Answer:
The correct answer would be B. thrombocytes.
Thrombocytes, also called platelets are the components of the blood which play important role in the process of hemostasis.
Hemostasis is the process of preventing the flow of blood from the damaged site or damaged blood vessel. It is the first stage involved in the healing of the wound.
Platelets form the platelet-plug at the site of damage which in turn activates another blood clotting factor fibrinogen. 
Fibrinogen gets converted into an active fibrin (insoluble) which forms the meshwork like structure to trap more and more platelets and red blood cells. It results in the formation of a clot which completely seals the cut or damaged site.
 
        
                    
             
        
        
        
Answer:
Active genotype - environmental effects
Explanation:
There are primarily three types of co-relation between genotype and environment which are as follows –  
a)	Passive genotype –environment effect – This depicts the relationship between the genetic characteristics acquired by a child from his/her parents and the environment in which he/she is raised.  
b)	Reactive genotype –environment effect – This represents a relationship between genetically acquired behaviour from parents and the reaction corresponding to such behaviour.  
c)	Active genotype –environment effect – This represents a relationship between genetic tendency of an individual and the environment condition selected by an individual .

No, although they can skip generations, they do not always. It is based on the type of genotype that is with the recessive gene. They can skip generations because a dominant phenotype can be produced by either a homozygous dominant trait or a heterozygous genotype.
        
             
        
        
        
Because they need it to get protein and create it. Protein helps the plants grow.
