Answer:
Pineal gland
Explanation:
The suprachiasmatic nucleus is the paired nucleus made of about 1000 neurons each in the hypothalamus. The suprachiasmatic nucleus is involved in maintaining the endogenous clock or the internal clock.
The suprachiasmatic nucleus controls the circadian rhythm by controlling the amount of melatonin. The melatonin is produced by the pineal gland from the serotonin and tryptophan precursors.  The hypothalamus thus controls the amount of the melatonin by regulating the pineal gland.
Thus, Pineal gland is the correct answer.
 
        
             
        
        
        
The correct answer is iron.  
The scientists from Britain discovered a soap with magnetic characteristics that could exhibit huge applications in the manner to fight against the damaging oil spills. In the mentioned soaps, the iron-abundant salts are supplemented to establish metallic centers inside the particles of the soap.  
After the solution is treated in a water source, a magnet was utilized to subjugate both the surface tension and gravity of the water, levitating the iron-rich scrubbing bubbles so that they can be withdrawn easily.
