[6] Calculate the percent change of pH for the water using the formula below. Show your work.
Percent Change of pH = 100 x (pH at 5 drops - pH at 0 drops) / (pH at 0 drops)
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;
Acidity of a chemical solution.Neutrality of a chemical solution.Basicity (Alkanility) of a chemical solution.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%.

Why is it impossible to go to the past?
Answer:
The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity. Mathematically one can go backwards or forwards in the three spatial dimensions. But time doesn't share this multi-directional freedom.Explanation:

Which statement about human population growth is FALSE?
a) From 1350 AD to the present, the world has experienced continuous population growth.
b) From 200,000 BC through 8,000 BC, the global population was low.
c) The global population is expected to peak at 7 billion, then begin decreasing.
d) The world population doubled between 1959 and 1999.
Which statement about human population growth is FALSE?
Choose: c) The global population is expected to peak at 7 billion, then begin decreasing.
The false statement is: The global population is expected to peak at 7 billion, then begin decreasing.
What is meant by population growth?
Population growth is the increase in the number of humans on Earth. For most of human history, our population size was relatively stable. But with innovation and industrialization, energy, food, water, and medical care became more available and reliable.
Was there population growth in 2020?Population gains attributable to natural increase rose as high as 1.1 million in 2016-17, but dropped to 677,000 in 2019-20 and then again to 148,000 in 2020-21.

I believe that the answer you are looking for is letter D, 11.0 grams/milliliter.
Solution/Explanation:
Writing out the formula for the density, using mass and volume,
D=m/v
Substituting the given values of the variables,
D=33.0 grams/3.0 milliliters
33÷3=11.
So, therefore the final answer is the letter D, 11.0 grams/milliliter.

this type of tissue has excellent ability to regenerate contains many nerve but has no blood supply
Answer:
there u go
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.
Key words: tissue repair, regeneration, scarring, wound healing, growth factors, extracellular matrix, stem cells

True or false: The scientific method is a cycle. If your experiment does not support your hypothesis, you should change your hypothesis and try again.
i think it is true
Explanation:
In most cases, the scientific method is an iterative process. In other words, it's a cycle rather than a straight line. The result of one go-round becomes feedback that improves the next round of question asking.

Besides Darwin, the theory of evolution by means of natural selection was also independently proposed by:
Answer:
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.

Hi, There! The Correct Answer Is Below!
Thomas Malthus is your Answer

What are the adaptations of a seablite to survive its environment
Answer:
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.
