‘Noble gases’ are least reactive as their outer shells are fully filled with electrons. These do need to share their electrons from outer shells with other elements .

Explanation - An organism has encountered reproduction, getting energy and staying healthy as their challenge. Limiting factor plays an important role in this. When the amount of limiting factor is sufficient then different organisms try to grow and reproduce but here the competition between the species arise.
Different species need to compete with each other for their food, growth and reproduction. The species that is unable to sustain itself in the amount of limiting factor available tends to get extinct.
Bees impact the environment because they support the growth of flowers and plants and the produce honey.
Because they each get half their dna from both parents. in pea plants for example the offspring have a total of 14 chromosomes thus inheriting 7 from each parent. plus genetic mutation is always a possibility making the offspring genetically different from the parents.<span />
