They are used for them to adapt to the environment
Yes they can to create new tissues
To be pregnant, an equilibrium in ph and chemical contents of the uterus and the outside environment has to be maintained, to prevent any reactions of the chemical sustances taken in by the person pregnant and the baby *has something to do with concentration gradient, hence yes, pregnancy can count as homeostasis
Answer:
The pH of a solution containing 0.1 mM H+ is 4
Explanation:
The pH of any solution is given by the following mathematical equation -
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given
= 
Substituting the given value in equation (A) , we get -
![pH = -log[10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)

Hence, The pH of a solution containing 0.1 mM H+ is 4
