Gamma rays because microwaves, visible light and radio waves wouldn’t come in handy if an astronomer would want to study the composition of planets and stars.
This
reserve is home to terrestrial and marine mammals, including grizzly
and polar bears, caribou, wolves, and wolverine as well as beluga and
bowhead whales, walrus, and several species of seals. It was
established for the purpose of preserving unique wildlife,
wilderness, and recreational values.
The
most complex level of organizational hierarchy in the Arctic National
Wildlife Refuge that is preserved is every ecosystem in the area.

Answer:
A= 20%
G= 30%
T= 20%
C= 30%
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if Adenine makes up 20% of the DNA nucleotides, Thymine is also 20%.
Then, 20% + 20% + C + G = 100%
40% + C + G = 100%
C + G = 100% - 40% = 60%
So, divide 60% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 30%
Finally, A= 20%; G= 30%; T= 20%; C= 30%
