The International Date Line (IDL) is a line that separates the world into two hemispheres. It was first established in 1884 during the International Meridian Conference which was attended by 26 countries. It is located at the 180° longitude, which is the east of Greenwich, United Kingdom. 

The International Date Line does not follow a straight line because it has to avoid countries or groups of islands. The main purpose of the zigzag pattern of the IDL is to avoid confusion regarding time.

The IDL is important because it's the basis for our time zones. Back in the nineteenth century, scientists as well other professionals in various industries proposed to adopt the 24 time zone system which centered on the IDL's principle of adopting the proper "time". The IDL divides the world into two dates: the East of the IDL is a day behind compared to the West of the IDL.

An adaptive trait: (mark all that apply)
snow_tiger [21]

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.
