The secretory systems of Type III and Type IV pathogenic bacteria differ in their mode of attacking cells in which of the following ways?
A. Type III systems bind to the cellular membrane by slimy mucilage and toxins diffuse across the membrane, whereas Type IV systems infect materials using pili as transfer tubes. B. Type IV systems bind to the cellular membrane by slimy mucilage and toxins diffuse across the membrane, whereas Type III systems infect materials using pili as transfer tubes. C. Both systems attach to cells in the same way but they differ merely in the chemicals that they inject into the host cell. D. Type III systems use flagella modified as "syringes" to inject materials into cells they are infecting whereas Type IV systems use modified pili as transfer tubes. E. Type IV systems use flagella modified as "syringes" to inject materials into cells they are infecting whereas Type III systems use modified pili as transfer tubes.
Intestinal bacteria are necessary for plant-eating animals to digest
A) cellulose. B) lipids. C) proteins. D) carbon dioxide. E) nitrogen.
A group of geneticists exposed the seeds of a dicot plant to various levels of radiation in order to induce random mutations. Many of the irradiated seeds failed to germinate
Some of the seeds, however, germinated in the lab and were carefully studied. The scientists discovered a mutation that prevents the formation of a hypocotyl hook during germination. Based on this scenario, the mutant plant most likely germinated A) but was unable to photosynthesize. B) but damage to the cotyledons prevented the seedlings' emergence from the soil. C) but the mutated hypocotyl hook caused damage to the emerging root tip. D) and grew like a normal plant. E) but the mutated hypocotyl hook failed to push the cotyledons above the soil.
