The correct option is C.
Living organisms that live in the littoral zones in the ocean are used to frequent changes in temperature and in the salinity of the ocean water. For an organism to survive in this environment, it needs to have adaptive features that will increase its survival. The littoral zone is divided into three zones, which are high, middle and lower littoral zones. Organisms living in high littoral zone have adaptive features that make them more adapted to desiccation due to the long hours of sunlight to which they are exposed. The organisms are usually exposed directly to the air or they can be enclosed in burrows.

The topsoil is the upper and outermost layer of soil, usually the top 2 inches to 8 inches. It contains the highest concentration of organic matter and microorganisms. Topsoil is used as the medium for all plant growth, whether it is a lawn, garden or prairie.
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
