The genomic content of the nucleus is constant for a given species where as the extrachromosomal DNA is found to be variable among the members of a population. Explain.

The distance moved by a particle in time from centre of ring under the influence of its gravity is given by x=a sin omegat where a and omega are constants. If omega is found to depend on the radius of the ring (r), its mass (m) and universal gravitation constant (G), find using dimensional analysis an expression for omega in terms of r, m and G.

According to I.C slater effective nuclear charge, Z^(**) , due to screening, is not exactly equal to the actual nuclear charge Z of the nucleus of the atom. Z^(**) depends on the type of orbitals in which the electron is housed, and on the ability of other electrons in more penetrating orbitals to screen the electron in question from the nucleus. The relative extent to which the various orbitals penetrate the electron clouds of other orbitals is s gt p gt f . The effective nuclear charge Z^(**) due to screening is given by Z^(**)=Z-sigma , where Z is the atomic atomic number and sigma is the slater screening constant values 0 lt sigma lt Z Screening effect of one electron in the outermost orbitals, is not considered in calculate of sigma . What is the value of Z^(**) for Rb(37) ?

Study the figures below and answer the following : (a)Mention the specific geographical region where these organisms are found. (b)Name and explain the phenomenon that has resulted in the evolution of such diverse species in the region. (c )Explain giving reasons the existence of placental wolf and Tasmanian wolf sharing the same habitat.

The variables x, v, and a have the dimensions of [L],[L]//[T], and [L]//[T]^(2) , respectively. These variables are related by an equation that has the form v^(n)=2ax , where n is an integer constant (1, 2, 3, etc.) without dimensions. What must be the value of n, so that both sides of the equation have the same dimensions? Explain your reasoning.
