The correct answer is medulla oblongata.
Medulla oblongata is the part of the central nervous system. It is the structure which continiues to spinal cord and represents the lowest part of the brainstem. Function of medulla oblongata is to control involuntary, autonomic functions. It contains centers for the heart and lungs, thus it regulates functions of breathing, heart rate and blood pressure.
Answer:
A 6H2O + 6CO2 → C6H12O6 + 6O2
Explanation:
The law of conservation of matter states that matter can neither be created nor destroyed in a system. In other words, when elemental matter undergoes a reaction, the amount of elements used must be equal the amount produced.
The equations in this question depicts the overall photosynthetic process where CO2 combines with H2O to produce C6H12O6 and O2. In order for this equation to obey the "conservation of matter", each individual element must be equal on both the reactant and the product side i.e. the equation must be balanced.
The equation that fulfills this is:
6H2O + 6CO2 → C6H12O6 + 6O2
Hence, it correctly describes the conservation of matter.

Answer:
By using periodic table.
Explanation:
By using periodic table the student can find out that which atom is more reactive because the arrangement of atoms on the periodic table occurs on the atomic number that shows the reactivity of atoms. Chlorine and bromines are members of same family but the chlorine is present above bromine in the group due to less atomic number. The reactivity of chlorine solution is higher than bromine solution due to unstable radical of chlorine.
