It's a tri structure made up of two or more separate polypeptide chains that work together to form a single functional unit. The – anti interactions and disulfide bonds that stabilize the resultant multimer are the same as in the tertiary structure.
 
        
             
        
        
        
Answer: <u>Genetic Modification of crop plants.</u>
Explanation:
Genetic modification alters the genome of an organisms through the use of biotechnological tools and advancements in molecular biology. Usually, DNA is swapped among organisms, and between species;  this is called transgenes. These altered plants are usually called transgenic organisms.
Some plants can be modified in several ways to meet global food security needs. These include:
-drought tolerance-plants grow in arid conditions with minimal water
-increased yield- plants produce more crop per input 
 
        
             
        
        
        
Answer:
Secondary
Explanation:
There are several levels of prevention. You might confuse this with primary prevention. Primary prevention is preventing infection, so it has to be done before the patient caught the disease.
The needle-exchange program aims to reduce the spread of blood-borne disease(HIV, hepatitis, etc) from the multiple usages of the same needle. Since the disease already exists, this will be secondary prevention.
