How does the nutrition in Paramecium happens |
|
Answer» Paramecium follows holozoic nutrition . Paramecium feed on microorganisms like bacteria, algae, and yeasts. The paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove. The food goes through the cell mouth into the gullet. Paramoecium takes in food at a specific point (through oral groove to mouth to gullet). Food such as bacteria or very small organisms are move to the specific spot (ingestion point) by the movement of cilia which are present on all over the single-celled body.From the gullet a food vacuole is formed which start circulating in the endoplasm. During circulation food is digested by enzymes. The digested food diffuses into the cytoplasm and undigested food is thrown out through **** pore. \tParamoecium is a unicellular aquatic organism.\tThe paramoecium has thin, hair like cilia all over its body.\tThe cilia move back and forth rapidly in water.\tWhen the cilia is present around, the mouth region of paramoecium move, back and forth. They sweep the food particles present in water into the mouth of paramoecium.\tThis is the first step in the nutrition of paramoecium which is called ingestion and is followed by digestion, absorption, assimilation and egestion. |

Explain digestive system of human |
|
Answer» \xa0The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we\'re upside-down.The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme.After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.After passing through the small intestine, food passes into the large intestine. In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food. Many microbes (bacteria like\xa0Bacteroides,\xa0Lactobacillus acidophilus,\xa0Escherichia coli, and\xa0Klebsiella) in the large intestine help in the digestion process. The first part of the large intestine is called the cecum (the appendix is connected to the cecum). Food then travels upward in the ascending colon. The food travels across the abdomen in the transverse colon, goes back down the other side of the body in the descending colon, and then through the sigmoid colon.Solid waste is then stored in the rectum until it is excreted via the ****. The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body. The digestive organs also move waste material out of the body. The enzymes in saliva help break down foods, and the lubrication function of saliva makes it easier for food to be swallowed. |

What are the roles of bicuspid valve and tricuspid valve in human circulatory system? |
|
Answer» Tricuspid valve: This valve opens to allow the blood to flow from the right atrium to the right ventricle. This valve is present in the junction of the right atrium and right ventricle.\xa0Bicuspid valve: This is also known as the mitral valve. This valve is present in the left atrium. This valve opens to allow the blood to flow from the left atrium to the left ventricle.\xa0\xa0 A heart valve opens or closes incumbent on differential blood pressure on each side. The four valves in the mammalian heart are: The two atrioventricular (AV) valves, the mitral valve (bicuspid valve) and the tricuspid valve, which are between the upper chambers (atria) and the lower chambers (ventricles). |

Human beings have \'double circulation\' . Justify |
|
Answer» In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.The double circulation of blood includes:(i) Systematic Circulation(ii) Pulmonary CirculationSystematic Circulation: It supplies oxygenated blood from left auricle to left ventricle, thereby pumped to various body parts. The deoxygenated blood is collected from the various body organs by the veins to pour into vena cava and finally into the right atrium (auricle). Right atrium transfers the blood into the right ventricle.Pulmonary Circulation: The deoxygenated blood is pumped by the right ventricle into the lungs for oxygenation. The oxygenated blood is brought back to left atrium (auricle) of the human heart. From left atrium, the oxygenated blood is pushed into the left ventricle. The left ventricle pumps oxygenated blood into aorta for systematic circulation.It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature. |

Classification of acid |
|
Answer» This means that the acid is classified on the basis of their source or origin. They are mainly of two types: Organic acid and Mineral acid. Organic Acid: This is the acid obtained from organic materials such as plants and animals. For e.g. Citric acid (Citrus fruits), Acetic acid (Vinegar), Oleic acid (Olive oil), etc. Acids are classified as\xa0Organic Acids and Mineral Acids. Acids which are derived from plants and animals, they are known as\xa0Organic Acids.\xa0For Example, Citric Acid from fruit. Mineral acids are inorganic acids such as\xa0Sulphuric Acid. They are dangerous to be used, so need more precautions.Acids are also classified as\xa0Strong Acids or Weak Acids. Strong acid is an acid, that completely dissociates into ions in aqueous solutions.\xa0For Example, Sulphuric Acid, Hydrochloric Acid.Weak acid is the one which does not dissociate completely into ions in aqueous solutions.\xa0For Example,\xa0Acetic Acid. |

Mention the purpose of blackening the interior of a solar cooker |
|
Answer» Solar cookers are blackened from inside because black absorbs more heat from sun as compared to other colours. EXPLANATION: When more heat is absorbed by the blackened interiors, the food is cooked faster as more heat is absorbed inside the cooker. ... This helps in rapid increase of temperature inside the solar cooker The purpose of blackening the interior of a solar cooker is that the black surface absorbs more heat radiations of incident solar energy (about 98%) as compare to white or other light coloured surface. |

What is magnetic field lines? |
|
Answer» These are imaginary lines along which the iron fillings would arrange themselves in circular orbits due to the force acting on them. Thanks The path along which north pole moves in a\xa0magnetic field\xa0is called\xa0magnetic lines\xa0of force or\xa0magnetic field\xa0line. They show the direction and strength of the\xa0magnetic field. If\xa0magnetic field lines\xa0are very close to each other in a particular region, then the strength of the\xa0magnetic field\xa0in that region is very large.\xa0A\xa0magnetic field line\xa0is an imaginary curve along which a free unit north pole tends to move.\xa0Magnetic field lines\xa0always start from north pole and end on the south pole. The tangent to the\xa0magnetic field lines\xa0at any point gives the direction of the\xa0magnetic field\xa0at that point. |

a coin immersed in water appear displaces or raised hand diagram |
| Answer» It happens due to the, phenomenon of refraction of light. When the rays of light from the coin, in the denser medium, fall on the interface separating the two media, the rays of light move away from the normal after refraction. The point from which the refracted rays appear to come gives the apparent position of the coin. As the rays appear to come from a point above the coin, therefore, the coin seems to be raised. | |
