Increasing the tube potential: a. Improves film contrast b. Increase

1.	Increasing the tube potential: a. Improves film contrast b. Increases the dose to the patient c. Reduces the exposure time d. Increases geometric unsharpness e. Has no effect on motion unsharpness
Answer» a. False. It decreases film contrast by reducing the probability of photoelectric absorption in tissues and increasing the scattered radiation contributing to the final image. b. False. The beam is more penetrating; therefore, less radiation is required to produce an adequate image. c. True. d. False. It has no effect. e. False. Using a higher kV reduces the required exposure time so it can indirectly reduce motion unsharpness.

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
