<h2>Answer:</h2>
Salivary amylase breaks the chemical bonds of starch to form sugar monomers.
<h3>Explanation:</h3>
- Amylase is one of the digestive enzymes which catalyze the breakdown of starch molecules into its monomers.
- A starch molecule is made of the Glucose molecules which are bonded with each other with glycosidic linkages.
- Salivary glands secrete saliva into the mouth cavity.
- Saliva contains amylase for the digestion of starch are known as salivary amylase.
- Steps in the digestion of sugars start from the action of this enzyme.
Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.

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>
