Which causes uncontrolled growth of plant tissue, resulting in a tumor? a. rhizobiumb. agrobacteriumc. bacillus anthracisd. yersinia pestis

Agrobacterium

Explanation:

Agrobacterium tumafaciens is the causal agent of tumors in flowering plants.

It is a soil bacterium which enters the plant through wounds in roots or stems. When this happens, the bacterium inserts a segment of DNA called “T-DNA,” from a plasmid, into the plant cell. This is incorporated at a semi-random location into the plant genome. Then this stimulates the plant tissues to grow in a disorganised way, producing swollen galls.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
