The insectivorous plants grow in soil which do not contain sufficient nitrogen mineral. These plants (e.g. pitcher plant) are green and carry out photosynthesis to obtain a part of the food required by them. But they do not get the nitrogen from the soil in which they grow. So, insectivorous or carnivorous plants feed on insects to obtain the nitrogen needed for their growth.

On January 1, 1991, the Soviet Union was the largest country in the world, covering some 8,650,000 square miles (22,400,000 square km), nearly one-sixth of Earth’s land surface. Its population numbered more than 290 million, and 100 distinct nationalities lived within its borders. It also boasted an arsenal of tens of thousands of nuclear weapons, and its sphere of influence, exerted through such mechanisms as the Warsaw Pact, extended throughout eastern Europe. Within a year, the Soviet Union had ceased to exist. While it is, for all practical purposes, impossible to pinpoint a single cause for an event as complex and far-reaching as the dissolution of a global superpower, a number of internal and external factors were certainly at play in the collapse of the U.S.S.R.

i) A major step towards decentralisation was taken in 1992. The Constitution was amended to make the third-tier of democracy more powerful and effective.

ii) Rural local government is popularly known by the name panchayati raj. Each village, or a group of villages in some States, has a gram panchayat. This is a council consisting of several ward members, often called panch.

iii) A few gram panchayats are grouped together to form what is usually called a panchayat samiti or block or mandal. The members of this representative body are elected by all the panchyat members in that area. All the panchayat samitis or mandals in a district together constitute the zilla (district) parishad. Most members of the zilla parishad are elected. Members of the Lok Sabha and MLAs of that district and some other officials of other district level bodies are also its members. Zilla parishad chairperson is the political head of the zilla parishad.

Henry's Law is a chemistry law which states that the mass of a gas which will dissolve into a solution is directly proportional to the partial pressure of that gas above the solution.

The relationship between pressure and solubility is guided by Henry's law. 

According to this law, "The mass of a gas dissolved in given volume of the liquid at a constant temperature depends upon the pressure which applied."

Atomic size of insert gases does not affect inertnes because the larger the Noble Gas, the more easily the gas should be oxidized, if only because the valence electrons are farther removed from the nuclear core. Fluorides and oxides of xenon and krypton are pretty routine these days. Argon compounds are much more of a  rara avis ...and these are not something with any prolonged existence.

x = -450 + 327

x = -123

So, other integer is -123.

Socialist means the system under which economic system is controlled and regulated by the government so as to ensure welfare and equal opportunity to the people in a society.

The word socialism means ‘all things to all men’. According to Samuelson, “Socialism refers to the government ownership of the means of production, planning by the government and income distribution”.

The main features of socialist economy are as follows: 

(i) Collective Ownership: In socialism, all means of production are owned by the community, i.e., Government, and no individual can hold private property beyond certain limit. Therefore, it is government who utilises these resources in the interest of social welfare.

(ii) Economic, Social and Political Equality: Under socialism, there is almost equality between rich and poor. There is no problem of class struggle. 

(iii) Economic Planning: Under socialism, government fixes certain objectives. In order to achieve these objectives, government adopts economic planning. All types of decisions regarding the central problems of an economy are taken in the economic plans. There is a Central Planning Authority, who plans for the economy.

The correct option is :(B)

Explanation:

A nuclear reactor coolant — usually water but sometimes a gas or a liquid metal (like liquid sodium) or molten salt — is circulated past the reactor core to absorb the heat that it generates. The heat is carried away from the reactor and is then used to generate steam. 

Control rods that are made of a neutron poison are used to absorb neutrons. Absorbing more neutrons in a control, rod means that there are fewer neutrons available to cause fission, so pushing the control rod deeper into the reactor will reduce its power output, and extracting the control rod will increase it.

A neutron moderator is a medium that reduces the speed of fast neutrons, thereby turning them into thermal neutrons capable of sustaining a nuclear chain reaction involving uranium-235. Commonly used moderators include regular (light) water (roughly 75% of the world's reactors), solid graphite (20% of reactors) and heavy water (5% of reactors). Nuclear fuel is a material that can be 'burned' by nuclear fission or fusion to derive nuclear energy. Nuclear fuel can refer to the fuel itself, or to physical objects (for example, bundles composed of fuel rods) composed of the fuel material, mixed with structural, neutron moderating, or neutron reflecting materials. The most common fissile nuclear fuels are uranium-235 (²³⁵U) and plutonium-239 (²³⁹Pu).

The correct option is : (D)

Explanation:

The “plum pudding model” was put forward by J.J. Thomson in 1904. In this model, the atom is made up of negative electrons that float in a “soup” of positive charge, much like plums in a pudding or raisins in a fruit cake. In 1906, Thomson was awarded the Nobel Prize for his work in this field.

Louise de Broglie suggested that electron exhibits a dual nature. Broglie also got Physics Noble Prize for his theory

In 1913, Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.

Ernest Rutherford published his atomic theory describing the atom as having a central positive nucleus surrounded by negative orbiting electrons. This model suggested that most of the mass of the atom was contained in the small nucleus and that the rest of the atom was mostly empty space
