Answer:
The answer is 17190 years
Explanation:
Original amount was 5730. To become 1/8 of the original amount, three (3) half life periods will demand because after first half life the amount will become 1/2 and after second half life, amount become 1/2 again (1/2 x 1/2 = 1/4). Third half life, the amount become half 1/2 again (1/2 x 1/2 x 1/2 = 1/8).
For the 3 half life periods we have original amount x numbers of half life periods = 5730 years x 3 = 17190 years
The answer is.
Its cells are widely dispersed and surrounded by a fluid
Answer:
A) The two strands of a DNA molecule are parallel and complementary.
Explanation:
DNA is a polymer of nucleotide and this nucleotide are made up of a deoxyribose sugar molecule, a nitrogenous base, and a phosphate group. In DNA genetic information of the cell is stored in the form of nitrogenous bases.
DNA is double-stranded and both the strands run anti-parallel with each other. This anti-parallel orientation provides the nitrogenous base of one strand to form hydrogen bonds with the nitrogenous base present on the opposite strand.
In DNA adenine base pairs with thymine with two hydrogen bonds and guanine base pairs with cytosine with three hydrogen bonds. So the false statement is A.
ya the correct answer is B.
