Fluorine is a nonmetallic, diatomic gas with the symbol F and atomic number 9. Atomic number represents the number of protons in the atom. When F is neutral it means that the number of protons is equal to number of electrons. But, when F is an ion (F-), the it has more electrons (10) than protons, meaning its an anion.
The last one is right answer i think
Answer:
thanks for the points May God bless you always
The answer is Retroviruses integrate DNA randomly in the
genome. While retroviruses integrate their
DNA permanently in their host genome, hence
a good tool for gene therapy, its risk of inserting
DNA at an unintended
location on target genome can cause insertional
mutagenesis. This mutation can cause activation of oncogenes hence lead to tumor
growth.
