Answer:
Living organism should obtain the 4 main types of macromolecules for maintaining proper body physiology.
Explanation:
The four major types of macromolecules that we should intake are Carbohydrate,protein,fat and nucleic. Each of them performs their specific functions.The 4 macromolecules are deeply interlinked to each other.
Deficiency of one of these four macromolecules can leads to various health hazards or health abnormalities.
For example if we do not intake carbohydrate then the lack of carbohydrate will weakens the body.The brain will not get sufficient amount of glucose to exhibit its biological function.
The protein deficiency leads to the development of marusmus a phusiological disorder occur due to protein energy malnutrition.
Answer:
Prokaryotes lack a true nucleus with well defined nuclear membrane and other membrane-bound organelles. Mitochondria are the double membrane bound organelle and hence is absent in prokaryotes. Mesosome is an extension of the cell membrane presence in the cytoplasm as infolding and serves to increases surface area and as a site for cellular respiration in prokaryotes. Histones are positively charged proteins that serve in the packaging of negatively charged eukaryotic DNA but are absent in prokaryotes.
So, the correct answer is option A.(DNA is complexed with histones).
