There is no element with one valence electron and six energy levels. Only two valence electrons and six energy levels.
Answer:
Calcium
Explanation:
A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.

Blowfly adults looking for a place to lay their eggs
Explanation:
Blowfly adults are attracted to the gases and fluids of a dead body and usually lay their eggs on a dead body within the first two days after death.
The eggs then turn into larvae then enter pupal stages and then become adults themselves. Forensic entomologists can determine how long a body has been dead by the stage of development of the blowfly with the ambient temperatures that have been present.
