Define variation and give its importance? |
|
Answer» Join betternation.xyz This is a site where u can have a lot of friends and fun ? ? \tVariation can be defined as the difference between the cells, organisms or group of organisms belonging to a particular species by environmental factors (phenotypic variation) or genetic differences (genotypic variations).\tIt is caused by gene mutations due to certain environmental factors and various combinations of genetic material.\xa0\tVariation is important because it causes evolution and is the basis of heredity.\tIt is advantageous to a population as it enables few individuals to adapt to the environment changes thus, enabling the survival of the population. |

What are the sign convention for reflection by sperical mirrors? |
|
Answer» Cartesian Sign Convention:\xa0In the case of spherical mirror all signs are taken from Pole of the spherical mirror, which is often called origin or origin point. This sign convention is known as New Cartesian Sign Convention.\tSign is taken as + (positive) behind the spherical mirror. For example if an image is formed behind the mirror, the distance of image is taken as + (positive) from pole along the principal axis.\tThe height of is taken as + (positive) above the principal axis and taken as – (negative) below the principal axis.

Advantage of parallel circuit |
|
Answer» 1. Parallel circuits provide the same voltage to every source and appliance in the circuit, thus all appliances work efficiently.2. In a parallel circuit if one appliance is fused, the current continues to flow through the others. Hence other appliances continue to work.3. The equivalent resistance in the parallel connection of resistors decreases thus, more current than one source can produce is obtained. Unless all appliances in parallel have the same voltage, current would flow from one source into the other. This will result in loss of power.

Explain the female reproductive system with the help of an diagram |
| Answer» In human females, a pair of ovaries is located in the abdominal cavity near the kidney. The ovaries perform dual function of: (i) production of female gamete (ovum) and (ii) secretion of female hormones (estrogen and progesterone). Each ovary is composed of ovarian follicles. At puberty, these follicles undergo maturation to produce ova.Near the posterior end of ovary, a funnel like structure leads into a long convoluted tube called fallopian tube. The fallopian tubes from both sides open into a muscular structure, the uterus. Uterus opens into the ******. ****** is a tubular structure also called the \'birth canal", as through this canal the young one is born after completion of development inside uterus. In females, urinary opening (urethra) and vaginal openings are separate. | |

Why do we need lungs?? |
|
Answer» Lungs help in respiration remove the wastes from the body The main function of\xa0lungs is respiration. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the\xa0thin-walled air sacs called alveoli.The lungs are also important in the body\'s defense against infection and other harmful environmental factors.\xa0The lungs provide the second line of defense. Inhaled particles\xa0or infectious agents like bacteria and viruses pass through the mouth or nose and lodge in the lungs. Mucus, a sticky fluid produced in the lungs, can trap these inhaled agents and aid the lungs\' protective white blood cells (macrophages, neutrophils) in the engulfment and destruction of bacteria and other harmful materials. For respiration |

Transportation in human beings. |
|
Answer» \tTransportation can be defined as the movement of any substance from one place to another.\tWater and nutrients required for all metabolic activities should be transported in the body of plants and animals.\tThe waste material or excretory products should also move to the region of excretion.\tTransportation in animal takes place through circulatory system which includes blood, blood vessels and heart.\tBlood is a fluid connective tissue consists of fluid medium called plasma.\tFunctions of blood are to transport food, oxygen, carbon dioxide, nitrogenous wastes, salts.\tA pumping organ is necessary to push the blood around the body.\tHeart is the muscular pumping organ which pushes the blood around the body.\tTube like structure through which carry blood to cells, tissues and organs are called as blood vessels.\tTwo special blood vessels are arteries and veins.\tAfter reaching the organs, the arteries divide in to small branches called as capillaries.\tHeart in another component of circulatory system which is also known as pumping organ.\tHeart consists of four chambers separated by a partition to avoid mixing of oxygenated and deoxygenated blood.

Why small intestine is hollow?? |
|
Answer» The small intestine is made up of 3 layers,\xa0the duodenum, jejunum, and ileum. It contains enzymes like trypsin and chymotrypsin which breaks down food to the maximum possible with the help of bile from the liver. Peristalsis also takes place\xa0in this organ. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.Contents of the small intestine starts from a semi-solid form till the end in a liquid form after passing through the organ. Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or colon. Stomach Large intestine |

Define electric potential and electric field |
|
Answer» The direction of the\xa0field\xa0is taken to be the direction of the force it would exert on a positive test charge. The\xa0electric field\xa0is radially outward from a positive charge and radially in toward a negative point charge. It is created by electric charge... Electric potential at a point in an electric field is defined as the work done in moving a unit positive charge from infinity to that point. An electric potential is amount of work needed to move a unit charge from a reference point to a specific point inside the field without producing an acceleration. |

What are contributions of Mendel for inheritance of traits? |
| Answer» Gregor\xa0Mendel, through his work on pea plants, discovered the fundamental laws of\xa0inheritance. He deduced that genes come in pairs and are\xa0inherited\xa0as distinct units, one from each parent.\xa0Mendel\xa0tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive\xa0traits.\xa0Mendel\xa0carried out his key experiments\xa0using\xa0the garden pea, Pisum sativum, as a model system. Pea plants make a convenient system for\xa0studies\xa0of\xa0inheritance, and they are still\xa0studied\xa0by some geneticists today. | |

Why o2 is very reactive |
| Answer» Oxygen\xa0is very\xa0reactive with\xa0Alkali metals. Alkali metals are given the name alkali because the oxides of these metals react with water to form a metal hydroxide that is basic or alkaline. Lithium produces an oxide, sodium produces a peroxide, and potassium, cesium, and rubidium produce superoxides.\xa0Due to its electronegativity,\xa0oxygen\xa0forms stable chemical bonds with almost all elements to give the corresponding oxides. Cesium is\xa0so reactive\xa0with\xa0oxygen\xa0that it is used as a getter in vacuum tubes. | |

An object is placed at focus |
|
Answer» When object placed at F in concave mirror image formed at infinity. ( i ) Real and inverted. ( ii ) Highly magnified. When\xa0object\xa0is at\xa0focus\xa0of the concave mirror. hence the image is formed at infinity and image is real, inverted and highly magnified. And Plane\xa0mirrors\xa0and\xa0convex mirrors\xa0only produce virtual\xa0images. Only a concave\xa0mirror\xa0is capable of producing a real\xa0image\xa0and this only occurs if the object is located a distance greater than a focal length from the\xa0mirror\'s\xa0surface |
