HRD Minister Ramesh Nishank announced a major CBSE syllabus reduction for the new academic year 2020-21 on July 7 which was soon followed by an official notification by CBSE on the same.

Considering the loss of classroom teaching time due to the Covid-19 pandemic and lockdown, CBSE reduced the syllabus of classes 9 to 12 with the help of suggestions from NCERT.

Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.  Therefore, the presence of life processes is a fundamental criterion that can be used to decide whether something is alive or not.

Evidence which can ensure something is alive or not

• Shape and Dimension
• Reproduction
• Growth
• Cellular structure
• Metabolism
• Movements
• Self-regulations
• Variation
• Co- ordination
• Definite life cycle
• Death

Example – Movements are fast in most animals but motions in plants are generally slow.

The parting scene between Tricki and Mrs. Pumphrey was quite melodramatic. As soon as the narrator told her the dog needed to be hospitalized for a few days, she swooned. She was reluctant to send Tricki to the narrator’s hospital.  

However, the narrator was firm on it; as he took the sick dog to his car, Mrs. Pumphrey sent all her staff with Tricki’s luxuries to be carried to the hospital. The luxuries included: Tricki’s day bed, night bed, favourite cushions, toys and rubber rings, breakfast bowl, lunch bowl, supper bowl.  

As the narrator moved away with the dog, Mrs. Pumphrey cried, and the entire staff was in tears.

USA, Switzerland and Australia are examples of coming together federations.

India, Belgium and Spain are examples of holding together federations.

'Coming together' federation is nothing but independent states coming together on their own to form a bigger state or country.

Holding together federation is nothing but the division of powers between the states of the country and central government of that country.

All the constituent States usually have equal power and are strong vis-à-vis the federal government in coming together federation.

The central government tends to be more powerful vis-à-vis the States in holding together federation.

Catenation : The self linkage is known as catenation. The property of catenation is responsible for the occurrence of innumerable oragnic compounds.

It is the binding of an element to itself through covalent bonds to form chain or ring molecules.

Examples : Carbon is the most common element that exhibits catenation property. That means it can form long hydrocarbon chains and rings like benzene.

Ophthalmoscopy is done as part of a routine physical or complete eye examination. It is used to detect and evaluate symptoms of retinal detachment or eye diseases such as glaucoma. The direct ophthalmoscope allows you to look into the back of the eye to look at the health of the retina, optic nerve, vasculature and vitreous humor. This exam produces an upright image of approximately 15 times magnification. The Large aperture is used for a dilated pupil after administering mydriatic drops.

Ophthalmoscopy, also called funduscopy, is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope .

Metals can conduct electricity because of the free electrons present in it. These free electrons will move in a particular direction ( the direction of the flow of current ) when electricity is passed through it this conducting electricity.

Metal conduct easy because most of the metals will lose electrons , we have already studied the flow of electrons is electricity. Therefore in metals electrons can easily move . So that the metals are good conductor of electricity

Metal conduct electricity because it is a good Conductor of electricity

the close packing of the metal ions in the lattice the delocalised electrons can carry kinetic energy through the lattice. Picture 1.4 A cool lattice. If we heat the left hand end, then the energy will be carried along by conduction.Ionic vibrationsThe positive metal ions in a metal structure are packed closely together in a symmetrical geometric arrangement. They don’t move from their position in the lattice but they are constantly vibrating. If a metal is heated, the positive metal ions vibrate more vigorously. These ions collide with neighbouring ions and make them vibrate more vigorously too. In this way, the energy is passed, or conducted, through the metal.

Substances conduct electricity because they contain charged particles that are able to move. When a voltage is applied to a metal, the delocalised electrons travel through the lattice structure. The movement of these charged particles forms an electric current.  Electric current is the flow of electrons in a wire. In metals, the outer electrons of the atoms belong to a 'cloud' of delocalised electrons. They are no longer firmly held by a specific atom, but instead they can move freely through the lattice of positive metal ions. Metals are good conductors of heat.

Whitman finds that animals have many virtues that men are lacking. They remain very calm,  quiet and satisfied.  They have no worries. That  is why Whitman wants to live with them.

Man are always unhappy and discontented. They keep grumbling. They go mad for material possessions. Animals do none of these things. They  are always happy and contended. They don’t  have to weep over their sins.

Local Govt is also exist in urban areas. In these areas like gram panchayat towns are divided into municipalities and municipal corporation. Municipality and municipal corporation is controlled by representative of people. Head of municipality is municipal chairperson and head of municipal corporation is mayor.

"Organisation of local government bodies in Urban Areas

In common terms, the "Urban" includes Towns, Cities, and Bigger cities. In urban areas, the local government is organized as Municipal Corporation, Municipality, and Nagar Panchayats.

Among the three Municipal corporations is in topmost position in the local government. It receives a major share of finance which has been allocated to the local government. It controls the areas in which population is more than 2-3 lakhs.

Municipality and Nagar Panchayats are in charge of areas with population ranging from 20000 to 100000. It has separate wards and members for this body, which were elected five years once. "

Let’s assume the digit at unit’s place as x and ten’s place as y. Thus from the question, the number needed to be found is 10y + x.

From the question it’s told as, the two digits of the number are differing by 2. Thus, we can write

x – y = ±2………….. (i)

Now after reversing the order of the digits, the number becomes 10x + y.

Again from the question it’s given that, the sum of the numbers obtained by reversing the digits and the original number is 66. Thus, this can be written as;

(10x+ y) + (10y+x) = 66

⇒ 10x + y + 10y + x = 66

⇒ 11x +11y = 66

⇒ 11(x + y) = 66

⇒ x + y = 66/11

⇒ x + y = 6………….. (ii)

Now, we have two sets of systems of simultaneous equations

x – y = 2 and x + y = 6

x – y = -2 and x + y = 6

Let’s first solve the first set of system of equations;

x – y = 2 …………. (iii)

x + y = 6 ………….. (iv)

On adding the equations (iii) and (iv), we get;

(x – y) + (x + y) = 2+6

⇒ x – y + x + y = 8

⇒ 2x =8

⇒ x = 8/2

⇒ x = 4

Putting the value of x in equation (iii), we get

4 – y = 2

⇒ y = 4 – 2

⇒ y = 2

Hence, the required number is 10 × 2 +4 = 24

Now, let’s solve the second set of system of equations,

x – y = -2 …………. (v)

x + y = 6 ………….. (vi)

On adding the equations (v) and (vi), we get

(x – y)+(x + y )= -2 + 6

⇒ x – y + x + y = 4

⇒ 2x = 4

⇒ x = 4/2

⇒ x = 2

Putting the value of x in equation 5, we get;

2 – y = -2

⇒ y = 2+2

⇒ y = 4

Hence, the required number is 10×4+ 2 = 42

Therefore, there are two such possible numbers i.e, 24 and 42.

Given,

 α and ß are the zeroes of polynomial x² - px + q.

In this quadratic equation,

Coefficient of x² ( a ) = 1

Coefficient of x( b ) = -p

Constant term ( c ) = q.

We have,

⇒ Sum of zeroes = -b/a

⇒ α + ß = - ( - p ) / 1

∴ α + ß = p.

⇒ Product of zeroes = c/a

⇒ αß = q/1 = q

Now,

⇒ ( α + ß )² = α² + ß² + 2 αß

⇒ ( p )² = α² + ß² + 2 q

⇒ p² = α² + ß² + 2 q

∴ α² + ß² = p² - 2q
