The Euclidean algorithm is based on the principle that the greatest common divisor of two numbers does not change if the larger number is replaced by its difference with the smaller number. For example, 21 is the GCD of 252 and 105 (as 252 = 21 × 12 and 105 = 21 × 5), and the same number 21 is also the GCD of 105 and 252 − 105 = 147. Since this replacement reduces the larger of the two numbers, repeating this process gives successively smaller pairs of numbers until the two numbers become equal. When that occurs, they are the GCD of the original two numbers. By reversing the steps, the GCD can be expressed as a sum of the two original numbers each multiplied by a positive or negative integer, e.g., 21 = 5 × 105 + (−2) × 252. The fact that the GCD can always be expressed in this way is known as Bézout's identity. The version of the Euclidean algorithm described above (and by Euclid) can take many subtraction steps to find the GCD when one of the given numbers is much bigger than the other. A more efficient version of the algorithm shortcuts these steps, instead replacing the larger of the two numbers by its remainder when divided by the smaller of the two (with this version, the algorithm stops when reaching a zero remainder). With this improvement, the algorithm never requires more steps than five times the number of digits (base 10) of the smaller integer. This was proven by Gabriel Lamé in 1844, and marks the beginning of computational complexity theory. Additional methods for improving the algorithm's efficiency were developed in the 20th century. The Euclidean algorithm has many theoretical and practical applications. It is used for reducing fractions to their simplest form and for performing division in modular arithmetic. Computations using this algorithm form part of the cryptographic protocols that are used to secure internet communications, and in methods for breaking these cryptosystems by factoring large composite numbers. The Euclidean algorithm may be used to solve Diophantine equations, such as finding numbers that satisfy multiple congruences according to the Chinese remainder theorem, to construct continued fractions, and to find accurate rational approximations to real numbers. Finally, it can be used as a basic tool for proving theorems in number theory such as Lagrange's four-square theorem and the uniqueness of prime factorizations. The original algorithm was described only for natural numbers and geometric lengths (real numbers), but the algorithm was generalized in the 19th century to other types of numbers, such as Gaussian integers and polynomials of one variable. This led to modern abstract algebraic notions such as Euclidean domains.

Photonasty is the movement of plant parts in response to the light. Seismonasty is the movement of plant parts in response to the touch. The leaves of Mimosa pudica drop down when touched due to seismonasty. Nyctinasty is the movement of plant parts in the dark or at night. Epinasty is the downward movement of plant parts due to increased growth on the upper surface of plant.

How is red soil form , write it's features?

Posted by M H Laskar 5 years, 7 months ago

CBSE > Class 10 > Social Science

1 answers

Yogita Ingle 5 years, 7 months ago

Formation : Most of the red soils have come into existence due to weathering of ancient crystalline igneous rocks. Characteristics / Features :
(i) Soils are loamy in deep depressions and in uplands. They consist of loose gravels and highly coarse materials.
(ii) The colour of these soils is generally red, often grading into brown, chocolate or yellow. The red colour is due to wide diffusion rather than high percentage of iron content. It looks yellow when it occurs in a hydrated form.
(iii) Soils are deficient in phosphoric acid, organic matter and nitrogenous materials but are fairly rich in potash. But crops are cultivated with the use of fertilizers.

Yogita Ingle 5 years, 7 months ago

Potential resources are those which have been found in a region, but not utilized.

The technology for its access is available, but not put into use.

Eg: Solar and wind energy development in Gujarat and Rajasthan.

Stock resources are those that have the potential to satisfy human needs.

But human beings do not have the suitable technology to access it yet.

Eg: Minerals and other fossil fuels.

Why does intestine in herbivores are larger than carnivores

Posted by Gokulakrishnan Santhanakrishnan 5 years, 7 months ago

CBSE > Class 10 > Science

2 answers

Sukhman Janjua 5 years, 7 months ago

Intestine of herbivores is larger than carnivores because herbivores have to digest heavy food like grass ,leavesetc .. where as carnivorous eat light food which can easily digested by them.

0Thank You

Yogita Ingle 5 years, 7 months ago

Cellulose forms the largest part of the herbivore’s food. Digestion of cellulose takes a longer time, because the enzymes are produced by the ruminant bacteria that live in the gut of the herbivore. Longer small intestine ensures that the food stays for a longer duration and proper digestion is possible. In the case of carnivores, cellulose is not present in the diet, thus the length of small intestine is less.

Yogita Ingle 5 years, 7 months ago

Exothermic Reaction: A chemical reaction in which heat is given out is known as exothermic reaction. For example
C(g) + O₂(g) → CO₂(g) + Heat Energy
NaOH(aq) + HCl (aq) → NaCl(aq) + H²O(l) + Energy

Endothermic Reaction: A chemical reaction in which heat energy is absorbed is known as endothermic reaction. For example
N2(g) + O₂(g) → 2 NO
C(s) + H₂O → CO(g) + H₂(g)

Meghna Thapar 5 years, 6 months ago

At the cellular level the muscle cells move by changing their shape so that they shorten. Muscle cells have special proteins that change both their shape and their

arrangement in the cell in response to nervous electrical impulses. When this happens, new arrangements of these proteins give the muscle cells a shorter form.

When the sense organ in our body is affected, it sends the message to the brain in the form of electrical impulses through the sensory neurons. The brain analyses this message and decides the action to be taken. The brain then sends out instructions to the muscles of the concerned body parts through motor nerves and the concerned body part acts accordingly.

Dominant trait: The trait which can express its effect over contrasting trait is called a dominant trait. It is expressed even in the presence of one copy of an allele for a particular character in the gene, i.e., it is expressed in the heterozygous condition.

Example: Yy represents dominant trait for yellow seed colour. Seed is yellow even when single copy is dominant allele Y is present.
