The number of bacteria in a culture is increasing according to the law of exponential growth. The initial population is 250 bacteria, and the population after 9 hours is double the population after 1 hour. How many bacteria will there be after 3 hours? (Round your answer to the nearest whole number.)

250

Explanation:

According to the question the number of bacteria population becomes double in 9 hours to that of 1 hr that means bacteria is dividing in 9 hours. Each time the bacteria divides, the numbers become double.

As we have found that bacteria is dividing in 9 hours so for the first 9 hours the number will be same as initial population i.e. 250. But just after nine hours the population will be double i.e. 500.

So, after 3 hours the population will be same as initial population, 250.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

not too sure but maybe in the hot springs.
