Answer:
(C) The main predator of these fish is another species of fish on which alligators also prey.
Explanation:
The ecosystems are complex systems, and removing one species of them, always has a chain reaction and affects the population of the other species, be it in a positive or negative manner. In this case, the alligators prey upon fish, multiple different species. The alligators though have been removed from the ecosystem, thus the apex predator exists no more. This has opened up the top predator niche in the food chain in this particular ecosystem. The predatory fish species had no predators of its own, so its population increased, thus it needed more food, and that food was obtained by hunting the other fish species, resulting in a decline in the population of the other species of fish. Only when the carrying capacity is reached in the ecosystem for the predatory fish, the population of the other fish will stop declining.
False. Hypothermia is caused by the body being exposed to cold weather or immersion to cold water. I hope this answer is what you were looking for.
The species is on CITES Appendix II, but its status is poorly known. The IUCN Red-List (2007, www.iucnredlist.org) classified it as Lower Risk/Least Concern
Answer:
Eukaryotic and Prokaryotic cells are fundamentally different.
Explanation:
A prokaryotic cell is basically an entire organism that works within a single cell. Its genetic material is not in a nucleus.
A eukaryotic cell is part of an organism. This cell has its genetic material in the nucleus. In addition, it possesses organelles.
All cells are not the same because some, like the prokaryotic ones, make up an entire living organism. Others, like the eukaryotic cells, are part of much more complex living forms. Furthermore, each cell type within each category has unique functions.
An efficiency apartment can be compared to a prokariote. Prokariotes have everything they need in one cell. A mansion is more similar to a eukaryote. Every room of the mansion is important for the fully equipped mansion.
