Sladkaya [172]

Answer:

"This is a specific example of a reproductive barrier, called behavioral isolation or sexual isolation".

Explanation:

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, and the postzygotic mechanism avoids the zygote to develop and reach the adult stage.

There are different types of reproductive barriers, one of them is behavioral isolation, also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that many species occupy the same area but they are not sexually attracted to each other and might even be rejected because of behavioral factors, and this is why they do not get to mate. This mechanism includes courtship patterns or mating rituals, and specific chemical signals that allow the recognition between individuals of the same species. A typical example is the recognition songs of some species like frogs, birds, insects, and etcetera.

If an atom has twelve electrons, how many electrons are in the n=1 energy level? how many electrons are in the n=2 energy level?

Serjik [45]

Magnesium has 12 electrons.........which wud mean that in the 1st energy level(n=1) there r 2 electrons, in the 2nd energy level(n=2) there r 8 electrons and in the 3rd energy level(n=3) there r 2 electrons.......its simple......use the formula 2n^2 where n= 1,2,3,......

so the electron configuration of Magnesium in 2,8,2..................or more precisely 1s2, 2s2, 2p6, 3s2
