<span>One observation would be the physical size of Russia compared to other countries, despite a lack of visible borders from space. In addition, part of Russia's outline would likely be obscured by the various clouds and objects in the stratosphere; this would allow the astronaut to view potential cloud and weather patterns on earth. Also, an astronaut could see outlines of Russia's geography such as mountain ranges.</span>
        
                    
             
        
        
        
Answer: Option 4.
The fresh water is hypotonic and the salt solution is Hypertonic.
Explanation:
Hypotonic solution is a solution that have little dissolved solutes i.e low osmotic pressure compare to other solution. When a cell is put in hypotonic solution, it take in water and the cell swell up and it does not burst due to it's cell wall thereby becoming turgid or hard.
Hypertonic solution is the solution where the concentration of solute is higher outside the cell than inside the cell. Example is saline water.when a cell is placed in Hypertonic solution it will shrinks because it losses water.

Answer : The dissociation constant of the PFK‑inhibitor complex is, 5 µM
Explanation :
The expression for reversible competitive inhibition when apparent Km affected by addition of the inhibitor is:
![K_m_a=K_m[1+\frac{I}{K_i}]](https://tex.z-dn.net/?f=K_m_a%3DK_m%5B1%2B%5Cfrac%7BI%7D%7BK_i%7D%5D)
where,
 = apparent value = 52 µM
 = apparent value = 52 µM
 = Michaelis–Menten constant = 40 µM
 = Michaelis–Menten constant = 40 µM
I = inhibitor concentration = 1.5 µM
 = dissociation constant of the PFK‑inhibitor complex
 = dissociation constant of the PFK‑inhibitor complex 
Now put all the given values in the above formula, we get:
![52\mu M=40\mu M[1+\frac{1.5\mu M}{K_i}]](https://tex.z-dn.net/?f=52%5Cmu%20M%3D40%5Cmu%20M%5B1%2B%5Cfrac%7B1.5%5Cmu%20M%7D%7BK_i%7D%5D)

Therefore, the dissociation constant of the PFK‑inhibitor complex is, 5 µM
