The answer to that would be B. This is because carrying capacity is the amount of something that can be handled.
The pH scale measures the concentration of how acidic or basic something is. The lower the number below 7, is acidic. Above 7 is basic. 7 is waters purest form.
Rain forests are huge carbon sinks, as plants and trees actively remove carbon dioxide from the atmosphere and store the carbon in biomass. This is a vital ecosystem service for counteracting climate change. Forests regulate the climate, as evapotranspiration from forests influence precipitation patterns and the temperature. Many as yet underdiscovered plants may be of benefit to us as sources of useful products or drugs. Rain forests act as a refuge for vulnerable plant species, thereby protecting them from human over-exploitation and saving biodiversity for future human generations.
Answer & Explanation:
All archeas are single-celled organisms, and despite having prokaryotic cells, there are both similarities and differences between archaea and bacterial cells and also with eukaryotes.
Archaea have only one cell that has no nucleus or real organelles, and its cells have membranes composed of branched lipids, which greatly alter the structure of the archaeal cell membranes. In addition, the archaea have only one DNA strand (uniqueness).
Animal cells differ from archeas because they are multicellular (organisms with several cells), each one having a nucleus, and they also have specialized organelles.
In addition, animal cells have compounds called phospholipids in their membranes, which are unbranched lipids, and therefore do not cause major changes in the structures of their cells. Finally, animal cells have double-stranded DNA (complementary duplication).
