Understanding the experimental design what hypothesis were the researchers testing in this study? what hypothesis were the researchers testing in this study? the disease-suppressive properties of soils are due to the activities of soil microorganisms. sugar beet seedlings have a higher rate of fungal infection in heated soils. sugar beet seedlings have a lower rate of fungal infection in disease-suppressive soils. soils can be treated to reduce their ability to suppress fungal disease in seedlings.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
