The Smooth endoplasmic reticulum is involved in the synthesis of lipids. The rough endoplasmic reticulum synthesizes proteins, Golgi apparatus synthesizes complex sugars and plastids are involved in the synthesis of carbohydrates through photosynthesis.

Following his rescue which was a major media event, both his legs had to be amputated knee down.

D. Plasma membranes contain chitin sugar in plants.

 Rest all the statements are true. Plasma membrane contains cellulose sugar in plants and not chitin.

i) Substances like CO₂ and water move in and out of the cell via the phenomenon of diffusion and osmosis respectively.

 ii) Gases like CO₂ are very small and hence can easily diffuse through the plasma membrane. However, the concentration of such gases on the inside and outside of the cell plays a very important role in their movement. Gases move from a region of higher concentration to a region of lower concentration. 

iii) Generally, the concentration of CO₂ inside the cell is higher than the outside. This makes the CO₂ diffuse from the inside of the cell to the outside. When the concentration of CO₂ becomes higher on the outside, the CO₂ simply diffuses from the outside of the cell to the inside. 

iv) In case of water, the movement occurs as a result of osmosis. Water moves from a region of lower solute concentration to a region of higher solute concentration.

 v) When concentration of water is more on the outside of the cell, the water will move from the outside to the inside of the cell. This occurs as the inside of the cell has less water than the outside but has more concentration of solutes.

The cell membrane is selectively permeable and regulates the movement of substances in and out of the cell. 

Movement of CO₂: CO₂ is produced during cellular respiration. Therefore, it is present in high concentrations inside the cell. This CO₂ must be excreted out of the cell. In the cell’s external environment, the concentration of CO₂ is low as compared to that inside the cell. Therefore, according to the principle of diffusion, CO₂ moves from a region of higher concentration (inside the cell) towards a region of lower concentration (outside the cell). Similarly, O₂ enters the cell by the process of diffusion when the concentration of O₂ inside the cell is low as compared to its surroundings. 

Movement of water: Water moves from a region of high concentration to a region of low concentration through the plasma membrane. The plasma membrane acts as a semi-permeable membrane, and this movement of water is known as osmosis. However, the movement of water across the plasma membrane of the cell is affected by the amount of substance dissolved in water.

Some substances like CO₂
(Which is cellular waste and requires to be excreted out by the cell) accumulates in high concentrations inside the cell. In the cell’s external environment, the concentration of CO₂ is low as compared to that inside the cell. As soon as there is a difference of concentration of CO₂ inside and outside a cell, CO₂ moves out of the cell, from a region of high concentration, to a region of low concentration outside the cell by the process of diffusion. Similarly, O₂ enters the cell by the process of diffusion when the level or concentration of O₂ inside the cell decreases. Thus diffusion plays an important role in gaseous exchange between the cells as well as the cell and its external environment.

A cell performs a variety of functions such as 

(i) Synthesis of complex molecules and their breakdown, 

(ii) Production of energy, 

(iii) Secretion of certain substances, etc.. 

These activities of the cell are performed by different cell organelles. These organelles are enclosed by membranes. To understand the functioning of the cell, it is necessary to know briefly about the structure of cell organelles.

A Cleanliness Drive

Dear Friends,

Our college’s N.S.S. unit has undertaken a cleanliness drive in our village. It is disappointing to see that there is lack of hygiene and sanitation everywhere around us. The disturbing facts of hospitals, overflowing dust cans, spreading epidemics etc. indicate the aim of our unit.

I would like to present the statistical information about the people who have been hospitalized due to water-borne and air-borne diseases. Their number has increased by 32 % and it is really unfortunate. The overflowing dust-cans give rise to high degree of pollution. We submitted a petition to the commissioner but he neglected it. So we have taken the responsibility upon ourselves. We will clean the village and set a fine example for the rest.

As you know, rainy season is approaching next month and our drainage system is too weak to pass the rain-water properly and it can spread epidemics in the village. Hence, we need to act soon. It is not only the responsibility of the civic authority but also ours. And I hope, all of you will support us in this ideal campaign.

Thank you!

At any given time, though, this cheerful Kiwi is as short as 2 cms. compared to what he used to be till that perilous November in 1982.

The cytoplasm is the fluid content inside the plasma membrane. It is a jelly like viscous substance occupying entire cell except the nucleus. It also contains many specialized cell organelles that perform a specific function for the cell.

Differences between Prokaryotic cell and Eukaryotic cell

After both the legs of Mark Inglis were amputated knee-down in November 1982, he was fitted with prosthetic legs, which perhaps made his actual height shorter by 2 cm.

Cytoplasm is the luid content inside the cell membrane. It contains the specialized cell organelles that play important functions in the cell.

Mark Inglis playfully said that it all (climbing) began with him being bad at rugby because, in 1970’s New Zealand, if one was bad at the game, one could do nothing except climbing.

Sum of given ratios = 2 + 5 = 7 

Total profit = Rs. 35,000 

Talisma’s share = (2/7) x 35,000 = Rs. 10,000 

Gurumit’s share = (5/7) x 35,000= Rs. 25,000

Correct answer is

(B) 3 : 2

Correct answer is

(D) Rs. 8,333.33

Constitution is a fundamental document to both the ruler and the ruled because it defines the powers of the three organs an the powers ofthe legislature against the cilizens. It is dealing with fundamental rights also.

Ambedker considers public agitation in free India as unconstitutional because the right to rebellion is recognised against a government with out people’s consent it should be a dictatorship such agitations invariably result in the loss of lives and Public property.

The social welfare Department provide the following facilities. Under Employment and Training scheme 

1. Navachethana is a scheme for imparting training of unemployed SC youths from 1996 – 97 onwards.

2. Incentive scholarships to I to IV students and high school going girls.

All people including Scheduled castes should be given equal opportunities to prove themselves. No legal bars exist for self-expression or self – advancement. They can enroll in institutes ofhigher learning and public serirces. They can prove themselves by participating and acquiring all these positions of responsibility.

Since Independence, members of the scheduled castes have found doors opened to them. No legal bars exist for self – expression or self – advancement. They can enroll themselves in institutes of higher learning and enter public services. They occupy high offices of state and center. They also compete for the post of judges, ambassadors and governors. They have acquitted themselves creditably in all these positions of responsibility.

c. fundamental

Dr. Ambedkar had talented skill in the field of law and legislation. He had a foresighted vision of Social Justice. Above all, he had succeeded in his own campaigns against social injustice. From all points of view, he deserved person to choose as the law minister. Therefore Nehru chose him as the first law minister of free India.

a) They were Mahatma Gandhiji. and Dr. B.R. Ambedker.

b) The revolution referred here is repudiated (means deny) the caste system and to proclaim the oneness of the Hindu community.

c) Gandhiji brings the revolution by reminding the higher castes of their duty towards depressed. Babasaheb did the same by reminding the depressed, classes about their inherent rights to equality with the higher and powerful costes.

Indian National congress and Ambedkar as the chairman .

Nehru described Dr. Ambedker as ‘a symbol of revolt’ because he raised a voice against the discrimination against scheduled caste which had suffered for so long time in the part.

The two man made causes of deforestation are land required for agriculture and urbanisation.

The two natural cause of deforestation are flood and wildfire.

As a chairman of the Drafting committee, Dr. Ambedkar took many examples and experiences of other nations. He considered the need of our own brothern (society) he laid the points step by step. Other luminaries also helped in his work. But he worked a lot. He had the rare gift of most complicated legal concepts into the simple language which can also be understood by common people. So he was rightly called “Pilot”.

Ambedkar was very fond of reading books from his childhood. Throughout his life, he read books. Wherever he went he bought books. He had an insatiable thirst for books. He bought 2000 books from Newyork and 32 boxes of books from London. This shows that he was a voracious reader.

Deforestation is the removal of a forest or strands of trees where the land is thereafter converted to a non-forest use. 

Examples: of deforestation include conversion of forestland to farms, ranches, or urban use.

The conversion of forests into agricultural plantations is a major cause of deforestation. The increase in global demand for commodities, such as palm oil and soybeans, are driving industrial-scale producers to clear forests at an alarming rate. Livestock ranching and forest clearing for livestock ranching is another contributor to deforestation.

While he was in the USA, the 14th amendment of the constitution of the USA gave freedom to the Black American. It drew his attention. The situation for the depressed classes in India had also faced the same problem. At that time Mahatma Phule worked for a classless society and Women’s upliftment. Ambedkar had influence from both the incidents. So he had decided to use his time and talent to improve the conditions of depressed classes.

B. snakes 

Snakes killing can increase the number of rodents. When a number of rodents increase they eat away and destroy the crops and hence cause loss in the production of grains.

The Desertification is a land degradation in which relatively dry area of land becomes increasingly arid, typically losing its bodies of water and vegetation and wildlife.

Agriculture, animal husbandry, and groundwater pumping/depletion, are all significant contributors to the process.

C. deforestation 

Deforestation leads to increase in the floods as rain water is washed away into rivers. As level of water in rivers and eventually increases it leads to flooding of lowlying areas. In addition, the increased greenhouse effect due to deforestation leads to high temperature and melting of snow. This agains increases the water level in rivers and flooding of low-lying areas coastal areas.

(c) It is meant to conserve both, the biodiversity and the culture of that area. 

(a) its population is diminishing 

c.  Dr.B.R. Ambedkar

(d) Conversion of fertile land into a desert.

Dr. Kotnis once served as Dr. Bethune International Peace Hospital’s doctor. He took over the post of the first President of the Bethune International Peace Hospital after Dr. Norman Bethune passed away. He worked as a lecturer earlier for sometime in the military area at the Dr. Bethune Hygiene School.

Metals are present in metallic minerals, while they are absent in non-metallic minerals.

Ferrous minerals contain iron ore, while non-ferrous minerals do not contain iron ore.

one example of a ferrous mineral is Iron.

Diamond is the hardest mineral.
