Answer:
The correct answer is would be - geographic isolation.
Explanation:
The geographic isolation is also known as the speciation in which biological species experience genetic changes and on the basis of the genetic changes that experienced this separated with other organisms of the species.
It is physical separation or speciation of the biological organisms on the basis of geographical barriers of two population of the same species that keep them from interbreeding and reproducing.
Thus, the correct answer is - geographical barriers.
The outer planets are mostly formed of lighter elements because these three condense are a<u> lower temperature</u>.
<u>Explanation:</u>
The planets based on the location of the sun is divided into two, that is outer planets and inner planets.
The Outer planet which is far from the sun consists of larger quantity of lighter substances such helium, hydrogen, methane which would condense at the lower temperature. And remains gaseous inside the frost line that would exit far away for the sun so the temperature is low and the lighter materials are easier to condense in lower temperature to form terrestrial rocks.
Yeah where’s the picture?
I would say a hope it’s right
