The percentage change of pH for the water is 56%.

In this exercise, you're required to calculate the percent change of pH for water from an experiment by using the necessary parameters (values).

In Chemistry, pH literally means the power of hydrogen ions and it's a measure of the molar concentration of hydrogen ions in a particular solution, thus, specifying the;

A pH scale measures the concentration of hydrogen ions in acidic and alkaline solutions. Typically, the pH scale is calibrated with a standard measurement that ranges from 0 to 14.

Note: The required parameters are missing from the question. Thus, let's assume some values to illustrate how to solve the question.

Assumed data:

pH at 0 drops = 2.5

pH at 5 drops = 1.1

Mathematically, the percentage change of pH would be calculated by using this formula;

[tex]Percent \;Change \;of \;pH = \frac {pH \;at \;5 \;drops\; - \;pH \;at \;0 \;drops}{pH \;at \;0 \;drops}[/tex] × [tex]100[/tex]

Substituting the values into the formula, we have;

[tex]Percent \;Change \;of \;pH = \frac {1.1 \;- \;2.5}{2.5}[/tex] × [tex]100[/tex]

Note: The negative sign must always be neglected when solving for percentage change.

[tex]Percent \;Change \;of \;pH = \frac {1.4}{2.5}[/tex] × [tex]100[/tex]

[tex]Percent \;Change \;of \;pH = 0.56[/tex] × [tex]100[/tex]

Percentage change of pH = 56%

Therefore, the percentage change of pH for the water is 56%.

Thomas Malthus

Explanation:

An article on the Principle of Population, written by Thomas Malthus in 1798, inspired Darwin's views as he grappled to comprehend what mechanisms could be during work to create evolution. Malthus proposed that populations of animals and plants, including humans, enlarged geometrically in quantities while the nutrients available only grew arithmetically. Thomas was also a key benefaction to Darwin's perception about the theory of limits put on the geometric growth of populations by nature.

Adaptations are characteristics that enable plants and animals to be successful in a particular environment. These adaptations come in a variety of forms, an example is camouflage (Mbgnet.net, 2015). Animals are able to camouflage to their environments to help them hide from their predators, or hunt for their prey. As well as keeping them safe while they sleep, and allow them to move around more freely.

Explanation:

As living beings that encounter every kind of traumatic event from paper cut to myocardial infarction, we must possess ways to heal damaged tissues. While some animals are able to regrow complete body parts following injury (such as the earthworm who grows a new head following bisection), humans are sadly incapable of such feats. Our means of recovery following tissue damage consists largely of repair rather than pure regeneration. Thousands of times in our lives, a meticulously scripted but unseen wound healing drama plays, with cells serving as actors, extracellular matrix as the setting and growth factors as the means of communication. This article briefly reviews the cells involved in tissue repair, their signaling and proliferation mechanisms and the function of the extracellular matrix, then presents the actors and script for the three acts of the tissue repair drama.
