity in plants. Amylase has been extracted from germinating barley seeds and this extract was used to determine the amylase activity by measuring the time taken to reach the achromic point. Please note that the number in the left corner of each dropwell refers to time, measured in minutes.Select the appropriate answers in the paragraph below.Amylase is a(n) Answer 1 Question 19[select: , carbohydrate, amino acid, lipid, enzyme, nucleotide] that is primarily responsible for breaking down starch to Answer 2 Question 19[select: , raffinose, glycogen, lactose, trehalose, sucrose, maltose, xylose, amylose].In the image provided, the most accurate estimate for the achromic point is Answer 3 Question 19[select: , 7 minutes, no achromic point reached, 2 minutes, 13 minutes, 8 seconds]. The subsequent Benedict’s test revealed a ‘brick red’ coloured precipitate forming from the product of the starch hydrolysis test. This confirms that the product Answer 4 Question 19[select: , is a non-reducing sugar, contains undigested starch, is a reducing sugar, is not maltose or glucose].多项填空题

It is extremely flexible when wet, and is adapted to create interesting shapes. Many urban public buildings, such as universities, have also used concrete as the main material to indicate strength and permanence. Instead of keeping Brutalist buildings, many are being demolished to make space for modern styles. However, this does not acknowledge the cultural history of these buildings, and is not sustainable.
