The principal-agent problem could be defined by saying that it is an agent who benefits from the effort of others without having even participated in the joint effort. It is a concept that is to be linked more broadly to the problems of information asymmetry.
<span>The term moral hazard refers to a type of market failure where the existence of insurance against a certain risk increases the likelihood of the occurrence of the event causing the risk.</span>
<u>The right answer is:</u>
Principal-agent problem matches with 2
Asymmetric information matches with 3
Adverse selection matches with 4
Moral hazard matches with 1
        
             
        
        
        
During a dehydration reaction, two monomer molecules are covalently bonded to each other, with the loss of a water molecule. In this reaction, each monomer contributes part of the water molecule that is released during the reaction. This reaction is repeated as monomers are added to the chain one by one, making a polymer.
        
             
        
        
        
Answer: 
presence or absence of a protective covering over the ovule
Explanation:
In angiosperms, seeds develop from ovules and are enclosed in the ovary. So, their is the presence of protective covering making the seeds enclosed. 
On the other hand, gymnosperms have seeds that are borne on cones, so they are naked due to the absence of any protective covering over the ovule.
 
        
             
        
        
        
C. It would make it for difficult for animals to move around and seek resources in other areas. 
Explanation:
Small patches of protect land makes it difficult for animals to move around and see resources in other areas. 
Protected areas or conservation areas are locations that receive special protection because of the natural diversity found in them. 
- Protected areas in some places are the last refuge for animals and plant species for safety. 
- The larger a protected area is, the better and more advanced an organisms niche can be. 
- A small protected area limits the niches of roaming animals and makes it difficult to seek for resources out of their limited scope.
