D) laboratory experiments because every experiment needs a control and a variable.
Answer:
Option B, 
hectoliters
Explanation:
As we know that in one hectoliter there are ten decaliters
hectoliter 
decaliters
or
decaliters 
hectoliter
For converting any small unit into a large unit it is to be divided by number of units in large unit.
Thus,
decaliters in terms of hectoliter is equal to
Hence, option B is correct
Answer:
Membrane bound organelles, such as a nucleus and mitochondria.
Answer:
Both
Explanation:
Baking soda is the common name of sodium bicarbonate or sodium hydrogen carbonate. Both the empirical and molecular formula of sodium bicaronate is NaHCO3 .
Baking soda is soluble in water and has a molar mass of almost Molar mass: 84.007 g/mol.
If we look at molecular formula of NaHCO3, it has molar ratio of 1:1:1:3 and we can say that every thing in this molar ratio make whole mass as : 23g +1 g +12 g+48 g= 84 grams.
Since we know that empirical formula demonstrates the simplest ratio of elements present in a compound and molecular formula demonstrates the total molar ratio of each element in a compound, hence we see that its empirical and molecular formulas both are already simple because they have simplest ratio which cannot be simplified further.
Hope it help!
