Answer:
So first understand that empirical formula refers to ratio of different atoms in lowest integer form.
To calculate this let's make mol C as our default ratio of 1* and divide everything by 0.528 mol.
Na 1.06/0.528 = 2.00757575758
C 0.528/0.528 = 1
O 1.59/0.528= 3.01136364
Na2CO3
It's sodium carbonate
Answer
The organism should be name as bacteria.
Explanation
Peptidoglycans is the characteristics features of bacterial cell its absent in cell wall of archaea, fungi and plant cell. Bacteria can also make amino acids. There are some bacteria who can prepare their own food in the presence of sunlight, i.e purple phototrophic bacteria, green sulphur bacteria, green filamentous bacteria etc. these bacteria contain photosythertic pigments called bacteriochlorophyll.
The answer is true cause the movement of water and small particles through a membrane due to hydrostatic pressure, from high pressure to low pressure.
The universe contains organized structures on all different scales, from small systems like the earth and our solar system, to galaxies that contain trillions of stars, and finally extremely large structures that contain billions of galaxies.

Answer:
The correct answer is - osmosis.
Explanation:
Paramecium lives in freshwater like the Potomac River which is hypotonic to the cytosol of the paramecium. Paramecium uses contractile vacuoles to transport the water from the lower concentration (outside of the cell) to a high concentration of solvent to the inside of the cells.
This process of cell transport is carried out by osmosis as their cytoplasm contains a higher concentration of solutes outside the cell. This excess water is collected into vacuoles called contractile vacuole that swells and finally internalized the water to the outside of the cell.
Thus, the correct answer is - osmosis.
