When linnaeus began classifying organisms in the 1700s, he categorized them as plant, animal, or mineral. these kingdoms were later revised to exclude minerals and expanded to include animals, plants, fungi, protists, and bacteria. which of the following best explains a reason for this change?

It seems that you have forgotten the given choices for this question. But anyway, here is the answer. When Linnaeus began classifying organisms in the 1700s, he categorized them as plant, animal, or mineral. These kingdoms were later revised to exclude minerals and expanded to include animals, plants, fungi, protists, and bacteria. The statement that best explains a reason for this change is technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms. 

Possible answers are : 
As new organisms were discovered, new kingdoms were created to sort them based on ability to interbreed.

 It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.

 Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms.

 Genetic research led to the discovery that each of these five kingdoms has a unique evolutionary ancestor.

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
