The protein gp120, involved in binding to the cell surface of host cells, is a glycoprotein. This means that is linked to what non-proteinaceous molecule an oligosaccharide
Definition and Classification of Oligosaccharides :
Oligosaccharides are carbohydrate chains containing 3–10 sugar units. However, carbohydrates with up to 20 residues or even disaccharides. Oligosaccharides can be made of any sugar monomers, but most research has been carried out on fructooligosaccharides (e.g., oligofructose) and galactooligosaccharides (e.g., raffinose, human milk oligosaccharides). Few oligosaccharides are hydrolyzed and absorbed in the small intestine (e.g., maltotriose), but nearly all enter the colon intact (nondigestible oligosaccharides).
What are non - proteinaceous molecules ?
Amino acids are classified as non-protein when they are not part of the 22 such molecules that are translated into proteins by the standard genetic code. They are found in nature, both in biology and extraterrestrial chemistry.

According to Alfred Russel Wallace, disadvantageous traits are eliminated from the population by natural selection. This is the process of evolution as only the dominant individuals are able to reproduce successfully and their traits passed down generations.
However, today in the advent of improved technology in healthcare, more and more ‘disadvantageous traits’ are being maintained in the population due to advances in medicine that improve the survivability of these individuals – such as people with genetic disease like Parkinson’s.

Answer: D. Competitive exclusion
Explanation:
This is because the competitive exclusion theory states that two organisms that compete for the same resource can't co exist. It doesn't effect the carrying capacity.
