I believe that elevated serum creatinine levels indicate a kidney disease
Answer:
3'-TTACGATG-5'
Explanation:
The DNA sequence is in couples where A is united T and G is united C, so what we do is replace in the complementary sequence the original nucleic acids, remember A-T, G-C.
5'-AATGCTAC-3'
3'-TTACGATG-5'
To remember: the DNA sequence is 5'-3' in one sequence and its complementary is inverse, what means it goes 3'-5'.
Also the T-A is united by 2 hydrogen bonds, and G-C is united by 3 hydrogen bonds.
The answer should be skin
Answer:
Explanation:
In terms of old school electron shells - One Hydrogen atom on it's own has an empty shell, and therefore to fill the shell it needs another electron. In the case of Helium, it already has two electrons at the same energy level - so it cannot accept any new electrons i.e. it cannot form new bonds.
Answer:
There are several hypotheses as to why Earth's climate changed: an ice age and a meteor collision are two. Regardless of why the climate changed, dinosaurs could not adapt to a new environment to avoid extinction. Mammals did not become a dominant species on Earth until the extinction of dinosaurs.
