Hey here is the answer,
It is a globular protein, it contains one iron atom, that can bind one oxygen molecule. Therefore it has high affinity for oxygen.
Hope this helps you...
all the thymine pairs with adenine, therefore there is the same number of adenine and thymine bases and the same percentage
so we have 28%thymine and 28% adenine
100-28-28=44% left
this 44% is guanine and cytosine. All of the guanine pairs with cytosine and all of the cytosine pairs with guanine so we have 44/2=22% cytosine and guanine
composition:
28%adenine
28%thymine
22%guanine
22%cytosine
I do believe that it is both naturally occurring and caused by human activity. Although science has proven that it is something that naturally progresses with time, humans have sped up the process. Hope this helps:)
Aero is the prefix for oxygen or air
Aerobic= needs air
Anaerobic=no air needed
