What are ingrediants? |
|
Answer» Answer: An ingredient is a substance that forms part of a mixture (in a general sense). For example, in cooking, recipes specify which ingredients are used to prepare a specific dish. Many commercial products contain secret ingredients that are purported to make them better than competing products. In the pharmaceutical industry, an active ingredient is that part of a formulation that yields the effect expected by the customer. National laws usually require prepared food products to display a list of ingredients, and specifically require that certain additives be listed. In most developed countries, the law requires that ingredients be listed according to their relative weight[1] in the product. If an ingredient itself consists of more than one ingredient (such as the cookie pieces which are a part of "cookies and cream" flavor ice cream), then that ingredient is listed by what percentage of the total product it OCCUPIES, with its own ingredients displayed next to it in brackets. The term constituent is OFTEN CHOSEN when referring to the substances that constitute the tissue of living beings such as plants and people, because the word ingredient in many minds connotes a sense of HUMAN agency (that is, something that a person combines with other substances), whereas the NATURAL products present in living beings were not added by any human agency but rather occurred naturally ("a plant doesn't have ingredients"). Thus all ingredients are constituents, but not all constituents are ingredients. |

Name all the important processes in the chapter-The fundamental unit of life class 9th |

Answer» 1. Plasma/Cell membrane: This is the outermost covering of the cell that separates the CONTENTS of the cell from its external environment. The plasma membrane allows or permits the entry and EXIT of some materials in and out of the cell so the cell membrane is called a selectively permeable membrane. Some substances like CO2 or O2 gases can move across the cell membrane by a process called diffusion. The movement of water molecules (liquid) through such a selectively permeable membrane is called osmosis. Osmosis is the PASSAGE ot water from a region of high water CONCENTRATION through a semi-permeable membrane to a region of low water concentration. If the medium surrounding the cell has a higher water concentration than the cell, the cell will gain water by osmosis. Such a solution is known as hypotonic solution. If the medium has exactly the same water concentration as the cell, there will be no net movement of water across the cell membrane. Such a solution is known as isotonic solution. If the medium has a lower water concentration then the cell will lose water by osmosis. Such a solution is known as hypertonic solution. The plasma membrane is flexible and is made up of organic molecules called lipids and proteins. The flexibility of cell membrane also enables the cell to engulf in food and other material from its external environment. Such process is known as endocytosis. It is observed in Amoeba. |

Explain the process that will take place in an animal cell kept in hypotonic solution |
|
Answer» Answer: If you place an animal or a PLANT CELL in a HYPERTONIC solution, the cell shrinks, because it loses water ( water moves from a higher CONCENTRATION inside the cell to a lower concentration outside ). ... Hypotonic SOLUTIONS have more water than a cell. Tapwater and pure water are hypotonic Explanation: |

State the roll of the functions in digestive system (1) digestive enzymes (2) hydrochloric acid (3)villi |
|
Answer» Answer: Explanation:Our stomach have bunch of enzymes in our body which PLAYS a very essential role in digestion there are many enzymes like PANCREATIC juices from pancreas , Bile juice from liver etc . Be more specific to get the answer for a particular enzyme. Secondly the HCL (Hydro chloric acid ) is present in the stomach and it's have very low ph it have couple of reasons - 1) The low ph of HCL helps to kill the pathogens which might enter with food. 2) Also the low ph of HCL (1.8) activates the enzyme pepsinogen into pepsin which converts proteins into proteoses and peptones. The innermost LAYER lining the lumen of the alimentary canal in the mucosa this layer forms irregular folds called (Rugae) in the stomach and small FINGER like foldings called villi in the small intestine these villi increases the surface area for the absorption.
