Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
So I would say seaweed belongs in the hydrosphere.
I hope it helps.
Answer:
Explanation:
given cells at incubation = 2 million (2 x 10^6) Staph
cells at the start of incubation = 200 Staph
Total time =6hrs = 360minutes
Recalling that Number of generations = Log(cells at incubation) - Log (cells at the start of incubation)/0.301
- Number of generations = Log 2000000 - log 200 /0.301
= 20.93 generations.
- hence generation time = total time/number of generations
= 360/20.93 = 17.20minutes
as said, that the apple pie is left after 2hrs, it implies 8hrs (480minutes) will be the new total time; number of generations = total time / generation time
= 480/17.20minutes = 27.90 generations
- hence total number of bacteria after 8hrs = 2^n generations x initial number of bacteria
= 2^27.90 x 200 staph = 5.009 x 10^10 bacteria
