1. How much of downtown boston was original land? Where did the rest come from?

Hatshy [7]

History of Boston is described below.

Explanation:

When workers cut down Copp's hill the only thing they left untouched was the old three-acre burying ground. The city built a retaining wall around the graveyard to prevent it from eroding. In 1814, the Boston and Roxbury Mill Corporation built the Boston & Roxbury Mill Dam across the back bay
Originally called Tremontaine for the three hills in the area, the Puritans later changed the settlement's name to Boston, after the town in Lincolnshire, England, from which many Puritans originated.
South Boston, which was front and center in the battle, is no longer that close-knit old school “tough-as-nail” Irish Catholic enclave. “Southie,” as it is still fondly referred to, houses the world today flaunting some of the best restaurants and expensive housing in the city
Boston was founded in 1630 by English Puritans fleeing religious persecution. On 29 March 1630 a fleet of 11 ships carrying 700 people sailed from England to Massachusetts. They were led by John Winthrop (1588-1649). At first the people settled at Charlestown, which had been founded the year before.
Much of Boston's coastline is man-made land. The original shoreline, from 1630, is visible in dark green on this map. Land made between 1630 and 1995 is light green.Boston is a safe city, but as with any major city, you should take the usual safety precautions. Stay in well-populated areas, travel with others, especially at night, and keep track of your belongings. The tourist areas in Boston are generally safe, but some areas deserve mention.

ss7ja [257]

Explanation:

options:

contain different chemical elements
form different proteins
carry different nucleotides
perform different functions

Because they have different structures, they most likely-perform different functions.

The corresponding image is attached below...

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers. Their structure is closely related to their function.

Basic makeup: C, H, O -with many polar OH groups

Further Explanation:

Many long chain polysaccharides are made up of glucose joined by regular α, 1-4 glycosidic bonds used as energy storage (produced through phtosynthesis) and used for ATP synthesis via respiration, ethyl alcohol fermentation and lactic acid fermentation. Branched chains of α, 1-4 glycosidic bonds linked by α(1→6) glycosidic bonds make up glycogen, a storage molecule in animals. Plants are mostly comprised of structural units cellulose and lignin. However, cellulose is their main structural polysaccharide, found within cell walls.

It is made up of special β, 1-4 glycosidic bonds, which give structural polysaccharides their rigid, strong structure; cellulose is not water-soluble and is highly stable. However, if these alternating bonds aren't present, the plants would lose their main structural support, which allows larger plants, and trees to grow upwards towards sunlight despite their mass. When arranged in α 1-4 glycosidic bonds these molecules are water-soluble; water would be able to flow readily out of the plant tissue. Thus the plant cells and tissue, would not retain their shapes and may be limited in their potential height without structural support.
