Kaisi Rahi☺ Infinity (symbol: ∞) is a concept describing something without any bound or larger than any natural number. Philosophers have speculated about the nature of the infinite, for example Zeno of Elea, who proposed many paradoxes involving infinity, and Eudoxus of Cnidus, who used the idea of infinitely small quantities in his method of exhaustion. Modern mathematics uses the general concept of infinity in the solution of many practical and theoretical problems, such as in calculus and set theory, and the idea also is used in physics and the other sciences.In mathematics, "infinity" is often treated as a number (i.e., it counts or measures things: "an infinite number of terms") but it is not the same sort of number as either a natural or a real number.Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities).[1] For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable Infinity is described for somthing that cannot end or is boundless |

What is double circulation .what are advantages of double circulation |
|
Answer» The majority of mammals (including humans) utilize a double circulatory system. This means we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.the double-pump heart has two main advantages:1) The ability to create more pressure to pump blood round the system.2) The separation of oxygen-rich and oxygen-poor blood (which does not occur in frogs). The circulatory system in which blood travels twice through the heart in one complete revolution is called double circulation. It helps to maintain body temperature |
