False
Proteins are polymers of molecules called amino acids, some contain thousands. Lipids are formed when a glycerol molecule combines with compounds called fatty acids, therefore they are not polymers because they contain one molecule and are not macromolecules. Hope this helps! :)

some cells are living and some cells are not

MRNA is needed in the cells because it directs the synthesis of proteins which is found in the cytoplasm. It is a molecule that carries the message contained within DNA to the ribosome. The Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide.
The ocean moderates the Earth's climate. Most solar radiation occurs at the Equator, whereas the poles receive little radiation. The ocean<span> transport warm water from the Equator toward the poles and cold water from the poles back to the Equator. The oceans provide a habitat for much of the marine life exploited by humans, such as harvested fish. The oceans act as a massive carbon sink, as phytoplankton absorb carbon from the atmosphere through photosynthesis. The ocean also provides a medium for large scale transportation of goods through shipping. It is unlikely that vehicles as large as container ships could ever be transported over land.</span>
