(IGP) IAS Pre Paper - 2: GS - Basic Numeracy - Unitary Method Posted: 29 Dec 2011 12:16 AM PST Basic Nmeracy Unitary Method Unitary method is the basic area of arithmetic. In the CSAT paper this portion of Basic numeracy will help you to solve myriad problems. Direct Proportion Two quantities are said to be directly proportional, if on the increase in one the other increases proportionally or on the decrease in one the other decreases proportionally. eg, More the numbers of articles, More is the cost. More the number of workers, More is the work done. Less the number of articles, Less is the cost. Less the number of workers, Less is the work done. Indirect Proportion Two quantities are said to be indirectly proportional, if on the increase in one the other decreases proportionally or on the decrease in one the other increases proportionally. read more © 2011 www.upscportal.com INTEGRATED Guidance Programme for IAS 2012(CSAT) :: CSAT Sample Papers :: Current Affairs | CSAT Syllabus | UPSC MAINS PAPERS Get Your Dream Job.

(IGP) IAS Pre: GS - Science & Technology : Biology - The Circulatory System Posted: 28 Dec 2011 11:13 PM PST Biology The Circulatory System INTRODUCTION Living things must be capable of transporting nutrients, wastes and gases to and from cells. Single-celled organisms use their cell surface as a point of exchange with the outside environment. Multicellular organisms have developed transport and circulatory systems to deliver oxygen and food to cells and remove carbon dioxide and metabolic wastes. CIRCULATORY SYSTEMS IN SINGLE CELLED ORGANISMS Single-celled organisms use their cell surface as a point of exchange with the outside environment. Sponges are the simplest animals, yet even they have a transport system. Seawater is the medium of transport and is propelled in and out of the sponge by ciliary action. Simple animals, such as the hydra and planaria lack specialized organs such as hearts and blood vessels, instead using their skin as an exchange point for materials. This, however, limits the size an animal can attain. To become larger, they need specialized organs and organ systems. CIRCULATORY SYSTEMS IN MULTICELLULAR ORGANISMS Multicellular animals do not have most of their cells in contact with the external environment and so have developed circulatory systems to transport nutrients, oxygen, carbon dioxide andmetabolicwastes.Components of the circulatory system include i. Blood: a connective tissue of liquid plasma and cells ii. Heart: a muscular pump to move the blood iii. Blood vessels: arteries, capillaries and veins that deliver blood to all tissues TYPES OF CIRCULATORY SYSTEMS (a) The open circulatory system The open circulatory system, examples molluscs and arthropods. Open circulatory systems (evolved in insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood. The resulting blood flow is sluggish. read more © 2011 www.upscportal.com INTEGRATED Guidance Programme for IAS 2012(CSAT) :: CSAT Sample Papers :: Current Affairs | CSAT Syllabus | UPSC MAINS PAPERS Get Your Dream Job.
