What is Homeostasis?Homeostasis is defined as a state of stable internal, physical, and chemical conditions maintained by living systems that are optimal functioning conditions for the organism and includes many variables, such as body temperature and fluid balance, some being kept within pre-determined limits.
Homeostasis is the maintenance of optimal conditions for enzyme action throughout the body, as well as all cell functions which is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, homeostasis include the control of: Blood glucose concentration. Some example of homeostasis is the muscles begin shivering on a cold, snowy day.

Answer:Loess Hills and Sand Dunes
Friend me!!!!
Explanation:Loess is made of silt that were wind blown from vertical cliffs.
Sand dunes are basically hills of sand. They form when wind is impeded by a rock and it drops some of the sand as it hits the rock. Slowly the deposited sand builds up to form bigger dunes.
Hills since sand dunes are hills also, this is also considered a formation made by wind deposition.

WHY IS OXYGEN CLASSIFIED AS PURE SUBSTANCE AND AIR IS CLASSIFIED AS A MIXTURE?
CAN ANYBODY PLEASE HELP?
Answer:
I'm pretty sure it is because oxygen is a single atom and air has multiple atoms
Answer:
Here-
Explanation:
Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components.
Air isn't exactly pure its got all the gases mixed together, but when we breathe oxygen is pure because nothing else can make oxygen, its just O.
Air can still be air if it doesn't have carbon dioxide in it. It can still be air without water vapor. Also oxygen is a pure element on the periodic table.

Answer:
To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.
2. To familiarize students with experimental apparatus, the scientific method, and methods of data analysis so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.
3. To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic "errors." This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.
4. To learn how to write a technical report which communicates scientific information in a clear and concise manner.
5. To introduce new concepts and techniques which have a wide application in experimental science, but have not been introduced in the standard courses. These may require that the student consult additional textbooks.

Hope this helps :3
Yes, the percent daily value (% DV) is a useful tool, even for people who don't consume a 2,000-calorie diet.
What is the percent daily value?The percent daily value may be defined as the value which is usually calculated by dividing the amount in a serving by the total recommended daily amount.
It indicates the value of each nutrient in a serving of the food specifically. It gives an idea to the person how more he/she is already taken in terms of calories or may be short with respect to daily recommendation limits.
Therefore, it is well described above.
