I mole of water has an Avogadro number of molecules.
1 mole = 6.02 * 10^ 23 molecules.
6.02 * 10^ 23 molecules = 1 mole of water
1 molecule = 1/(6.02 * 10^23) mole of water
2.0 * 10^22 molecules would have = (2*10^22) * 1/(6.02*10^23)
= 0.033
2* 10 ^22 molecules of water would have 0.033 moles of water.
In a mixture of gases, the total pressure is equivalent to the aggregate of all the partial pressures of the single element of the gas.
It can be written as 
= P₁ + P₂ + P₃ and so on.
The partial pressure will be:
Option A. 0. 31 atm
Pressure can be estimated by:
<u>PV = nRT</u>
Where,
And,
Solving finally we get,
Therefore, 0.31 atm is the partial pressure of the hydrogen gas.

Answer: A change in the sequence of DNA bases--> Joining amino acids in sequence --> Appearance of characteristics
Explanation:
A mutation is a permanent shift or change from the normal DNA sequence that makes up a gene and affect traits which makes the sequence becomes different from what is commonly found in people. Mutations vary from distortion of a single DNA building block to a large segment of a chromosome.
When mutation occurs in a cell, for the mutation to affect the traits expressed by the particular cell, it must follow this sequence directly:
A change in the sequence of DNA bases--> Joining amino acids in the sequence --> Appearance of characteristics.
Answer : The density of the block is estimated to be, 
.
Explanation :
Density of the water, 
As we know that,
Buoyant force = 
where,
g = gravitational acceleration
volume of the block = v
density of the block = 
Weight of the Block = Buoyant force exerted by water
Thus, the density of the block is estimated to be, .
Many protons would bypass ATP synthase, resulting in a sudden decline in ATP synthesis.
