Many biomolecules are also polymers. poly - many. mer - parts. a polymer is a molecule made up of many parts. the image above is a monomer or part of a single part of a common polymer. what is the monomer and polymer?

The monomers:

In chemistry, a monomer is a most often organic substance used in the synthesis of oligomers and polymers during an oligomerization or polymerization reaction1. The word monomer comes from the Greek monos, one or only one, and meros, part.

In biology, a monomer (or subunit) is the building block of multimeric proteins such as hemoglobin. The arrangement of the monomers with respect to one another is described by the quaternary structure of the protein.

Polymers:

Polymers are a class of materials. From a chemical point of view, a polymer is a macromolecule (molecule consisting of the repetition of many subunits (or many monomers)).

Polymers can be made naturally (by living organisms) or artificially (by humans).

b

is correct hope this   also i learnd this in middle school

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
