Sugar quickly dissolves in hot water glass and slow in the cold water glass.

Because the water is not stirred by adding sugar in the glass.

S_{n + 3} – 3S_{n + 2} + 3S_{n + 1} – S_n 

= (S_{n + 3} – S_{n + 2}) – 2 (S_{n + 2} – S_{n + 1}) + (S_{n + 1} – S_n) 

= t_{n + 3} – 2t_{n + 2} + t_{n + 1}                           ... (i) 

(∵ t_n = S_n – S_{n – 1})

∵ t_{n + 1}, t_{n + 2}, t_{n + 3} are consecutive terms of an A.P, 

2t_{n + 2} = t_{n + 1} + t_{n + 3}                             ...(ii)

∴ From (i) 

Reqd. Sum = (t_{n + 3} + t_{n + 1}) – 2t_{n + 2} 

= 2t_{n + 2} – 2t_{n + 2} = 0                              (Using (ii))

It conducts water and minerals from the roots to the stem and leaves. It also provides mechanical strength to the plant parts.

• Cells are variously shaped – oval, polygonal or spherical.
• The cell wall is unevenly thickened-thickenings are prominent in the corners, thickening is made of pectin, cellulose and hemicellulose.
• Often the cells contain chloroplasts 
• Intercellular spaces are absent.

When the Dormouse, the Hatter and the March Hare saw Alice coming, they shouted that there was no room (place) on the table to seat anyone.

Three silly remarks made by the characters other than Alice: 

a. I see what I eat – I eat what I see – Hatter 

b. I like what I get – I get what I like – March Hare 

c. I breathe when I sleep -1 sleep when I breathe – Dormouse 

All have a statement and an inverted version of the same. There is no intention of conveying any message. They are spoken for the sake of speaking. However, they sound silly.

Apart from class/school, where else are you likely to find a time table useful.

1. I do what I love. 

2. I love what I do.

If ‘Time’ was my friend, I would want to do a lot of things. I will want to get back to my childhood days. I would go back in time and keep my grandparents and all my near and dear ones (who are no more now) alive.

Five differences between a raven and a writing desk:

c. A raven cannot be used for writing purposes but a writing desk can be used for the same purpose. 

d. A raven can lay eggs but a writing desk cannot. 

e. A raven is natural and a writing desk is manmade.

The function of insulin hormone is to lower the blood sugar level (or blood glucose level). People having severe diabetes are treated by giving injections of insulin.

Urine output is inversely proportional to ADH. If ADH secretion is reduced, it increases the urine output and the osmolarity of blood increases.

(i) Periderm: The cork, cork cambium and secondary cortex collectively form a protective tissue called periderm. In order to increase in girth and prevent rupturing of the outer ground tissues due to the formation of secondary vascular tissues, dicot stems produce a cork cambium or phellogen in the outer cortical cells. Phellogen cells divide on both the outer side as well as the inner side to form secondary tissue. The secondary tissue produced on the inner side of the phellogen is parenchymatous. It is called secondary cortex or phelloderm. Phellogen produce cork or phellem on the outer side. The phelloderm, phellogen and phellem together constitute the periderm.

(ii) The vascular bundles are arranged in the form of ring around the central pit. The xylem bundles are exarch, i.e., protoxylem lies towards the outer side while the metaxylem faces inwards. Phloem bundles alternate with xylem bundles.

Depending upon the time of origin and internal structure, the xylem is of two types: 

(i) Protoxylem: It is first or easily formed xylem. It is made up of small tracheids and vessels, with annular or spiral thickenings. 

(ii) Metaxylem: It is later formed xylem. It consist of larger tracheids and vessels and have reticulate, scalariform and pitted thickenings.

These are large epidermal cells located on the upper epidermis and help to bring about rolling of leaves under scarcity of water. 

Collateral, Conjoint, Open and endarch. 

When Xylem and phloem are arranged on different radii the vascular bundle is termed radial.

The main components of xylem are: 

(i) Tracheids, (ii) Vessels, (iii) Xylem parenchyma, (iv) Xylem fibres. 

(i) Tracheids and vessels are responsible for the conduction of water and minerals because they are elongated tubular channels with wide lumen. 

(ii) Xylem tracheids possesses pits with pores and vessels possess perforated plates through which they are able to conduct water and minerals from one cell to the another.

The multicellular epidermal outgrowths are called trichomes.

When the protoxylem faces the periphery Xylem is described as exarch.

Alice spoke with severity that Hatter should learn not to make personal remarks as it is rude.

Dicot / bengal gram root. 

Hatter remarked that Alice’s hair wants cutting.

Alice sat down in a large arm-chair at one end of the table.

Wildlife means all those naturally occurring animals, plants and their species which are not cultivated, domesticated and tamed.

Wildlife is important for us because

(i) They provide great aesthetic value for human beings. 

(ii) They help in maintaining ecological balance.

i. draw the curtain

ii. had butterflies in my stomach

iii. was relieved

iv. appraise

v. was escorted

vi. are likened.

The March Hare told Alice to have some wine, in an encouraging tone.

Characteristics of a good fuel are.

(i) Higher calorific value 

(ii) Lesser pollution 

(iii) Sustainable for longer period 

(iv) Easily transport

Special invitees, guests, parents, teachers and students were present for the Art Festival.

Alice did not see any wine on the table. Alice looked all around the table, but she found nothing on it except tea.

Music is the pattern of sounds produced by people singing or playing instruments expressing ideas and emotions. Vocal refers to music human voice, which is singing.

The three R's are Reduce, Recycle and Reuse.

Reduce : This means that we should use the resources judiciously and check their misuse. We should save electricity by switching off unnecessary lights and fans. We should save water by repairing leak taps. 

Recycle : This means that we should collect plastic, paper, glass and metal items and recycle this material to make required things instead of synthesising fresh plastic, paper, glass or metal. 

Reuse : This is even better than recycling because it saves the energy which is spent at recycling a product. Things are used over and over again. For example, envelopes can be reused by reversing them.

The three R’s to save the environment are: 

1.  Reduce: Reduce means that we use less of the natural resources by cutting down on those practices which lead to their wastage. For example – we can reduce the wastage of electricity by switching off unnecessary lights and fans. 

2.  Recycle: Recycling means that we should collect the used and discarded items of paper, plastic, glass and metals, and send them to the respective industries for making fresh paper, plastic, glass or metal objects.

3.  Reuse: Reuse means that we should use the same things again. For example plastic jars  in which we buy various food items like Jams, pickles etc, can be used later on for storing things like salt and sugar.

The three types of 'R'are Reduce, Reuse, Recycle. The 3-R's can be followed in the following ways:
-Switch off the fans and bulbs when not in use,
-Reuse of paper, polythene bags, etc.,
-Reduce the wastage of water/paper or any other item.

Exclamatory sentence

a table – subject was set out under a tree – predicate

The table was a large one, wasn’t it.

The programme began with the lighting of the lamp.

1. What a wonderful presentation! 

2. That was indeed a fantastic performance! The compere says the given statements after the programme has ended.

Yes, I think such programmes inspire students. Mark Twain has rightly remarked, “Thousands of geniuses live and die undiscovered – either by themselves or by others. Such programmes help students to get over their fears and also build up their confidence. It also serves as a platform to showcase their hidden talents. Appreciation in the form of award/trophy further encourages them to do even better.

The March Hare and the Hatter were having tea at the table and a Dormouse was sitting between them.

The Chief Guest, Shri Charudatta Diwan gave away the prizes to the prize winners.

The Dormouse was sitting between the March Hare and the Hatter. They both were using the Dormouse as a cushion, resting their elbows on it and talking over its head. So, Alice thought that the dormouse must be uncomfortable.
