8%
Explanation:
In a DNA molecule the no. of Adenine bases equal to that of Thymine bases
The no. of Cytosine bases equal to that of Guamine bases.
If we take no. of Thymine bases as x and no. of Cytosine bases as y,
Adenine + Thymine + Cytosine + Guamine = 100
x + x + y+y = 100
2( x+y) = 100
x+y = 50
y=42
therefore x= 50-42 = 8%
Negatively charged particles in atom - Electrons
I think the answer is white sand (sorry if i am wrong)
Fluorine has 9 protons and 9 electrons
Iodine has 53 protons and 53 electrons
Ionic reaction when a metal and non metal are together a molecule is when a metal abs metal react hope this helps
