Why WBCs are often called soldiers of the body .give reasons


Posted by Amaya Chauhan (Feb 28, 2017 3:22 p.m.) (Question ID: 2791)

  • Answers:
  • Ans. White blood cells (WBC) are like an army. They patrol your body constantly, on the lookout for attacks from viruses, bacteria, and other infections. If the scouts find a problem, they sound the alarm and the troops swarm to the site of the attack.

    And just like a military is made up of Army, Navy, Marines, and Air Forces, the WBC army also has specialists with names like Neutrophil, Esoniophil, Basophil, Lymphocyte, and Macrophage.

    Each "branch" of the WBC military specializes in fighting different kinds of invaders.

    They provide immunity to our body. They help in fighting against diseases, infections, allergies and foreign particles. These cells keep our body safe and healthy, much like the soldiers of a nation.

Why did human race spread from Africa to other parts of the world?

Posted by Sarthak Chauhan (Feb 28, 2017 2:07 p.m.) (Question ID: 2786)

  • Answers:
  • Ans. The earliest members of human race are traced back to Africa. A couple of hundred thousand years ago, some of our ancestors left Africa in search of food and habitat, while others stayed back. After a few years, the migrants slowly spread across the world.

    They went forward and backwards with groups sometimes separating from each other, sometimes coming back to mix with each other during moving in and out of Africa thus causing the spread of our race in all parts of the world.

The last lesson. Pg.  No.5 para 3

What does it mean when  M. Hamel says 

"Ah! That's the great problem with Alsace; she puts off learning till tomorrow".

Posted by Supriya Kumari (Feb 28, 2017 1:23 p.m.) (Question ID: 2781)

  • Answers:
  • Ans. M. Hamel observes that the great trouble with Alsace was that it put off learning until tomorrow. It means that the people of that town did not perform their work when it was required to be done and kept it off until later. The people of Alsace would not reprimand little Franz for not speaking or writing in one's own language yet calling himself a Frenchman. It was due to the fact that they had a great deal to reproach themselves with. The parents were not anxious enough for their children to learn and instead preferred to put them to work on a farm or at mills so that they could have more money.
