Hello!
The genetic material of all organisms which is made up of two twisted strands in a double helix is called DNA (DeoxyriboNucleic Acid)
DNA is the basis of all genetic information. It contains all instructions for the development and functioning of all living organisms and some viruses. The main function of DNA is the long-term storage of information to build other cell components like Proteins and RNA. It is composed of two strands with 4 possible bases which are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
Have a nice day!
Answer:
Atmospheric nitrogen is not heavier than chemical nitrogen, largely because “chemical nitrogen” is ultimately derived from atmospheric nitrogen. On the other hand, you could be asking why the atomic mass of nitrogen is not the same as the mass of nitrogen gas; that's because gaseous nitrogen is diatomic, .
Explanation:
This is from Google.
Hope this helps :))
FeS is an example of an ionic compound as in the formula there is a metal of Fe iron chemically bonded to the nonmetal S sulphur. Resulting in a strong electrostatic attraction due to the transfer of valence electrons from the iron to the Sulphur.
I am sorry but do not listen to the link above it is a virus and it will be installed if you do stay safe and spread the word
