Answer and Explanation:
- Ingestion of foods and liquids
- Mechanical processing of food materials and liquids
- Warming the body with heat released from the digestive organs as they process food.
Digestion is the breakdown of food substances by enzymes to simpler compounds that can be absorbed. Digestion begins in the mouth. Once food is ingested in the mouth, it is chewed and broken into small particles suitable for swallowing. Mechanical procesing of food is through the wave-like contractions of the muscular walls of the alimentary canal called peristalsis. Churn and pound food mixing it with digestive enzymes.
After digestion, absorption and assimilation, the final product is oxidized to provide energy to the body.
Because bile contains salts and digestive compounds and lipase is a digestive enzyme, you might create a simple qualitative experiment to test the action of bile and lipase. Bile is first used to emulsify and break down food entering the small intestine, and lipase is used afterwards by the pancreas to break down fats. With this information, I suggest this experiment:
1) Label 4 test tubes A, B, C, and D. Divide the fat solution equally into the 4 tubes.
2) In tube B, add an x amount (but not the whole volume) of the bile solution.
3) in tube C, add a y amount (but not the whole volume) of lipase solution.
4) in tube D, add the x amount of bile and the y amount of lipase solution.
5) Swirl/mix until everything looks homogenized/settled.
6) tube A is your control. Compare the 3 other tubes to it and write observations. You should be able to make conclusions about the role of bile in digesting a fatty solution, and the extent of digestion with and without the additional lipase.
Hope this is helpful!~ There are certainly many other possible experiments.
Answer:
3 Ba(OH)2 + Fe2(SO4)3 = 2 Fe(OH)3 + 3 BaSO4
Explanation:
The word 'science' is derived from the Latin word 'scientia' which means knowledge. Therefore, science is about gaining knowledge either through observing, studying, experience, or practice. Entire knowledge acquired through science is about discovering truths, finding facts, uncovering phenomenon hidden by the nature.
Virchow was correct when he concluded that cells arise from others cells, i.e., new cells are born through the division of one cell into two through the process of mitosis. The need for new cells continues throughout our lives, but it is greatest in early life. A fertilized egg divides into two cells, which give rise to four, and those give rise to eight, and then to 16, and 32, and 64, and so on. In a fully grown adult, of course, the rate of cell proliferation is much less, and under normal circumstances, cell division in an adult takes place only when signals indicate the need to replace cells that have been lost, damaged, or worn out. Basically when your young so is your cell and ask you get older they get stronger
