A gram-negative, nonsporulating rod that is highly motile, oxidase negative, facultatively aerobic, ferments glucose, and urease-positive is likely to be of which genus?

Proteus

Explanation:

Proteus is a gram-negative bacteria belonging to the family Enterobacteriaceae. The Enterobacteriaceae family are gram negative rod, facultatively aerobic, nonsporulating and oxidase negative. They ferment glucose.

The oxidase test is used to differentiate between member of the family and Pseudomonas (Pseudomonas is oxidase positive).

Proteus is known for its ability to swarm a culture medium due to its high motility (called swarming motility). Proteus is also urease positive, it produces the enzyme urease, which catalyses the breakdown of urea.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
