Homeostasis is the maintenance of a relatively constant internal state. It is the process by which living organisms maintain a state of equilibrium in their internal environment. The organs that take part in homeostasis include: the skin, kidney and liver. These organs works together to maintain a stable internal environment.
Cytosine(C) binds with Guanine(C)
Adenine(A) binds with Thymine(T)
a.From here we can deduct that there are the same number of nucleotides of guanine that as cytosine=>G=45 base pairs
b.2A=100-G-C
2A=100-90 2A=10 A=5 base pairs
<span>Changes in a DNA sequence that affect genetic information are known as mutation.</span>
I believe the answer is option A
