Answer:
Here's what I get
Explanation:
Per the above explanation, pH means "power of hydrogen ions."
The concentration of hydrogen ions is a measure of the acidity of a solution. A higher concentration represents a more acidic solution.
The definition of pH is
pH = -log[H⁺]
Thus, pH is a measure of the hydrogen ion concentration.
The more negative the pH, the greater the Potenz of hydrogen ions.
Planting the same crop in the same place each year zaps nutrients from the earth and leaves soil weak and unable to support healthy plant growth. Because soil structure and quality is so poor, farmers are forced to use chemical fertilizers to encourage plant growth and fruit production.
The answer is

The interdependence
of body systems is essential because all systems work together to maintain
homeostasis. Homeostasis in body systems refers the regulation of internal
conditions keeping it stable and relatively constant. In humans this refers to
its ability to maintain stability in its internal environment while responding
to changes in external conditions. It serves as a sensor that detects changes
in the conditions that need to be regulated to meet the demands of the
condition and give the necessary feedback. Regulation of body temperature and
the balance between acidity and alkalinity are examples of homeostasis in the
human body.</span>
