<span>The answer is true, professionalization of science is due to specializing the field of science. Science was a key factor that enhances our world today. It is by the help of the scientist and professionals who invented things that are thought by us. Scientists before are specializing science which helped them analyze their hypothesis until they will get into their conclusions. Specializing this became a profession to a lot of those scientist to pursue and invent more.</span>
DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.
All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).
Answer:
False
Explanation:
The glycocalyx is the layer surrounding the plasma membrane of the eukaryotic and prokaryotic cells.
The glycocalyx is composed of the carbohydrates and the protein molecules like the proteoglycans, glycosaminoglycans and the other glycoproteins.
The glycocalyx has been identified in the bacterial cells as a protective layer from the host bu in eukaryotes the glycocalyx helps in the cell to cell interaction and communication.
Since the glycocalyx is not composed primarily of the proteins but of the carbohydrates and the proteins therefore false is the correct answer.
