Which reaction would you employ to build a disaccharide from two monomers of glucose?

GenaCL600 [577]

Answer:

D. dehydration synthesis

Explanation:

Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).

Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.

Which one of the following is a major difference between the circulatory systems of earthworms and fish?

labwork [276]

a. Fish have a single central heart; earthworms have several hearts.


Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and metabolic waste taken away in a continuous, never ending process.
A mechanism is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this bill splendidly. It is a specialized organ system which allows blood and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs to be expelled from the body.
