Question

Greg and Andrea are trying to find out how long it takes amylase a digestive enzyme found in saliva to break down a sample of starch they put their sample in the breaker and covered it with their own saliva after allowing it to sit on the lab table for one hour they measure the remaining surface area of the starch what is the best way they could improve their experiment

A. Take consistent amounts of their saliva samples with varying amounts of starch
B. Take consistent amount of saliva samples and consistent amount of starch
C. Take varying amounts of saliva samples and a consistent amount of starch
D. Take during amounts of saliva samples and varying amounts of starch

Answer 1

Take consistent amounts of their saliva samples with varying amounts of starch

Step-by-step explanation:

Answer 2

A. Take consistent amounts of their saliva samples with varying amounts of starch

Step-by-step explanation:

Amylase is an enzyme that is required for the digestion of carbohydrates (starch). The enzyme amylase can be found in saliva.

In other to find out how long it would take for amylase to digestive starch, you would have to take consistent amount of saliva samples with varying amount or starch because amylase is an independent variable while the starch is a dependent variable in this experiment.
