Answer:
How the gelatin is prepared can affect the result.
Explanation:
To perform this experiment efficiently, you need to prepare the jelly made from fresh fruit and the jelly made from canned fruit equally. That's because if you modify the ways of preparing the gelatins, they will show many differences and you won't be able to tell if this difference was caused only by the nature of the fruits, or by the way of preparation. Therefore, the way the gelatins were prepared can modify the experiment result and leave it imprecise and unreliable.
Answer:
All biological enzymes function best at particular pH values (most require pH 6 to 7) in the human stomach, the pH of 2-3 provides the environment required for the proper functioning of the digestive enzymes found there and this is the perfect condition for preservation of food and digestion of food.
Explanation:
The adding of basic material decrease acidity that happens due to the lower pH of the stomach. The very common basic material which is used to neutralize the acidity of stomach milk of magnesia.
The lower pH of the stomach cause acidity which is injurious to the health and also the mucous lining of the stomach. To balance is acidity milk of magnesia is required.
Answer:
A specific environmental factor that will cause a response to living things will be light from the sun.
Explanation:
An enhanced amount of light from Sun will cause the plants to have enhanced photosynthesis. Photosynthesis can be described as a process by which plants use light energy from the sun to convert carbon dioxide and water into sugar (food) and oxygen.
In animals, enhanced amount of light from the sun will cause sweating and vasodilation.
The process of photosynthesis won't occur in animals and the process of sweating won't occur in plants.
Answer:
Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.
Explanation:
<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.
Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.
This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.
