Answer: why it is hard to use dichotomous key in the lab are;
If the organisms you want to use it for are similar.
If you can't see the little characteristics posses by the organisms you are using it for.
If all the pictures does not reveal all the important features of the organisms.
It is very difficult to use it to determine the anatomical structure.
Explanation:
Dichotomous key is an important method that is use in biology to identify organisms by separating or dividing the organisms into two groups.

Answer:
The pH remains constant
Explanation:
The pH value of Mitochondrial matrix = 7.8 while the pH of the intermembrane space of the mitochondria = 7.0–7.4
The presence of the hydrogen atoms makes the mitochondrial matrix acidic and hence reduced the pH value but the pH of inner and outer matrix is maintained equal to each other thus as the H+ ion increases, the base concentration increases thereby pushing H+ to the inter membrane space and hence producing ATP.
