How is a ratio used to describe change a it represents a. relationship between two values numerically b. it represents a relationship between two values on a scale c. it represents a relationship between two values in a picture d. it represents the relationship between two values graphically

Ratio used to describe a change that represents relationship between two values numerically.

Therefore, the correct answer to the question is option A.

Explanation:

Ratio is a relation between two numbers. This relationship is represented numerically. The relationship is not represented graphically or by a picture manner. Also, it is not the relationship which is represented on a scale.

Hence ratio is relationship which is represented numerically. The ratio is defined as a part of something in the whole. By ratio we can also calculate the parts whichever is needed.  

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
