Which of the following is correct about saturated hydrocarbon? Four bonds between carbon–carbon and general formula CₙH₂ₙ₊₂ carbon–carbon has double or triple bond and general formula CₙH₂ₙ carbon–carbon has single bond and general formula CₙH₂ₙ₊₂ carbon–carbon has single and double bond and general formula CₙH₂ₙ₋₂

(iii) carbon–carbon single bonds and general formula CₙH₂ₙ₊₂

Identify a dependent variable in Ohm's law V = IR.

V (voltage i.e. potential difference) is the dependent variable — its value changes according to the value of I. Here I is the independent variable and R is a constant.

Write a function of RBC.

Hemoglobin in red blood cells carries oxygen from the lungs to all the cells of the body.

Write any one measure to conserve rare birds in Nepal.

Declare wildlife reserves, protected and conservation areas and legally secure their habitats — and strictly prohibit hunting and illegal trade. (A successful example in Nepal is banning the drug diclofenac for vulture conservation and operating 'vulture safe zones' and breeding centres.)

On which principle does Hydraulic brake work?

Pascal's law — In a closed container, an increase in pressure applied to any part of a confined fluid is transmitted undiminished and equally to every part of the fluid.

If Y is a metal, what is its valency in given product of the chemical equation? 2Y + N₂ → 2YN

3 (three). Nitrogen's valency is 3. In the product YN, Y and N are in a 1:1 ratio, so Y's valency is also 3.

Write a difference between roasting and calcination.

In roasting, the ore is heated in the presence of abundant air at a temperature below the melting point (for sulfide ores), whereas in calcination, it is heated in the absence of air or in limited air (for carbonate and hydrated ores).

IVF is a boon for childless couple, why?

Although shampoo and detergents are better cleaning agents, they degrade our environment. Suggest one natural alternative of such chemical cleansers.
