Four characteristics of commercial farming in India are

1. High quantities of fertilisers, high yield variety seeds, insecticides and pesticides are used to enhance the productivity of land.

2. The degree and extent of commercialised agriculture varies from region to region. For example, wheat in Punjab is a commercial crop, while in Orissa, it is a subsistence crop.

3. Plantation is also a kind of commercial farming where a single crop is grown over a large area.

4. In commercial farming, crops are grown for earning profits. Some of the cash crops are tea, coffee, rubber etc.

Slope between (p+1,p), (p, p+1) = slope between (p, p+1), (p-1,p-2) (p+1-p)/[p-(p+1)] = [(p-2)-(p+1)]/(p-1-p) 1/-1 = -3/-1 -1 = 3

  • Transport of materials is necessary in both plants and animals as every cell needs a regular supply of nutrients and oxygen for releasing energy through respiration. 
  • The food that we eat is broken down into smaller components to be absorbed by the cells. The oxygen that we inhale is also transported to all the cells of the body. Our body also requires a constant removal of waste from the body.

Through the columns of your reputed newspaper, I wish to draw the attention of the general public towards the large number of accidents taking place especially in the metropolitan cities. The reason for this can be numerous, the foremost being the thrill of speed.

1. Ammeter is used to measure the current in a circuit and it should always be connected in series.
2. Resistance means the obstruction caused to the movements of electrons.
3. If resistance is more, current will be less.
4. So, if ammeter has a high resistance than the current measured will be quite less as compared to actual current which is undesirable.
5. If a  ammeter has zero resistance , then we will get exact current in the circuit.
6. But such thing is not possible as every material in this world has some internal resistance.

Reaction with
Oxygen

Metal + Oxygen→Metal oxide
4Na(s) + O2(g) →2Na2O(s)
4Al(s) + 3O2(g) →2Al2O3
Metals form basic oxides
Zn and Al form amphoteric oxides (they show the properties of both acidic and basic oxides)
Most of the metal oxides are insoluble in water Some of them dissolve to form Alkali
Na2O(s) + H2O(l) →2NaOH(aq)

Non-metal + Oxygen →Non-metal oxide
C + O2 →CO2
S + O2 →SO2
Non-metals form acidic
oxides
CO and HO2O are neutral oxides(they are neither acidic nor basic in nature)  Non- metal oxides are soluble in water
They dissolve in water to form acids
SO2 + H2O →H2SO3

2

Reaction
with water

Metals react with water to
form metal oxides or metal hydroxide and H2 gas is released.
2Na(s) + 2H2O(l) →2NaOH +
H2(g) + heat

Non-metals do not react
with water, steam to evolve hydrogen gas. Because  Non-metals cannot give electrons to hydrogen in water so that it can be released as H2 gas.

3

Reaction
with dilute
Acids

Metal + Acid →Metal salt + Hydrogen

HCl
Mg(s) + 2HCl(aq)→ MgCl2(aq) + H2(g)
H2SO4
2Na(s) + H2SO2→ Na2SO4(aq) +H2(g)
HNO3
Metal + HNO3→ H2 gas is not displaced.
Reason- HNO3 is strong oxidizing agent.

Non-metals do not react with acids to release H2 gas                  
Reason- Non-metals cannot loose electrons and give it to Hydrogen ions of acids so that the gas is released.
Mn + 2HNO3→ Mn(NO3)2 + H2
H2 gas from HNO3

4

Reaction
with salt solutions

When metals react with salt
solution, more reactive metal will displace a less reactive metal from its salt solution.
CuSO4(aq) + n(s)→ ZnSO4(aq) + Cu(s)

When non-metals react
with salt solution, more reactive non-metal will displace a less reactive non-metal from its salt solution.
2NaBr(aq) + Cl2(g)→ 2NaCl(aq) + Br2(aq)

The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.[1] Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.

? Pranali.A.P ? 5 years, 6 months ago

the reproductive system has four functions: To produce egg and sperm cells To transport and sustain these cells To nurture the developing offspring To produce hormones

The political development of nationalism and the push for popular sovereignty culminated with the ethnic/national revolutions of Europe. ... Napoleon's conquests of the German and Italian states around 1800–06 played a major role in stimulating nationalism and the demands for national unity. In 19th Century, Nationalism played very significant part in the progress of Europe. Because of common national-identity, various small states were united and transformed into a Country, such as Germany and Italy. ... Progress and Development of the concept of modern nation state became easier by French Revolution.
