So results are valid all controlled factors must be the same.

Using the same amount of saliva and starch solution ensures that the ratio of reactants is consistent across experiments, allowing for accurate comparisons and reliable results. Varying the amounts could introduce variability that may affect the outcome of the experiment and make it difficult to draw meaningful conclusions.

About how much saliva does your body make everyday?
On average, a person produces about 0.5 to 1.5 liters of saliva per day. The amount can vary based on factors like age, hydration levels, and overall health. Saliva plays important roles in digestion, lubrication, and protection of the mouth.
How do you explain when we add starch solution saliva dilute alkali and did not presence of starch and presence of glucose?
The enzyme amylase in the saliva broke the starch down into glucose.
Do both men and women produce the same amount of saliva?
no
How would benedict's solution mixed with starch and saliva react?
Benedict's solution is used to test for the presence of reducing sugars. When mixed with starch and saliva, the reaction would depend on whether the starch in the solution has been broken down by the enzyme amylase present in saliva into simpler sugars. If starch is broken down into reducing sugars like maltose or glucose, then the Benedict's solution would change color from blue to green, yellow, orange, or red, indicating a positive result for reducing sugars.
When are saliva and semen important in DNA analysis?
in sex crime
What colour is the colour when mixing saliva and water using the Benedict solution?
When mixing saliva, water, and Benedict's solution, the initial blue color of the Benedict's solution will change to green, yellow, orange, or red, depending on the presence and concentration of reducing sugars like glucose in the saliva. This color change is indicative of the amount of reducing sugars present in the solution.
Is saliva a solution?
Yes, saliva is a solution of hydrochloric acid, water, and other bodily fluids.
What are the experiments that show that a substance in saliva can convert starch into reducing sugar?
Ptylan (or maybe it's ptylin), is the enzyme in saliva
Action of saliva in carbohydrate solution?
lysozyme
What happened to the starch solution after you have added saliva?
Saliva contains enzymes that break down starch into simpler sugars like maltose. After adding saliva to a starch solution, the amylase enzyme in saliva breaks down the starch molecules into these simpler sugars, leading to a sweet taste in the solution due to the presence of maltose.

How does one clean contact lenses?
Firstly, do not lick them! Your saliva contains a huge amount of bacteria that can cause conjunctivitis and worse. Wash your hands, place the lens and some cleaning solution in your hand, and rub the lens with your finger. Rinse it with rinsing solution, and store it in a case with storage solution.
What happens when phenolphthalein mixes with saliva?
Phenolphthalein is a pH indicator that turns pink in basic solutions, and colorless in acidic solutions. Normal pH of saliva ranges between 6.2 (acidic) and 7.4 (basic), with 7 being neutral pH. So, the answer is, "it depends." Is the saliva acidic, or basic?
What color does saliva turn into with the Benedict's solution?
Benedict's solution changes colors (blue to green to yellow to orange to red) in the presence of "reducing" sugars, which are not normally present in saliva. An interesting experiment, however, is testing table sugar with Benedict's solution. Table sugar is a glucose sugar joined to a fructose sugar, so they cannot react with the Benedict's solution and no color change occurs. Put table sugar in your mouth for a few moments, and then test the saliva. Now the Benedict's solution will react! (The reason: saliva has an enzyme, amylase, which breaks the glucose and fructose apart so that they can react to the Benedict's.)
Can anything reduce the amount of saliva you produce?
Dehydration.
How do you measure dogs saliva?
Simple, you get a measuring cup, possibly from your kitchen, to measure liquids. Take the amount of saliva from dog (do not force dog to give saliva, that is cruel) and measure the amount from the tool. Dog saliva is a needed ingredient in many food dishes, including many seafood dishes.
Can saliva causes HIV aids?
Yes, but it would take an ENORMOUS amount of saliva to transmit the virus. Like a few hundred gallons.
