Large biological molecules are synthesized by removing a) covalent bonds. b) water. c) carbon. d) oxygen. e) peptides.

The correct answer is: B) water

Large molecules or macromolecules are necessary for the functioning of an organism and can be classified into four main types: proteins, lipids, nucleic acids and sugars (carbohydrates). All of them are polymers, meaning that are composed of many basic units (monomers) linked by different types of bonds into a functional structure.

Synthesis of these molecules is done through the dehydration (or condensation) reactions, which means that hydrogen (H) from one monomer combines with the hydroxyl group (OH) from another monomer releasing a molecule of water (H2O). Monomers linked via dehydration synthesis reactions share electrons and form covalent bonds.

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.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
