Which formula represents a polysaccharide that consists of five monosaccharides joined together by dehydration synthesis? a. c6h12o6 b. c30h60o30 c. 5c6h12o6 d. c30h52o26

The correct answer is option D, that is, C30H52O26.  

The majority of macromolecules are formed as single building blocks or subunits, known as monomers. The monomers attach to each other through covalent bonds to produce bigger molecules called polymers. In performing so, the monomers discharge molecules of water as byproducts. This kind of reaction is called dehydration synthesis.  

In a dehydration synthesis reaction among the two un-ionized monomers, like monosaccharide sugars, the hydrogen of one monomer merges with the hydroxyl group of another monomer, discharging a water molecule in the process.  

The withdrawal of a hydrogen from one monomer and the withdrawal of a hydroxyl from the other monomer permits the monomers to share electrons and produce a covalent bond. Therefore, the monomers, which are combined together are being dehydrated to permit for the production of a larger molecule.  

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
