Given that the galvanometer has a coil of resistance, G= 60Ω 
And it shows a full scale deflection when current I=1.0A is passed through it. 
And we know that a galvanometer can be converted into an ammeter by connecting a resistor in parallel to the galvanometer coil. 
Here , G = 60 Ω , I_g= 1A, I = 5A and we need to find the value of R 
I_gG = (I – I_g)R 
Or R = I_gG/(I – I_g) 
By putting the respective values R becomes 
R = 15Ω

Maxwell found wave theory of light and found out that light is transmitted in the form of electromagnetic waves. Electromagnetic waves transmit with same velocity equals to that of the light. Electromagnetic waves do not require any medium for propagation.

Emulsion is widely used in food industry (mayonnaise, milk). They have medical and metallurgical applications. Digestion of fats in intestine occur with help of emulsion.

Adsorption process is exothermic hence adsorption decrease with increase in temperature.

The general formulae of Langmuir adsorption isotherm is 
Θ=K[X]/1+K[X] 
For very low concentration of the gas, 1>>>>K[X] and hence, 1+K[X]=1
∴θ=K[X]/1=K[X]

All the tissue outside the vascular cambium constitutes of Bark.  Various kinds of cell layers that constitute the bark are Periderm that includes Phellogen, Phellem and Phelloderm, primary cortex, Pericycle, Primary and secondary Phloem. These all tissue are present outside the vascular cambium. The bark is formed early in the season is called early or soft bark and thus formed the ends of the season is called late or hard bark.

• Thus, Bark excludes the term Secondary cortex

Atactostele is the type where vascular bundles are scattered. Monocot stems show this feature. Hence the correct answer would be maize.

Root endodermis has casparian strips in the form of suberin depositions of the radial and inner walls of the cells. It is a feature of the root tissue system.

Autogamy is refers to self-pollination where pollination occurs within the same flower. Self-pollination takes place in cleistogamous flowers where anther and stigma lie very close to each other. In homogamy, the pollen is shed at the same time when the stigma becomes receptive resulting in intra floral self-pollination. In bud-pollination, stigma and pollens ripen at the same time inside the bud resulting in self-pollination.

In dicliny condition, flowers are unisexual bearing either stamens or pistils. Fertilisation occurs in these flowers by cross pollination.
