The posttranslational alterations of proteins may include the addition of polysaccharides to proteins (Option 4).
<h3>What are posttranslational alterations of proteins?</h3>
The posttranslational alterations of proteins are different modifications in the protein sequences in order to activate their functions and or suppress them.
One of the most common posttranslational alterations of proteins is phosphorylation, which occurs at specific amino acid residues and it is able to activate or deactivate proteins in order to change the signaling pathway associated with their functions. Polysaccharides can also be added to proteins in order to change their functional states.
Therefore, with this data, we can see that the posttranslational alterations of proteins are able to modify the functional properties of a protein and polysaccharide addition in one of these types of modifications that both structural proteins and enzymes suffer to activate an or deactivate them.

Answer:
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.
Explanation:
Answer:
B. When there are limited resources
Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
