The given blank can be filled with enzymatic molecules.  
Enzymes refer to biological molecules or proteins, which function as catalysts and assist the composite reactions to take place everywhere in life. The enzymes generally end with the suffix - ase. For example, proteases, which functions to dissociate the peptide bonds between the amino acids.  
Enzymes are big molecules, which accelerate the rate of chemical reactions within the cells, and like all other kinds of proteins, they comprise lengthy chains of amino acids.  
 
        
             
        
        
        
Answer:
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

Oviparity is a mode of reproduction in which young, developed in fertilized eggs, laid outside the mother's body. This mode of reproduction is found in most reptiles and all birds. 
Viviparity means that their young develop inside the mother's body and are born alive. This is the mode of most mammals. 
<span>Ovoviviparity is similar to viviparity in that there is internal fertilization and the young ones are born alive but differ in that there is no placental connection, the young are fed by egg yolk. This is found i</span><span>n </span><span>seahorses, for example.</span>
