Answer» Answer: DIGESTION in human:In chemical digestion, enzymes break down food into the small molecules the body can use. In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a FORM of mechanical digestion, and the wetting contact of saliva. Peristalsis movement:Peristalsis is a series of wave-like muscle contractions that moves food to different PROCESSING stations in the digestive tract. . The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where it is churned into a liquid mixture called CHYME.

What are hypotonic,isotonic and hypertonic solutions?give examples |
|
Answer» Answer: A hypotonic solution is a solution which has more concentration of water.The cells gain water and swell up if the surrounding media is hypotonic. A HYPERTONIC solution is a solution which has less concentration of water. The cell loses water and shrinks if the surrounding media is hypertonic. An isotonic solution is a solution which has exactly the same concentration of water as that in a cell.The cell's SIZE remains unchanged.An EQUILIBRIUM is maintained. Hope this helps!!!

Write the type of energy conversion that takes place through stomata |
|
Answer» Answer: Photosynthesis takes place primarily in leaves and stems. The overall chemical reaction under photosynthesis can be written as “6H2O + 6CO2 -----> C6H12O6+ 6O2.” The process occurs in two stages. The first STAGE is the reaction of LIGHT used to form high energy molecules. The energy harvested in the light reaction is stored in cells in the form of a chemical named as ATP, or ADENOSINE TRIPHOSPHATE. The second stage of photosynthesis is called the Calvin Cycle Reaction. |
