I would say the answer is C.

Cell theory states that living things are composed of one or more cells, that the cell is the basic unit of life, and that cells arise from existing cells.

As you can see, there’s more to the cell theory then just the answers provided.

Morgarella [4.7K]

Answer:

Novobiocin target DNA GYRASE of gram positive bacteria.

Explanation:

Novobiocin is a bacteriostatic(slow down bacteria growth) or bactericidal i.e it kills bacteria , narrow spectrum antibiotics that target DNA GYRASE of gram positive bacteria. It acts by inhibiting the bacteria DNA gyrase hydrolysis thereby by interfering with the metabolic activities of bacteria. It is also a weak catalytic inhibitor of mammalian. Novobiocin inhibit DNA gyrase and topoIV by binding to the ATP pocket of GyrB and ParE, respectively.The Streptomyces strain that produces Novobiocin and it is more effective on gram positive bacteria that gram negative bacteria because gram negative bacteria are resistant to it.

For each of the formulas, classify the formula as either an empirical formula, a molecular formula, or both. NaHCO3 empirical mo
shutvik [7]

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!
