i think this is a biology question but regardless a threatened species is same as endangered which is going to become extinct in the near future but i say the best answer is threatened with becoming extinct in the near future.
Answer:
Here's what I get.
Explanation:
The MO diagrams of KrBr, XeCl, and XeBr are shown below.
They are similar, except for the numbering of the valence shell orbitals.
Also, I have drawn the s and p orbitals at the same energy levels for both atoms in the compounds. That is obviously not the case.
However, the MO diagrams are approximately correct.
The ground state electron configuration of KrF is

KrF⁺ will have one less electron than KrF.
You remove the antibonding electron from the highest energy orbital, so the bond order increases.
The KrF bond will be stronger.
Answer:
The nucleus contains all of the genetic material for a eukaryotic cell, but this genetic material needs to be protected.
