What conclusion can you draw from the data? a. all rhizobium strains have a similar, highly positive effect on plant growth. b. some rhizobium strains are much more effective at promoting plant growth than other strains; the most ineffective strains have little positive effect. c. some rhizobium strains are much more effective at promoting plant growth than other strains; however, even the most ineffective strains have a significant positive effect. d. none of the rhizobium strains used in the study have a substantial positive effect in promoting plant growth.

Rhizobium is a bacterium that has positive effects on plant growth. Different strains display a wide range of effectiveness, from a little positive effect to a massive one. The strains used in the study did not show a positive effect promoting plant growth, so we could say that they ARE NOT Rhizobium strains and need to be properly identified.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
