The answer is <span>Disaccharides are different in structure because they are not made up of the same monosaccharides, and this gives them different properties.
Both sucrose and lactose are disaccharides, however, they are made up different monosaccharides:
Disaccharide = monosaccharide + monosaccharide
Sucrose = glucose + fructose
Lactose = glucose + </span>galactose
Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.
Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security and lower risk of fuel spills while reducing the need for imported fuels. Renewable energy also helps conserve the nation's natural resources.
Grass often dies near roads that have been <span>salted to remove ice during the winter because the salt spread out into layer of the grass </span>cell. Then the water goes into the ice because the grass is attracted to the salty ice water. Hence, this dehydrates the plant cell by removing excess water, so it dies since it can no longer perform the proper cell function.<span> </span>
Answer:
Radioactive dating uses radioactive elements to date matter such as rocks and fossils. As the radioactive elements disintegrate, they turn into other elements. Scientist then use the ratio of the two elements to determine how old something is.
Explanation:
I am more of a chemistry person, but my best answer is the double-helix structure. The DNA rotate around a central point allowing it to keep a constant distance
