The number of chromosomes. For example, humans have 46.
the particle size of the sediments within the rock
The primary characteristic used for the first division of organisms is whether they are prokaryotic or eukaryotic. Prokaryotic organisms lack a true nucleus and membrane-bound organelles, whereas eukaryotic organisms have a distinct nucleus and membrane-bound organelles within their cells.
No, the biological species concept can be applied to both extant and extinct organisms. It is a useful framework for defining species based on reproductive isolation and gene flow within populations, regardless of whether those populations currently exist or not.
Two organisms can reproduce if they are of the same species and have compatible reproductive systems. Factors such as genetic compatibility, timing of mating, and physical proximity also play a role in determining whether reproduction can occur between two organisms.
The characteristic used to place organisms into kingdoms is their cell type. Organisms are classified based on whether they are prokaryotic (lacking a nucleus) or eukaryotic (having a nucleus). This fundamental difference helps separate organisms into broad categories at a higher taxonomic level.
The most important characteristic is the polarity of the solvent and solute.
A species is a group of closely related organisms. Organisms belong to the same species if they can mate and produce fertile offspring. A lion and tiger are not the same species because they can make a liger, but it will not be fertile.

because it determines whether a species will evolve to keep up with its predator or prey

Two species are typically placed in the same genus based on shared physical characteristics, genetic similarities, and common evolutionary ancestry. Taxonomists consider a combination of these factors when determining the classification of species into different genera.
Whether your foot is on it or not.

True. A species is defined as a group of organisms that can interbreed with one another and produce fertile offspring. This ability to produce viable offspring is a key aspect in determining whether organisms belong to the same species.
The salinity level is the primary characteristic that distinguishes marine ecosystems from freshwater ecosystems. Marine ecosystems have high salinity, while freshwater ecosystems have low salinity. Additionally, the types of organisms and adaptations to salinity levels further differentiate these two types of ecosystems.
