Answer:
C. CH4 + 202 – CO2 + 2H20
Explanation:
CH4+O2-CO2+H20
The above equation represents combustion of methane to produce carbon-dioxide and water.
One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.
The balanced chemical equation is:
CH4+202-CO2+2H2O
This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.

Answer:
DNA
Explanation:
Experiments such as the one by Frederick Griffith in 1928 showed that DNA is the hereditary molecule. How showed that virulent bacterial species could transfer DNA to avirulent species and make them virulent too. This means that DNA determines the characteristic of the individual and can be passed down or across generations.
Living -
Respond to stimuli
Grow and develops
Used energy
Not living-
Non cellular
I am not sure about the reproduces only in a host cell. I would say living but I’m not 100% sure
because they are both composed of 2 diffrent materials like how noses are made out of same material as a sharks "skin"
