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.
'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum.
Hope this helps.

I believe the answer is B
Explanation:
Answer: Temperature on monday morning is 319,5K
Explanation: This is an example of Gay Lussac law on gases which states that at constant volume, pressure and temperature are directly related, so if one raises the other one does as well.
The equation that follow the law is :
P1 / T1 = P2/T2 where 1 is the initial pressure and temperature and 2 is the final state.
In this equation, values have to be expressed in atm for pressure and Kelvin for temperature.


The missing value is T2 (monday temperature), so we have to clear it from the equation
T2 =P2.T1/P1
Replacing values:
T2 = 1,073 atm . 338K /1,135 atm
T2 = 319,5 K
Answer:
The study island answer is "Remediating the mines keeps the contaminants from entering a watershed."
Explanation:
Many contaminants, particularly heavy metals, pollute the area around abandoned mines. If these contaminants enter the watershed, they can kill many organisms that live in that environment.
