Answer:
Poriferans.
Explanation:
The evolution of the organisms has been occur from the simple organisms and leads to the evolution of the more complex organisms. This complexity arises due to the changing environment of the organisms.
The protozoans are the simplest organisms and all the other animal lineage has been derived from the porifera. The porifera are the cellular organisms that  do not have tissue level of organization and simple physiological system. Later, diverse and complex organisms arise from the porifera.
Thus, the correct answer is option (1).

<span>This is the condition under which he would classify them as belonging to different species - the two salamanders cannot mate to produce a fertile offspring. If these two lizards belonged to the same species, they would normally be able to breed and give birth to a fertile new "child." However, given that they are not of the same species, they cannot do such a thing, which is why this scientist classified them that way.</span>
        
                    
             
        
        
        
To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml
