Mrs Pearson and Mrs Fitzgerald are two contrasting characters. Actually, they are foil to each other. Mrs Pearson is a pleasant looking woman in her forties. She appears to be confused and worried. Mrs Fitzgerald is older. She is heavier and has a ‘strong and sinister personality’. Mrs Pearson is timid and gentle. Mrs Fitzgerald is liberated and bold. She smokes and plays with cards. The two ladies have sharply contrasting voices. Mrs Pearson speaks in a ‘light, flurried sort of tone’. She has ‘a touch of suburban Cockney’. Mrs Fitzgerald has a deep voice. Her accent is Irish.

Mrs Pearson has been reduced to a mere servant in her own house. Her children and husband make her run all the time. She has to dance to their beck and call. Her children Doris and Cyril are spoilt children. They are also selfish and thoughtless. They don’t pay that respect to their mother which she really deserves. Mr George also treats his wife rather indifferently and coldly. Mrs Pearson is condemned to drudgery. Mrs Fitzgerald, on the other hand, is a liberated woman. She is bold and dominating. She enjoys good time and is the mistress of herself and the family.

Mrs Pearson is tender and mild. When Mrs Fitzerald gives a heavy dose to Doris, Cyril and George, she can’t bear it. She asks her to stop the drama at once. She presses her to change back their personalities. Mrs Fitzgerald is firm, solid and result-oriented. She sets all the spoilt members of Mrs Pearson’s family right. She is a better judge of men and matters than Mrs Pearson.

Yogita Ingle 5 years ago (2577571)

Mrs. Pearson

Mrs. Pearson appears to be a timid and confused lady. She is in her forties. She is a devoted housewife. She enjoys serving her husband and  children. She is ignored and made to work throughout the day. In spite of their ill treatment, neglect and exploitation, she loves them all. In fact, for that she endures everything without any murmur or protest. We feel sympathy for her. We wish her to be a little more assertive. However, Mrs. Fitzgerald brings about a change in her personality. She helps her to become more assertive and dominating at the end.

Mrs. Fitzgerald

Mrs. Fitzgerald is quite experienced and smart. She knows some esoteric magic that she learned in the East. She is heavier and has a 'strong and sinister personality'. She is liberated, strong, dominating and bold. She smokes and plays cards. Mrs Fitzgerald has a deep voice. Her accent is Irish. Mrs. Fitzgerald is firm, solid an d result -oriented. She sets all the spoilt members of Mrs. Pearson's family right.

The Bhakti movement was led by Alvars and Nayanars. Alvars are those who worshipped lord Vishnu and Nayanars are those who claimed to be the followers of Lord Shiva. They extensively travelled singing devotional song in the name of their gods. These sects gave a blow to the caste system and Brahmanism by their beliefs and practices.

BHAKTI AND THE STATE

 

1. In the 6th century BCE, there evolved a new form of worship in South India – the bhakti movement. They Focused on the worship of specific deities such as Shiva and Vishnu and were known as Alvars and Nayanars.

 

2. The Bhakti Saints in their compositions opposed Jainisim and Buddhism; As a result, some of the rulers of Southern kingdoms like the Cholas, who supported the earlier Brahmanical traditions, supported Bhakti traditions.

 

3. They made land grants.

 

4. Some of the most magnificent temples were constructed under the patronage of the Chola rulers at Chidambaram, Tanjavur, and Gangaikondacholapuram.

 

5. Bronze sculpture of Shiva, one of the finest specimens of Indian art was also made during this period.

 

6. The Chola kings in order to claim divine support, built temples adored with the image of the Saints.

 

7. The kings also introduced the singing of Tamil Shiva hymns in temples under royal patronage and took the initiative to collect and organise them into a text.

 

8. The Chola ruler, Parantaka I had consecrated metal images of Appar, Sambandar (Bhakti Saints) in a Shiva temple.

 

Since both Alvars and Nayanass were revered by rich Vellala peasants and common people as well, so the Chola rulers tried to claim divine status.

In the story Mothers day, we see the story of a family. This story is set in the 1950s and reflects some of the practices during those times. We see that in the family everyone treats Mrs. Person like a servant and only look for her when they need some work to be done.
This happens because of the negligence on the part of Mrs. Pearson. Since she never opposes such behavior everyone in the family thinks that it is okay for them to treat her in such a way.

Mourad and Aram were cousins and belonged to Garoghlanian tribe which was known for its honesty. Mourad was thirteen and Aram was nine years old. Both longed to ride a horse. But their family was too poor to buy a horse. Both were adventure-loving. Both knew that their family was well known for honesty and right conduct. But Mourad could not help stealing John Byro’s horse. While he had a streak of craziness, Aram was honest and simple-hearted. Mourad was more talented and bolder than Aram. He domesticated the wild horse of John Byro. He repaired the injured wing of a robin bird; he knew how to deal with a horse, and how to soothe a dog. Comparatively, Aram was timid and obedient. Mourad could easily lie to John Byro about the horse. Aram could never do it.

Uncle Khosrove was widely known to be crazy. He was short-tempered and impatient as well. He stopped others from talking by shouting at them. His stock saying was: it is no harm, pay no attention to it. ‘Mourad had got that craziness from Uncle Khosrove.

The unit of ρ is ohm−m(Ωm)

Yogita Ingle 5 years ago (2577571)

Electrical resistivity is the reciprocal of electrical conductivity. It is the measure of the ability of a material to oppose the flow of current. Materials resist the flow of electric current. Some of the materials are better at conducting electric current than the others.

Resistivity is defined as the electrical resistance of a conductor of unit cross-sectional area and unit length. The resistance of any conductor is directly proportional to the length of the conductor and inversely proportional to the area of cross-section of the conductor.

Streamlined shape boat has also streamlined shape because it help to float and swim easily

Chhavi Parmar 5 years ago (10082746)

because of fins

Gaurav Seth 5 years ago (2898529)

The streamlined shape of the fish allows water to flow around it easily and help the fish to move in water. The skeleton of the fish is covered with strong muscles. During swimming, muscles make the front part of the body curve to one side and the tail part swings towards the opposite side. The fish forms a curve. Then, quickly, the body and tail curve to the other side. This makes a jerk and pushes the body forward. A series of such jerks make the fish swim ahead. This is helped by the fins of the tail.

Yogita Ingle 5 years ago (2577571)

Fishes have a streamlined body shape. This shape allows them to move easily in water. When a fish swims in water, the muscles that cover its skeleton cause the front part of the body to curve towards one side. On the other hand, the tail (with fins) curves towards the opposite side.

Digestive system: The system of organs responsible for getting food into and out of the body and for making use of food to keep the body healthy. The digestive system includes the salivary glands, mouth, esophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum.

Yogita Ingle 5 years ago (2577571)

  • The human digestive system consists of the alimentary canal and the associated glands.

Alimentary canal 

  • The alimentary canal begins with an anterior opening – the mouth, and it opens out posteriorly through the ****.
  • The mouth leads to the buccal cavity or oral cavity, which has a number of teeth and a muscular tongue and each tooth is embedded in a socket of jaw bone with a type of attachment called as thecodont.
  • A set of temporary milk or deciduous teeth is replaced by a set of permanent or adult teeth, and the type of dentition is called diphyodont.
  • An adult human has 32 permanent teeth, which are of four different types
  • incisors (I)
  • canine (C)
  • premolars (PM)
  • and molars (M).
  • Arrangement of teeth in each half of the upper and lower jaw in the order I, C, PM, M is represented by a dental formula which in human is 2123/2123.
  • The tongue is a freely movable muscular organ attached to the floor of the oral cavity by the frenulum, and the upper surface of the tongue has small projections called papillae, some of which bear taste buds.
  • The oesophagus and the trachea open into the pharynx.
  • A cartilaginous flap called epiglottis prevents the entry of food into the glottis, which is the opening of the wind pipe.
  • The oesophagus is a thin, long tube which extends posteriorly passing through the neck, thorax and diaphragm and leads to a ‘J’ shaped bag like structure called stomach.
  • The stomach has three major parts
  • a cardiac portion into which the oesophagus opens
  • a fundic region
  • a pyloric portion which opens into the first part of small intestine.
  • Small intestine is distinguishable into three regions
  • a ‘U’ shaped duodenum
  • a long coiled middle portion jejunum
  • a highly coiled ileum.
  • The opening of the stomach into the duodenum is guarded by the pyloric sphincter.
  • Ileum consists of
  • caecum
  • colon
  •  
  • Caecum is a small blind sac from which a vestigial organ called vermiform appendix
  • The colon is divided into three parts
  • an ascending
  • a transverse
  • a descending part.
  • The descending part opens into the rectum which opens out through the ****.
  • The wall of alimentary canal from oesophagus to rectum possesses four layers
  • Serosa
  • muscularis
  • sub-mucosa
  • Serosa is the outermost layer and is made up of a thin mesothelium and some connective tissues.
  • Muscularis is formed by smooth muscles usually arranged into an inner circular and an outer longitudinal layer.
  • The submucosal layer is formed of loose connective tissues.
  • Mucosa is the innermost layer which forms rugae in the stomach and small finger-like foldings called villi in the small intestine.
  • The cells lining the villi produce numerous microscopic projections called microvilli giving a brush border appearance.
