Explanation:

To refine the meaning of a scientific - related term like "tissue" in an article, physical descriptions and technical language are most likely used. Metaphorical and figurative language are more for literary or non - technical contexts. Breaking down language behind meaning might be more about etymology. Creating a friendly tone doesn't refine the meaning. Technical terms in science are best defined with physical descriptions and technical language.

Answer:

through physical descriptions and technical language
