The DNA copying which is not perfectly accurate in the reproduction process results in variations in populations for the survival of species. If the variation are more drastic then the DNA will not be able to function properly leading to the death of the cell.

Evacuation means exiting a facility as directly and safely as possible. Evacuation is appropriate when conditions inside a structure pose a threat to the health and safety of building occupants and leaving the facility is safer than remaining inside of it.

Prove √3 is irrational. It is given in the text. And then, since the difference between a rational and an irrational number is always irrational, 5 - √3 is irrational.

Given √2 To prove: √2 is an irrational number. Proof: Let us assume that √2 is a rational number. So it can be expressed in the form p/q where p, q are co-prime integers and q≠0 √2 = p/q Here p and q are coprime numbers and q ≠ 0 Solving √2 = p/q On squaring both the side we get, =>2 = (p/q)2 => 2q2 = p2……………………………..(1) p2/2 = q2 So 2 divides p and p is a multiple of 2. ⇒ p = 2m ⇒ p² = 4m² ………………………………..(2) From equations (1) and (2), we get, 2q² = 4m² ⇒ q² = 2m² ⇒ q² is a multiple of 2 ⇒ q is a multiple of 2 Hence, p, q have a common factor 2. This contradicts our assumption that they are co-primes. Therefore, p/q is not a rational number √2 is an irrational number.

Any root of imperfect square is an 'irrational number'. As '2' is not a perfect square(i.e.4,9,16....) so root of it is surely irrational.

The four major forms of power sharing in modern democracies are :- 1) Power sharing between different organs of govt (LEGISLATURE, EXECUTIVE, JUDICIARY) = also called HORIZONTAL power sharing or system of checks and balances. Eg :- "Seperation of power" in Indian Constitution. 2) Power sharing between different tiers of govt = also called VERTICAL power sharing or federal system. Eg :- India (Union list, state list, concurrent list). 3) Power sharing between different social groups = Eg :- Reserved constituencies. 4) Power sharing between political parties, pressure groups, interest groups and movements = Elections, NDA UPA and Left front in India.

In exothermic heat is released whereas in endothermic heat is absorbed

Pankaj Kumar Patel 4 years, 5 months ago

Reaction which produce heat are called exothermic reactions . For example All combination reaction are known as exothermic reactions. Reaction in which absorb heat are called endothermic reactions.for examples all decomposition reaction are known as endothermic reactions.

Adithya Dev A 4 years, 5 months ago

Reaction which involve release of heat are called exothermic reactions. All combination reactions are considered to be exothermic in nature. Eg :- C (s) + O2 (g) ----> CO2 (g) + Δ. Reactions which involve absorption of heat are called endothermic reactions. All decomposition reactions are considered to be endothermic in nature. Eg :- NaHCO3 (s) --Δ--> Na2CO3 (aq) + H2O (l) + CO2 (g).

Reflection Refraction
This phenomenon usually occurs in mirrors. This phenomenon usually occurs in Lenses.
Reflection can simply be defined as the reflection of light when it strikes the medium on a plane. Refraction can be defined as the process of the shift of light when it passes through a medium leading to the bending of light.
The light entering the medium returns to the same direction. The light entering the medium travels from one medium to another.
Considering the light waves, they bounce from the plane and change direction. The light waves pass through the surface while simultaneously change from medium to medium.
The angle of incidence of the light is equal to the angle of reflection. The angle of incidence is not equal to the angle of reflection.

Adithya Dev A 4 years, 5 months ago

REFLECTION = phenomenon of bouncing back of light to the same medium after striking a surface. Occurs in the case of MIRRORS. No dependence on optical density of a medium. REFRACTION = phenomenon of bending of light rays as they move obliquely from one medium to another with different optical densities. Occurs in the case of lenses. Depends on optical density of the pair of media.
