ural selection: Those variations which give survival advantage to an organism are selected in nature and such traits increase in population.(II) Genetic drift: It occurs due to change in GENE frequency due to accumulation of PARTICULAR type of genes.(III) Geographical isolation: It leads to change in gene frequency leading to expression of one type of traits in a geographically isolated population.(iv) Migration: It leads to flow of a particular type of gene in a specified population.

s law of universal GRAVITATION: "Newton's law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them."Coulomb's law: "The MAGNITUDE of the Electrostatics force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distances between them."How did SIR Isaac Newton and Sir Charles Augustine De Coulomb come to know that the force, gravitational or coulomb's, is inversely proportional to the square of the distance between two point masses or charges, why didn't they just say that the force is inversely proportional to the distance of two bodies from each other or two charges? There must have been something that MADE them formulate these inverse-square laws

R REFLECTION*reflection such that the ANGLE OFREFLECTION of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence.*DIFFUSE REFLECTION*Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just ONE angle as in the case of specular reflection. ... Many common materials EXHIBIT a MIXTURE of specular and diffuse reflection.

tation is the clearing of trees without the intent of replacing them or reestablishing a stand of trees. Learn reasons for deforestation and discover the CONSEQUENCES of this process in all forests, including tropical forests.The World's ForestsForests mean different things to different people. Outdoorsmen and nature lovers appreciate them for their recreational value. Those in the timber industry appreciate them for their economic value, and MANY critters and plants call the forests and tropical forests HOME. For humans, animals and biologically diverse plants, forests provide raw materials and habitats that are vital to sustainable life. However, forests can easily be taken for granted and become a casualty of civilization.If the human population continues to aggressively clear forests to exploit their natural RESOURCES or make room for PROGRESS, the benefits of this important ecosystem could be lost. In this lesson, we will look at the causes of deforestation and discuss some of the consequences of this process.hope you like it

E....The DIFFERENT effects of air pollution on HUMAN being are many such as....Human beings suffer with some respiration problems such as, breathing problems, infections, watery eyes etc...Some air POLLUTANTS also effects on the FOOD which human beings are consuming etc...HOPE THIS HELPS U DEAR.

now that 1 MOLECULE of helium is equal to 4g So, number of MOLES in 52 g of he will be52/4= 13 molesTherefore, there are 13 miles in 52g of he.Hope it HELPS !!!

tation is when HUMANS remove or clear large areas of forest LANDS and related ECOSYSTEMS for non-forest use. These INCLUDE clearing for farming purposes, ranching and urban use. HOPE U LIKE MY ANSWER

्तु के वास्तविक आकार को बदले बिना उसको अपने वास्तविक आकार से बड़ा दिखाना आवर्धन कहलाता है। वस्तु जितने गुना बड़ी दिखती है, उसे 'आवर्धन' कहते हैं। यदि आवर्धन १ से अधिक है तो इसका अर्थ है कि वस्तु अपने वास्तविक आकार से बड़ी दिक रही है।

Mass Dalton's ATOMIC Theory Stoichiometry   Laws of Chemical Combinations Chemistry is the study of the change of matter from one form to the other. These changes often occur as a result of the combination of two different types of matter. There are certain rules that govern the combination of different elements to form compounds. These rules are, what we CALL, the laws of chemical combinations. There are FIVE basic laws of chemical combinations that govern the chemical combinations of elements. What are they and what do they SIGNIFY? Let us read more about these laws in the section below. 1) Law of Conservation of Mass French chemist, Antoine Lavoisier in 1789, studied this law. This law states that “In all physical and chemical changes, the total mass of the reactants is equal to that of the products” or “Mass can neither be created nor destroyed.” We also refer to this law as the law of INDESTRUCTIBILITY of matter. The mass and energy are interconvertible but the total sum of the mass and energy during any physical or chemical change remains constant.

s of chemical combination describe the basic principles obeyed by interacting atoms and molecules, interactions that can include MANY different combinations that happen in many different ways. This AMAZING DIVERSITY of interactions allows for an ASTOUNDING variety of chemical reactions and compounds. Spontaneous chemical reactions happen constantly, shaping the world around us, while humans engineer specific reactions to our benefit and attempt to curb reactions that hurt us. Though chemical reactions can be as complex as they are numerous, they are all fundamentally governed by these same guiding laws of chemical combination, which lay the groundwork for analysis of chemical reactions. They give a mathematical formulation and allow predictability given initial conditions. They are the launch pad from which we jump off to creating all SORTS of wild compounds and phenomena. And while chemistry is still difficult and intricate, with the laws of chemical combination on our side, we can begin to make some headway.

swer is = see downPredicting the cutoff MARKS this year is a tough job. There is a change in the exam pattern, no language PAPER, the increase in total marks from 150 to 200. The cutoff of NTSE stage 1 will be released state wise along with the result. As you have not mentioned the name of your state you can check the LINK below to have a complete IDEA and check the previous year cutoff also.yo thank u for asking[ MR = BRAHMAN ]~...

electric bell jar and a r type class Bell jar. the electric bell is suspended inside the applied Bell jar. the bell jar is connected to a vacuum pump as SHOWN in the figure. if you PASS this page you will be able to hear the bell. now start the vacuum pump. when there is inside the jar is pumped out gradually the sound becomes fainter although the same current is PASSING through the bell after sometime when LESS are is left inside the bell jar you will see a VARIABLE sound or removal of air completely no sound is heard

te here is your ANSWER⤵The Sun is not a “huge ball of fire”; it is a nuclear fusion reaction, FUSING Hydrogen into Helium and a release of ENERGY and the Sun is (on AVERAGE) about 93,000,000 miles away which greatly reducing its intensity on the Earth. And once the radiation from the Sun gets to the Earth it is ATTENUATED by our atmosphere.Hope this answer will help you..《《

because the conditions for the processes of PRECIPITATION, condensation and evaporation are available in the atmosphere at all times.so hence the processes CONTINUE all the time till the conditions for them to work cease to action.there is hence continuous process of evaporation of SEA water and condensation of it in the troposphere to form clouds and when the clouds GET saturated they commence with the precipitation process  .HOPE it helped
