Presidential Reconstruction
In the spring of 1865, the Civil War came to an end, leaving over 620,000 dead and a devastating path of destruction throughout the south. The North now faced the task of reconstructing the ravaged and indignant Confederate states. There were many important questions that needed to be answered as the nation faced the challenges of peace:
<span>Who would direct the process of Reconstruction? The South itself, Congress, or the President?Should the Confederate leaders be tried for treason?How would the south, both physically and economically devastated, be rebuilt? And at whose expense?How would the south be readmitted and reintegrated into the Union?<span>What should be done with over four million freed slaves? Were they to be given land, social equality, education, and voting rights?</span></span>
They survive without water by entering a special mode, otherwise called as shriveling. They can lose even 95% of water in their body and still live, even though they would look like dead plants, they would actually be alive. In the absence of water, tardigrades use a sugar called trehalose, which becomes their source of life until they find some water.
Antibodies, also called immunoglobulins, are proteins manufactured by the body that help fight against foreign substances called antigens. When an antigen enters the body, it stimulates the immune system to produce antibodies. (The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it.<span>

Answer:
The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>
Explanation:
Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.
