Plant pollen can provide information of what type of plants grew during that era and area. In turn, it can also determine how the Earth''s climate has changed over time. Identifying the species of the plants through the pollen will help because when scientists compare them to the plants today and the climates they thrive in, they will be able to tell what type of climate that certain plant existed in.
The answer is True.

It would be water.
Because inside the cell it contains water. Which means the volume of the cell is influenced by the certain amount of water that's in the cell.<span />
The appropriate answer is d. a topographic maps. A topographic map shows the physical features of the earth's surface. A topographic map would therefore highlight features such as mountains, valleys, rivers and other landforms.
The height above sea level of these landforms are represented on the map by contour lines. These are lines on a map that show the height of the land. Colour is sometimes used to represent height if contours are not used.
Answer:
This question lacks options, options are: a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.
Explanation:
Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.
