Answer:
Fibrous  is the type of joint involved.
Explanation:
Diarthrosis is present at articulating bones which is responsible for the movement. Surrounding synovial capsules identifies it. synovial capsules which secretes synovial fluids to nourish and lubricate the joints while it acts as a shock absorber, surrounds the bones of synovial joints. 
Smooth, hyaline cartilages which is of glass like, reduces the friction while movement and are present at the lower of the joint bones. this synovial cavity and regular, dense connective tissue which is responsible for the formation of articular capsules related with accessory ligaments.
 
        
             
        
        
        
Answer:
Predator-prey relation.
Explanation:
A predator is defined as an organism that hunts another individual, whereas a prey refers to the organism that is eaten by the predator. They tend to co-evolve (evolve together). <u>The prey is essential for the predator to survive, while the predator controls the prey populations by hunting some of the individuals.</u>
Predator-prey relations are interactions that occur between two species where one species (prey) represents a food source for the other species (predator).
The turtle (prey) is essential for the survival of the jaguar (<em>Panthera onca)</em>, while the jaguar controls the populations of turtles by preying upon them. Therefore, this is a predator-prey relation.
 
        
                    
             
        
        
        
Answer:
Bacteria
Explanation:
Bacteria constitutes large group of unicellular organisms that lacks membrane bound organelles and constitute cell wall. Bacteria are used for the production of recombinant proteins.
Bacteria can be selected easily for the recombinant protein formation. The plasmid of bacteria is helpful for the integration of desired genes and the production of protein. The bacteria culture can be maintained easily in the laboratory. The different strains of bacteria with different traits can be used for the production of different recombinant proteins at low cost. 
Thus, the correct answer is option (1).
