Answer:
true
Explanation:
The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8.
Answer:
Option (2).
Explanation:
Neural impulse may be defined as the the way by which nerve cell can communicate with each other in the body. These nerve impulse travels in the form of electrical signals in the neurons.
The strength of the nerve impulse changes in the different neuron. The neural impulse in a single neuron has the same strength each time when the neuron fires.
Thus, the correct answer is option (2).
