Explanation:
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:
explain six changes of the man life after begining of agriculture
Nancy the neuron has just fired an action potential. Now she cannot fire another action potential until she resets her electrical potential. She is in a refractory period. The refractory period starts after the hyper-polarization of the neuron. In this phase the neurons is inhibited of generating further action potentials, and the recovery to resting potential of the neuron membrane begins with the potassium ions slowly leaking into the cell.
