Answer:The ratio of the concentrations of and when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid =
Concentration of HA= 0.5 mM
Concentration of = 0.1 mM
pH = 6.16
First we have to calculate the value of .
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
To calculate the ratio of the concentrations of and when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
Thus the ratio of the concentrations of and when the buffer has a pH of 7.02 is 0.69
The acetabulum is the cup-like structure where the femur articulates. The head of the femur is the specific structure which articulates in the acetabulum.
Answer:
Natural selection
Explanation:
this is where the term "survival of the fittest" comes from. The toughest survive and make offspring and the weak don't.
Answer: The correct answer is -
D) in a host, it is capable of reproduction.
Explanation:
Virus can be described as a microscopic, infective, non living agent that typically possesses genetic material (DNA or RNA) that is surrounded by a proteinaceous coat (capsid).
It can not replicate by its own and thus it uses host machinery for replication. In other words, it multiplies within host organism. This is the reason that it can be called as living.
Thus, option D) is the right answer.
