Question

1. what characteristics does the linnaean system use to name organisms?

environmental
evoluti
genetic
physical

Explanation:

The Linnaean system, developed by Carl Linnaeus, is a method of classifying and naming organisms. It primarily uses physical (morphological) characteristics. Organisms are grouped based on their visible physical traits such as shape, structure, etc. For example, plants are classified based on leaf shape, flower structure, while animals might be classified based on body parts, skeletal structure. Environmental characteristics relate to where an organism lives, evolutionary is about ancestry (which was not the main focus of Linnaeus as evolutionary theory came later, though Linnaeus' work laid some groundwork), and genetic (molecular - level) characteristics were not detectable in Linnaeus' time (genetics as a field developed much later).

Answer:

physical
