Taxonomic keys are tools that help in identification of organisms based on the description of specific characters. e.g. flora (A resource providing information on the taxonomy, nomenclature and descriptive data of newly discovered plants).
Taxonomy includes study of following 4 points:
(1) Identification: Identification of living organisms
(2) Nomenclature: Nomenclature of living organisms
(3) Classification: Classification of living organisms in groups
(4) Affinities: Study of inter relationship between living organisms

The red colour deviates the least.
Violet colour deviates the most.
This is because red has largest wavelength while violet has the shortest wavelength

Here, R0=1.1×10−15m,A=16
R=R0A1/3
=1.1×10−15(16)1/3=1.1×10−15×2.52
=2.57×10−15m

Poor rag-pickers like Saheb spend the early years of their lives looking for gold in garbage dumps. The parents of these street children have no fixed income. They wage war against poverty and hunger. They have no dreams except finding the means of survival. Garbage to them is gold. It is the source of their daily bread and provides a roof over their heads. He ends up as a servant at a tea-stall and loses his freedom.
Mukesh, the son of a poor bangle-maker of Firozabad, has a dream of becoming a motor mechanic. He wants to learn to drive a car. He thinks of joining a garage to fulfil his dream. He knows that the garage is far away, yet he has decided to walk. He realises the reality and is willing to overcome the obstacles. His daring to rise and decision to get free from the trap laid by vicious moneylenders and middle men arouse a sense of hope.Deprived of education, proper food and upbringing, these children are forced into labour early in life.

Rutherford passed beams of alpha particles through a thin gold foil to observe the atom and noted how the alpha particles scattered from the foil.
Observations of Rutherford's alpha ray scattering experiment:
1.Most of the α-particles passed straight through the gold foil without any deviation.
2. Some of the α-particles were deflected by the foil by some angles.
3.Interestingly one out of every 12,000 alpha particles appeared to rebound
Conclusion of Rutherford's scattering experiment:
1.Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected.
2. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
3. A very small fraction of α-particles were deflected by very large angles, indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.

1. The water vapour content of the air
This is produced by normal living activities such as washing, cooking, bathing, etc., and can be controlled by the use of extractor fans, cowlings, and ventilation at appropriate places.
2. Inside room temperature
This can be controlled to some extent by replacing single glazing with energy-efficient double or triple glazing, thereby maintaining a higher surface temperature of the glass on the room side.
3. Outside temperature
This cannot be controlled, but its effect on the inside room temperature can be reduced by the installation of energy efficient double or triple glazing.

Let us rewrite (102)3 as (100+2)3
Now using the identity (a+b)3=a3+b3+3ab(a+b), we get
(100+2)3=1003+23+[(3×100×2)(100+2)]
=1000000+8+(600×102)
=1000000+8+61200
=1061208
Hence, (102)3=1061208

Kirchhoff’s First law: Junction law
- Junction Law is also known as Kirchhoff’s First Law.
- It states that at the junction,sum of current entering the junction is equal to the sum of current leaving the junction.
- Junction is any point in the circuit.
Kirchhoff’s Second law: Loop law
- Loop law is also known as Kirchhoff’s Second Law.
- It states that in a closed loop,algebraic sum of Emfsis equal to the algebraic sum of product of resistances and respective currents flowing through them.
- Consider a simple circuit havingEmfs = E1 and E2; R1 and R2 =resistances; current =I1 and I2.
- Then according to this law : E1+E2=I1R1+ I2R2

Sustainable development is the prudent and judicious use of resources in such a way that even future generations are able to use it.
Sustainable development is essential for economic development as we have limited quantity of resources. Firstly, the development and growth of the country will be hampered if the present limited resources are totally exhausted.
Secondly, the exhaustion of natural resources will endanger the lives of humans and many species if we do not follow the principle of sustainable development. For example, if water is overutilised and wasted, then it will not be replenished by the rains. We need to keep the stock of natural resources for future use too.

Lenz’s law
- According to Lenz’s law:-The polarity of the induced emf is such that it tends to produce induced current in such a direction that it opposes the change in magnetic flux that produced it.
- The (-) ive sign in given equatione= (-) (dΦ/dt)tells about the direction.
- According to Faraday’s law whenever there is change in the magnetic flux, emf is induced, as aresult there will be induced current.
- According to Lenz’s law the direction of the induced current will be such that it opposes the change in the magnetic flux.
