7. Phosphate Buffered Saline (PBS) buffer requires three components; 0.0017M KH2PO4, 0.0052M Na2HPO4, and 0.15M NaCl. Calculate the volume of stock solution needed for each component in order to make 1L of PBS. Below are the stock solution concentrations for each component. Finally, include the amount of dH20 needed to bring the solution up to 1 L. Show all calculations. 1.7M KH2PO4 stock solution
5.2M Na2HPO4 stock solution
1.5M NaCl stock solution​

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

i think the answer is c hope this

your answer would be a, maximum exploitation of resources.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
