Answer:
E.
Explanation:
The atomic radii increase in size down the group as the number of quantum shells and subshells increase with increasing atomic number.
Answer:
Option 2, Half of the active sites are occupied by substrate
Explanation:
Michaelis-Menten expression for enzyme catalysed equation is as follows:
Here, is Michaelis-Menten constant and [S] is substrate concentration.
When [S]=Km
Rearrange the above equation as follows:
when [S]=Km, the rate of enzyme catalysed reaction becomes half of the maximum rate, that means half of the active sites are occupied by substrate.
Therefore, the correct option is option 2.
The sea level would rise by some 50 meters.
Explanation:
If the earth's temperature increases by 3 degrees the north and south pole would experience the ice melt at high speed.
The life will get difficult on the plains.
The extinction of some species will happen.
The sea level would rise by 50 meters. The increased sea level will cause depletion of habitat from plants and animals.
The floods will occur, land erosion, soil for agriculture land will get contaminated with the salt.
