Answer:
[a] varies in its characteristics according to local environmental circumstances
[b] becomes common within a species through natural selection
[d] tends to promote the well being of an organism in its natural or social environment
Explanation:
The adaptive traits in the living organisms have a simple basic role, that is to make the organism better suited for survival in its environment. The adaptive traits come in all sorts of different shapes, be it some that are manifested in the physical appearance or in the behavior of the organisms. Adaptive traits can be increased speed, prolonged neck, living in a groups, developing thorns and many more. This type of traits occur when the organisms face increased competition or when the environment in which they live starts to change, so in order for them to survive, they start to develop traits that will make them better suited for the new conditions and more competitive. The main principle through which the adaptive traits are transferred and rapidly increase in a population is through natural selection, as the organisms choose the ones that have advantageous traits for their mates, while they live aside the others.

Explanation:
D, the universe began 13.8 billion years ago (I assume this test may be a little outdated since the updated version is 13.8 billion years ago, but D is the closest to the answer, so I would go with D).

Answer:
between 200 and 269 feet (60 and 82 metres) in height.
Explanation:
Perimeter = 3x. Area = x^2 * sqrt(3)/4. Explanation of area:. You can divide an equilateral triangle into 2 right triangles, each with a common side we will call y.. Area = area of first right triangle + area of second right triangle = (x/2)*y/2 + (x/2)*y/2 = xy/2. Now: y^2 + (x/2)^2 = x^2 so y…
