CBSE Class 8 - Mathematics - Factorisation - NCERT Exercise (14.2)

Factorisation

NCERT Exercise 14.2

Q1: Factorise the following expressions.

(i) a² + 8a + 16

(ii) p² − 10p + 25

(iii) 25m² + 30m + 9

(iv) 49y² + 84yz + 36z²

(v) 4x² − 8x + 4

(vi) 121b² − 88bc + 16c²

(vii) (l + m)² − 4lm (Hint: Expand (l + m)² first)

(viii) a⁴ + 2a²b² + b⁴


Answer:

(i) a² + 8a + 16 = (a)² + 2 ☓ a ☓ 4 + (4)²

= (a + 4)² [(x + y)² = x² + 2xy + y²]


(ii) p² − 10p + 25 = (p)² − 2 ☓ p ☓ 5 + (5)²

= (p − 5)² [(a − b)² = a² − 2ab + b²]


(iii) 25m² + 30m + 9 = (5m)² + 2 ☓ 5m ☓ 3 + (3)²

= (5m + 3)² [(a + b)² = a² + 2ab + b²]

(iv) 49y² + 84yz + 36z² = (7y)² + 2 ☓ (7y) ☓ (6z) + (6z)²

= (7y + 6z)² [(a + b)² = a² + 2ab + b²]

(v) 4x² − 8x + 4 = (2x)² − 2 (2x) (2) + (2)²

= (2x − 2)² [(a − b)² = a² − 2ab + b²]

= [(2) (x − 1)]² = 4(x − 1)²

(vi) 121b² − 88bc + 16c² = (11b)² − 2 (11b) (4c) + (4c)²

= (11b − 4c)² [(a − b)² = a² − 2ab + b²]

(vii) (l + m)² − 4lm = l² + 2lm + m² − 4lm

= l² − 2lm + m²

= (l − m)² [(a − b)² = a² − 2ab + b²]

(viii) a⁴ + 2a²b² + b⁴ = (a²)² + 2 (a²) (b²) + (b²)²

= (a² + b²)² [(a + b)² = a² + 2ab + b²]

(iv) 2x, 3x², 4

(v) 6abc, 24ab², 12a²b

(vi) 16x³, −4x², 32x

(vii) 10pq, 20qr, 30rp

(viii) 3x²y³, 10x³y², 6x²y²z

Answer:

(i) 12x = 2 ☓ 2 ☓ 3 ☓ x

36 = 2 ☓ 2 ☓ 3 ☓ 3

The common factors are 2, 2, 3.

And, 2 ☓ 2 ☓ 3 = 12

(ii) 2y = 2 ☓ y

22xy = 2 ☓ 11 ☓ x ☓ y

The common factors are 2, y.

And, 2 ☓ y = 2y

(iii) 14pq = 2 ☓ 7 ☓ p ☓ q

28p²q² = 2 ☓ 2 ☓ 7 ☓ p ☓ p ☓ q ☓ q

The common factors are 2, 7, p, q.

And, 2 ☓ 7 ☓ p ☓ q = 14pq

(iv) 2x = 2 ☓ x

3x² = 3 ☓ x ☓ x

CBSE Class 11 - Biology - Chapter 2 - Biological Classification (Q and A)

CBSE Class 11 

Biology  

Chapter 2 - Biological Classification

NCERT Chapter Solutions

Q1: Discuss how classification systems have undergone several changes over a period of time?

Answer: The classification systems have undergone several changes with time.

① The first attempt of classification was made by Aristotle. He classified plants as herbs, shrubs, and trees. Animals were classified on the basis of presence or absence of red blood cells. This system of classification failed to classify all the known organisms.

② Linnaeus gave a two kingdom system of classification i.e. kingdom Plantae and kingdom Animalia. However, this system did not differentiate between unicellular and multicellular organisms and between eukaryotes and prokaryotes. Thus a large number of organisms could not be classified merely under the two kingdoms.

③ Later a five kingdom system of classification was proposed by R.H Whittaker in 1969. On the basis of characteristics, such as cell structure, mode of nutrition, presence of cell wall, etc., five kingdoms, Monera, Protista, Fungi, Plantae, and Animalia were formed.

④ Later Monera was divided further into Archaebacteria and  Eubacteria because Archaebacteria were different from bacteria in terms of different type of cell wall structure.


Q2: Who is known as Father of Taxonomy? Name the book he published on taxonomy. What's his the greatest contribution in naming species.

Answer: Linnaeus. In 1758 he published his famous book systema naturae. His greatest contribution to taxonomy was the use of binomial nomenclature for all species of animals and plants


Q3: State two economically important uses of:

(a) Heterotrophic bacteria
(b) Archaebacteria

Answer:
(a) Uses of Heterotrophic bacteria

• Commercial and Domestic Use: They (Lacto bacillus) help in the production of curd from milk.
• Decomposers that help in the formation of humus.
• Medicinal use: Many antibiotics are obtained from some species of bacteria.
• Nitrogen Cycle: Many soil bacteria help in fixation of atmospheric nitrogen.

(b) Uses of Archaebacteria

• Live in guts of  ruminant animals such as cows and buffaloes and they produce methane anaerobically (biogas) from the dung of these animals.
• Methanogens are also involved in the formation of biogas and sewage treatment.

Q4: What is the nature of cell-walls in diatoms?

Answer: The cell wall of diatom is made of silica. It consists of two thin overlapping shells that fit into each other such as a soap box with lids. When the diatoms die, the silica in their cell walls gets deposited in the form of diatomaceous earth. This diatomaceous earth, being gritty, is used in polishing, filtration of oils and syrups.


Q5: Name the algae which is a source of iodine.

Answer: Brown algae called kelps, specially from species of Laminaria.

The Living World

Class – XI - Biology - NCERT Chapter 1 Solutions

Question 1: Why are living organisms classified?

Answer:

Classification helps us understand biodiversity better way. Biodiversity have direct and indirect economic benefits to humans as well as to our ecosystem. Systematic study of such biodiversity is essential to better understand the inter-relationships in our ecosystems. Following are the needs to classify them:

① Plants and animals have valuable genetic variation information. It will help us understand the ways evolution take place.

② Humans often benefits from plants and animals in different ways. Systematic study will help exploring other potential benefits.

③ Certain species warn us of imbalances in our ecosystem. e.g. white-rumped vultures became almost extinct because of use of drug brufen (diclofenac) in domestic animals. When vultures ate these dead animals, it led to their kidney failures. Systematic study of the organisms would help in restoring the balance in their ecosystems.

④ Plants and animals have been the inspiration for technology and engineering design. e.g. SONARS and RADARS work on the same acoustics principles as used by bats. Classification will help us revealing such more inspirations.

⑤ It is estimated that the Earth has almost 8.8 million animal, plant, and fungi species, but we’ve only discovered less than a one fourth of this. A large variety of plants, animals, and microbes are found on earth. All these living organisms differ in size, shape, colour, habitat, and many other characteristics. Classification gives a system for identification of known and unknown organisms.


Question 2: Why are the classification systems changing every now and then?

Answer: In the last few hundred million years, plants and animals have undertaken an epic evolutionary journey that has altered the very make-up of the planet. Millions of plants, animals, and microorganisms are found on earth. Many of these have been identified by the scientists. While many new species are still being discovered around the world.

Another reason is that scientists started classifying organisms on the basis of evolutionary relationships rather than solely on the basis of similarities in physical traits.

Therefore, to classify these newly discovered species and finding new basis of classification, new systems of classification have to be devised every now and then. This creates the requirement to change the existing systems of classification.


Question 3: What different criteria would you choose to classify people that you meet often?

Answer: To classify people we often meet, we try to categorise in an ordered fashion.

① To begin with we classify them based on gender. It results in the formation of two major groups- boys and girls.

② Each of these two groups can be further classified on the basis of the blood relatives, distant relatives, friends, knowns and strangers.

③ Finally each individual be identified by its name (first name and sir name)


Question 4: What do we learn from identification of individuals and populations?

Answer:
① It helps in studying characteristics of an individual or its entire population.
② It helps in identifying similarities and dissimilarities among the individuals of same kind or between different types of organisms.
③ It helps the scientists find basis to classify organisms in various categories.
④ It helps us finding the relation between the individuals (or its population) with the ecosystem (Biotic and Abiotic factors).
