Answer» The digestion of protein takes place in stomach. Small intestine secret intestinal juice and digest all food Stomach and small intensin. The protein is digested in small intestine. The digestion of proteins begin in the stomach where HCl acts on pepsinogen to convert it into pepsin. Pepsin converts proteins into peptons and proteosis. In the duodenum (small intestine), the enzyme trypsin converts peptons and proteosis into peptides. The intestinal peptidase converts peptides into amino acids, which is absorbed by the body. The digestion of proteins finish here. |

Why glucose is better option to get instant energy |
|
Answer» Glucose is the simplest form of sugar,hence it breaks down easily and releases energy. Therefore glucose is a better option to get energy. Because it is in simplest form and easily absorbed in our blood . It is directly absorb as just they are .It doesn\'t require digestion Glucose is full of oxygen. When we consume glucose the oxygen present in it absorb easily by the red blood cell in a easier way and thus we get instant energy Glucose is the better option to get instant energy because it is the simplest form of food and it does not need to digest |

How to make working model of human heart |
| Answer» The heart is a muscular organ that pumps blood to different parts of the body through blood vessels. The human heart has 4 chambers: 2 atria and 2 ventricles. The atria are used to receive blood from the body and the ventricles pump blood to the body. The heart and the blood vessels are part of the circulatory system, which sends blood around and around your body in one direction. Your heart has valves that allow blood to move forward but prevent it from moving backwards.Your heart works alongside your lungs. Every time you breathe, you use your lungs. The lungs are soft, sponge-like organs that expand when filled with air, like a balloon. As you breathe in, your lungs take in oxygen which our blood picks up. This goes to the heart, which then pumps the oxygen-rich blood through your body for your cells to use. Once your cells use the oxygen, they release carbon dioxide back into the blood. This blood goes back to the heart, where it is pumped to the lungs, which then breathe out the carbon dioxide gas. Then your blood picks up more oxygen and the cycle continues.In our heart model, the cup is your heart, the pressing motion from your finger on the balloon is the pumping muscle, the water is your blood, the straw with the balloon on it is the atrial valve that keeps "blood" from pumping out in the wrong direction, and the other, open-ended straw is the ventricle through which the "blood" flows. | |

Difference between assimilation and digestion.3 points ,plz answer this ?? |
|
Answer» Thanks?? \tAssimilationDigestion(i) Assimilation is using the absorbed materials.(i) Digestion is the process of breaking down of food by mechanical and chemical means.(ii) Assmilation is the delicate process where the nutrients must pass through the cellular membrane into your cells.(ii) It utilises several enzymes. It is a step-wise process occurring in stages in different parts of the alimentary canal.\xa0(iii) Assimilation helps in utilising the digested food for obtaining energy, building up new tissues and repair of old. tissues.(iii) Digestion helps in breaking down complex food materials into simpler end products.\xa0\t |

What is meant by boiling tube? |
| Answer» A boiling tube is a small cylindrical vessel used to strongly heat substances in the flame of a Bunsen burner. A boiling tube is essentially a scaled-up test tube, being about 50% larger. They are designed to be wide enough to allow substances to boil violently as opposed to a test tube, which is too narrow; a boiling liquid can explode out of the end of test tubes when they are heated, as there is no room for bubbles of gas to escape independently of the surrounding liquid. Boiling tubes are made from borosilicate glass that can withstand high temperatures. | |
