Answer:
A<u> covalent bond</u> will hold them together.
Explanation:
The two bromine atoms will share electrons to build a stronger bond and have a full valence outer shell (which makes them stable).
Hope this helps!

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly colored gas.
Answer:
B: +3
Explanation:
If Gallium loses 3 electrons, it will become an ion.
The ion will be positively charged because in this new ion, the number of electrons is lesser than the number of protons. The charge difference will impart a positive net charge on the ion.
- In a neutral atom, the number of electrons and protons are the same.
- For positively charged ions, the number of protons is greater than the electrons
If Gallium the loss of 3 electrons offsets the charge balance in the chemical specie. Thus, the ion will have a net +3 charge.
I believe your answer is the second option.
Answer:
The correct answer is A defective gene is replaced with a normal gene.
Explanation:
Gene therapy is an alternative therapy for the treatment of some diseases.
Although this therapy is still in development, and carries many risks, it is expected to have very good results in the coming years.
In such therapy the following happens:
- a defective gene is replaced with a normal gene.
- the introduced gene matches the defective one or produces a beneficial protein.
- faulty genes are disabled.
Given this information we can say that the correct answer is A defective gene is replaced with a normal gene
