Well if there are 16% percent adenine, there has to be a complementary 16% thymine.
This makes up 32% of the bacterial DNA out of the 100%. So to find out the percentages for guanine and cytosine, let's subtract 32 from 100.
100-32 = 68% guanine and cytosine.
Since these two are complementary as well, divide 68 by 2 to find the percentages for both guanine and cytosine.
68/2 = 34%
So, in total, there are 16% adenine, 16% thymine, 34% guanine, and 34% cytosine.
Answer:
In uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate. Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old.
And that's how after rounding we know that earth is 4.5 years old.
Answer is D. The phosphate group of membrane lipids are negatively charged.
The cell or plasma membrane is a bilayer of phospholipids. The two phospholipids layers are opposite to each other. Each phospholipid molecule consists of a phosphate group and a lipid. The phosphate form inner and outer layers of hydorphilic and are negatively charged 'heads' and lipid forms the tail, hydrophobic and non-polar. Since phosphate is negatively charged it repels negatively charged molecules and do allow them to pass through it.
