Because in human beings body cells are not in direct contact of external environment

Bhoomi Sharma 5 years, 4 months ago

In multicellular organism the body of living is not in direct contact with the surroundings so diffusion is unable to meet the needs of that organism.

Gaurav Seth 5 years, 4 months ago

Human beings are multicellular organisms having a complex body structure. The oxygen requirement in multicellular organisms cannot be met by diffusion because- 
1) Diffusion is a slow process.

 

2) In multicellular organisms, the cells are not in direct contact with the outside environment as in unicellular organisms.

Therefore, in human beings, there are specialized tissues and organs that help to meet the oxygen requirements of the body.

Prudential Reasons: First, power sharing is good because it helps to reduce the possibility of conflict between social groups. Since, social conflict often leads to violence and political instability, power sharing is a good way to ensure the stability of political order. Imposing the will of majority community over minority community may look good in the short run but in the long run it undermines the unity of the nation.

Moral Reason: Power sharing is the very spirit of democracy. A democratic rule involves sharing power with those affected by its exercise, and who have to live with its effects. People have a right to be consulted on how they are to be governed. A legitimate government is one where citizens through participation acquire a stake in the system.

भूमिका-आज का युग विज्ञान का युग है। आज के वैज्ञानिक युग ने मनुष्य के जीवन में बहुत ही प्रभाव उत्पन्न किया है। आज मनुष्य के जीवन में जितनी भी गतिविधियां हो रही है वह सभी विज्ञान की वजह से ही संभव हो पाई है। आज के समय में पुराने रहस्य को भी खोज लिया गया है । आज विज्ञान की वजह से ही आकाश की ऊंचाइयों से लेकर पाताल की गहराइयों को नापना संभव हो पाया है। मनुष्य ने जो प्रगति की है उसका इतिहास इस बात का साक्षी है कि वह किसी समय जानवरों का जीवन जीता था। गुफाओं में रहता था कच्चा मांस और फल सब्जियां खाता था, पेड़ों और पौधों की पत्तियों और छालों को कपड़ों की तरह पहनता था। धीरे-धीरे उसने आग लगाना सीखा और वहां से वह निरंतर आगे बढ़ता चला गया और आधुनिक युग में बहुत आगे बढ़ता चला गया। विज्ञान की वजह से मनुष्य जीवन हर तरह से बदल गया है। विज्ञान की वजह से ही आज मनुष्य इतनी ऊंचाइयों पर पहुंच गया है। विज्ञान का अर्थ- विज्ञान का अर्थ होता है विशिष्ट ज्ञान। अर्थात किसी विषय या वस्तु के बारे में विशेष और व्यवस्थित ज्ञान होना। किसी के पास विशेष ज्ञान होता है तभी विशेष काम किए जाते हैं। विज्ञान शब्द साहित्य और दर्शन के क्षेत्र में भी अर्थ दे सकता है क्योंकि किसी भी विषय का वशिष्ठ ज्ञान होना ही ज्ञान कहलाता है।

UNDER globalisation, particularly after 1990, the farmers in India have been exposed to new challenges. Despite being an important producer of rice, cotton, rubber, tea, coffee and spices our agricultural products are not able to compete with the developed countries because of the highly subsidised agriculture in those countries. Today, Indian agriculture finds itself at the cross roads. To make agriculture successful and profitable, proper thrust should be given to the improvement of the condition of marginal and small farmers.

They don't intersect each other because if they intersect then the compass needle will show 2 different directions... Which is considered impossible....

Yogita Ingle 5 years, 4 months ago

The two magnetic field lines do not intersect each other because if they do it means at the point of intersecting the compass needle is showing two different directions which are not possible.

Radius of the circle = 32 cm

Draw a median AD of the triangle passing through the centre of the circle.
⇒ BD = AB/2

Since, AD is the median of the triangle

∴ AO = Radius of the circle = 2/3 AD

⇒ 2/3 AD = 32 cm

⇒ AD = 48 cm
In ΔADB,

<a href="https://3.bp.blogspot.com/-gsz4sf7No4w/VYwFPSkyvbI/AAAAAAAABA4/6QBibJ98sAw/s1600/ch12-class10-maths-area-related-to-circles-6.png" rel="nofollow" target="_blank"></a>

By Pythagoras theorem,

AB= AD2  + BD2 

⇒ AB= 482  + (AB/2)2

⇒ AB= 2304  + AB2/4
⇒ 3/4 (AB2) = 2304

⇒ AB= 3072

⇒ AB = 32√3 cm
Area of ΔADB = √3/4 × (32√3)cm= 768√3 cm2
Area of circle = π R2 = 22/7 × 32 × 32 = 22528/7 cm2

Area of the design = Area of circle - Area of ΔADB

                              = (22528/7 - 768√3) cm2
