Answer:
pH meter and pH paper.
Explanation:
There are a few other ways that are commonly used, including titration, but most are tedious and require detailed hands-on work. A pH meter is normally assisted by the use of a computer or a digital user interface. The use of pH paper can be likened to the use of a Galileo thermometer.
This statement means that evolution has happened by getting the genes of the right trait expressed at the right time to help adaptability.
Explanation:
Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.
We can conclude that all features are not adaptable some are the results of genetic drift or mutations.
In case of cheetah, the faster running genes would have been there they got expressed over the period of time for better adaptability.
Answer:
Option (D)
Explanation:
The entropy is usually defined as the measure of the total thermal energy of a system per unit temperature. This amount of energy is used in performing valuable work. In simple words, it can be said that entropy is related to the disorder or degree of randomness of a particular system. This entropy concept gives proper information regarding the direction along which natural change occurs and is frequently observed in many present-day events.
Thus, the correct answer is option (D).
