Three Worlds, Three Views: Culture and Environmental Change in the Colonial SouthTimothy Silver

For nearly three hundred years before the American Revolution, the colonial South was a kaleidoscope of different people and cultures. Yet all residents of the region shared two important traits. First, they lived and worked in a natural environment unlike any other in the American colonies. Second, like humans everywhere, their presence on the landscape had profound implications for the natural world. Exploring the ecological transformation of the colonial South offers an opportunity to examine the ways in which three distinct cultures—Native American, European, and African—influenced and shaped the environment in a fascinating part of North America.
The Native American WorldLike natives elsewhere in North America, those in the South practiced shifting seasonal subsistence, altering their diets and food gathering techniques to conform to the changing seasons. In spring, a season which brought massive runs of shad, alewives, herring, and mullet from the ocean into the rivers, Indians in Florida and elsewhere along the Atlantic coastal plain relied on fish taken with nets, spears, or hooks and lines. In autumn and winter—especially in the piedmont and uplands—the natives turned more to deer, bear, and other game animals for sustenance. Because they required game animals in quantity, Indians often set light ground fires to create brushy edge habitats and open areas in southern forests that attracted deer and other animals to well-defined hunting grounds. The natives also used fire to drive deer and other game into areas where the animals might be easily dispatched.</span>
Are you asking for DNA or chromosomes or something? You asked for which of the following but then dont give the following
The seeds an evolutionary advantage for seed plants because seeds develop into adults without sxual reproduction.
<h3>What is the evolutionary importance of the seed?</h3>
Seeds play an important role in the dispersion of plant species, that is, they ensure that plants spread throughout the environment. In addition to guaranteeing a greater area of domain for the species, competition between the newly born plant and the mother plant is also avoided.
Seeds allow the expansion of a type of plant around the world in addition to being a form of asexual reproduction that makes it unnecessary to join gametes.

If a star is located 100 light years from earth the light will tack 100 years to reach earth I hope I helped you and good luck
Answer:
Hershey Chase and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.
Explanation:
Both experiments have was based on different phenomenon and techniques to prove same conclusion.
Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.
Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.
