Answer:
TO TEST SUPPLY OF WATER QUALITY OF THE LOCALITY Excessively high and low pHs can be detrimental for the use of water. High pH causes a bitter taste, and water pipes.
Alkaline water turns red litmus paper blue. Acidic water turns blue litmus paper crimson. Pure or neutral water won't modify the litmus paper's color.Therefore, it can be used to test the quality of the drinking water.
What is pH?
A quantity that expresses the degree to which a substance or solution is acidic or basic. On a scale that ranges from 0 to 14, pH is measured. A pH value of 7 is considered neutral on this scale, which indicates that the substance in question is neither acidic nor basic. If the pH value is lower than 7, the substance in question is more acidic, and if the pH value is higher than 7, it indicates that the substance in question is more basic.
It is recommended that you consume water that is neither overly acidic nor overly alkaline, as well as water that is both clean and pure. The Environmental Protection Agency of the United States suggests that the pH level of drinking water should fall somewhere in the range of 6.5 to 8.5. The pH reading of the vast majority of ground and surface water should fall somewhere within this range.

to the cell?
Answers
Answer:
But now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic
Explanation:
hope it helps :P
The cell will shrink as the solvent from low concentration solute will move towards the high concentration solute.
What is osmosis ?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
Since the solute concentration in the muscle cell is just 2%, and the muscle cell is dipped in a solution that contains 5% solute, the solvent will flow from the muscle cell into the solution. This will result in the muscle cell becoming smaller until the concentration of solutes on both sides is equivalent.

How does this question represent the law of conservation of energy that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
Answers
You need to put this into your own words, or else your school system will detect you copied from a source named Brainly.
Anyways, the law of conservation of energy is exactly what it says. Energy cannot be created nor destroyed. All they do is rearrange.
Now, for photosynthesis, it's an interesting thing. Photosynthesis takes the energy from the sun's light to produce sugars/carbohydrates. The sun's energy just got reused. It also uses water, which comes from the soil/ground. This simply, reuses the water. During photosynthesis, it also absorbs the carbon dioxide from the air. The carbon dioxide like everything else listed, got reused.
Meaning, energy does not leave. It endlessly works for different purposes. And as you should know, all of the water on the planet has been here since the dawn of time.
Hopefully this makes sense. Have a nice day!

which molecule is important in regulating cell membrane fluidity?
Answers
Answer:
cholesterol plays a distinct role in determining membrane fluidity.
Cholesterol has a specific impact on how fluid a membrane is. With their polar hydroxyl groups adjacent to the hydrophilic head groups of the phospholipids, cholesterol molecules enter the bilayer.
How does cholesterol regulate cell membrane fluidity?The phospholipid bilayer's random distribution of cholesterol molecules aids the bilayer's ability to remain fluid under a variety of environmental conditions.
Cells control membrane fluidity by modifying the lipid composition of the membrane. A lipid bilayer's fluidity fluctuates according to temperature. Lipid bilayers become more fluid, porous, or leaky at increasing temperatures (like butter melting on a hot day).
Cholesterol makes the cell membrane less fluid at higher temperatures and more fluid at lower temperatures.
Therefore, cholesterol is the chemical in the plasma membrane that has an impact on the fluidity of the membrane.

According to Kepler's second law of motion, which statement describes the area
swept out py a line between a planet and the sun?
It is constant if the planet moves at a constant speed.
O It increases as the planet moves away from the sun.
O It is constant for equal times.
OIt increases as the planet approaches the sun.
Answers
Answer: It is constant for equal times
Explanation: Just did the assignment
According to Kepler's second law of motion it is constant for equal times. The correct option is C.
What is Kepler's law?Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, characterize the orbits of planets around the Sun.
The speed of a planet in an elliptical orbit around the Sun is described by Kepler's second law of planetary motion.
It states that a line drawn among both the Sun as well as the planet shuffles equivalent regions in equal amounts of time.
As a result, the planet's speed increases as it approaches the Sun and declines as it fades away from it.
Kepler's laws of planetary motion represent a watershed moment in the transformation from geocentrism to heliocentrism.
They establish the first quantitative link among the planets, together with Earth. They also represent a time when the important questions of the day were changing.
Thus, the correct option is C.
