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.

You did not included your list of selections.  Some general properties ascribed to DNA are storage and expression of information and variables through mutations.  Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell.  DNA nucleotides contain deoxyribose.  DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit.  In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.  

Hope this helps, I love Science.

Your family prepared an emergency plan in case of a natural disaster. Look at the list below and then select one additional item
tino4ka555 [31]

Answer: A safe place in the neighborhood seems the most reasonable or  D

Explanation:

A map of the house  wouldn't make sense because im pretty sure they would know around there house. An enlarges picture of each family member would also not make sense because it is just not helpful at all. A wallet card for each family wouldn't help them in there situation. A safe place for the family pet would help the pet but not everyone in the house so no. A list of friends for each family member would really be useful.
