Answer:
The correct answer is carbohydrate chain.
Explanation:
Plasma membrane contain various proteins such as peripheral proteins,transmembrane proteins,GPI anchored proteins.Among them some protein contain carbohydrate chain basically oligosaccharide chain which is arranged in the extracellular portion of the plasma membrane.
The principle function of these oligosaccharide side chains is to detect various chemical and biochemical signals from outside the cell .

Oh I know this, It narrows down its characteristics here is an example:
The first step in the key will be organized the following way:
1. a. wings covered by an exoskeleton
b. wings not covered by an exoskeleton
Next, the statements need to lead the observer to the next step to narrow the identification further:
1. a. wings covered by an exoskeleton go to step 2
b. wings not covered by an exoskeleton .go to step 3
Step 2 needs to consist of a pair of statements that will allow for the identification of the ladybug and the grasshopper:
2. a. body has a round shape .ladybug
b<span>. body has an elongated shape .grasshopper</span>
Explanation:
Planarians are a group of Turbellaria, free-living flatworms that capture their food via a process of wrapping around it, entangling it in slime, and pinning it down before a prey into a gastrovascu lar cavity where free-living flatworms that capture extends from the mouth, bringing the prey into a gastrovascular cavity where free-living flatworms that capture extends from the mouth, bringing the digestion occurs.
