⁣Mixtures can be separated using a variety of techniques. · Chromatography involves solvent separation on a solid medium.

⁣“Expository” means “intended to explain or describe something.” An expository essay provides a clear, focused explanation of a particular topic, process, or set of ideas. It doesn't set out to prove a point, just to give a balanced view of its subject matter.

⁣An illustration is a decoration, interpretation or visual explanation of a text, concept or process, designed for integration in print and digital published media, such as posters, flyers, magazines, books, teaching materials, animations, video games and films. An illustration is typically created by an illustrator.

What is Homeostasis? | Physiology | Biology | FuseSchool

Homeostasis is a term first defined by Claude Bernard in 1865. It means maintaining a constant internal environment.

Senses all around the body are measuring various things and sending the information back to the brain. The brain then does its best to keep all these things stable and constant to keep the body working properly. Homeostasis is maintaining a constant internal environment.

What kind of things need to be kept constant in the body? It's very important to keep our temperature the same, at around thirty seven degrees Celsius. You can find out more about this in the video on temperature regulation. You also need to keep the levels of sugar in the blood constant along with levels of ions and water. Your blood pressure needs to be carefully monitored along with the amount of waste in the blood such as carbon dioxide and urea.

Let's say one of these factors goes too high or low, what is the brain going to do to get it back to normal levels? The answer to that is negative feedback. Negative feedback is the process whether the brain uses either a hormone or the nervous system to send a signal to the part of the body that can rectify the problem. For example, after you eat a meal with your blood sugar level increases. This is detected, and the pancreas will release a hormone called insulin that causes the sugar to be stored in the liver. The blood sugar level will then return to normal.

Negative feedback is the leap from which the body takes a stimulus, reacts by responding accordingly and brings the body back to the normal levels.

So why is homeostasis so important? Our metabolism, which is all the chemical reactions in our bodies that keep us alive, is controlled by enzymes. These enzymes only work in very specific conditions. If these conditions change, they could stop working and we could die.

Luckily, all of this happens without you having to think about it. If you had to do it yourself, you would have to spend all day and night just trying to keep all these things constant and we'd have no time to doing fun like watch videos of cats on the Internet.

#PunctuatingSimpleLetterTopics Covered:Writing a simple letterParts of a letterPunctuating a simple letterRules for writing a simple letterI hope you liked our video.Kids should spend time watching informative videos and expand their knowledge day by day.Kids retain what they see in audio-visual lessons so make them watch informative videos rather than cramming things.If you want to learn any topic, please free to write to us, we will upload the video to help you out as soon as possible.We can also create a customized u tube playlist for the topics you want to learn.Your feedback is important to us.Stay connected with us:tutwayhelpdesk@gmail.comYouTube: https://www.youtube.com/channe....l/UCL-KeqwBmYvEBpAiU https://www.facebook.com/tutwa....y/https://www.tutway us:Welcome to Tutway.A unique platform where learning is fun.Now there is no distinction between kids’ fun time and study time.At Tutway, we believe in a very simple idea that audio-visual learning is the most effective tool for grasping knowledge. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons as compared to reading from books.That's when Tutway comes to the rescue.Tutway is a supplementary education program where kids can learn at their own pace. The students can watch animated videos that are so meticulously made that they can understand even the most complex concepts very easily. There is a question bank at the end of each video where students can answer those questions multiple times and test whether they have grasped knowledge completely or not.We have information systems embedded in the program where parents can monitor real-time performance of their kids and get up to date information about their performance, including quizzes attempted and the marks got in each quiz, both in tabular and graphical formats. Regular reports are e-mailed to the parents so that the parents can analyze their kids’ performance.If we want to learn high-level concepts, we should have a clear understanding of the basic concepts. For instance, if kids don't know about addition and subtraction, they cannot do multiplication, and if they don't know about multiplication, they cannot do division, and if they don't have knowledge of these four basic operations, Algebra cannot be done by them, and it goes on and on.The same applies to the English language if kids don't have sound knowledge of grammar and vocabulary; it becomes extremely difficult for them to have their communication skills.Knowledge of the scientific concepts is also required for observing physical, chemical, biological phenomena happening all around us.That is why; Tutway has thousands of animated videos on Maths, English, and Science to clear the basics of these subjects. It perfectly suits most of the educational needs of most of the students, regardless of their learning abilities.So hurry up, download the Tutway app and book a free-demo cl**** to make education interactive and fun experience.

⁣Words that are hard to read, write, spell and understand are considered to be difficult words in English.

⁣The mesophyll is found between the upper and lower epidermis; it aids in gas exchange and photosynthesis via chloroplasts. The xylem transports water and minerals to the leaves; the phloem transports the photosynthetic products to the other parts of the plant.

⁣A composite shape can be defines as a shape created with two or more basic shapes. We often refer to composite shapes as compound and complex shapes as well.
We see composite shapes every day. The shape of your curved bookcase, the mouse you are scrolling, and the bag you are carrying are all composite shapes.

⁣Suffixes are letters added to the end of a base word to change its conjugation, word type, or other grammar properties like plurality. For example, take the noun strength: You can add the suffix –s to make it plural (strengths) or the suffix –en to change it into a verb (strengthen).

⁣Meaning of synonym in English. a word or phrase that has the same or nearly the same meaning as another word or phrase in the same language: The words "small" and "little" are synonyms. 'Wrong' is a synonym for 'incorrect'.

⁣The past participles of regular verbs are typically formed by adding the suffix “-ed” (or “-d” if the word already ends in “e”). The past participle of a regular verb is identical to its past simple form (e.g., “canceled” and “canceled”).

⁣A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link.

⁣Making inferences means choosing the most likely explanation from the facts at hand. There are several ways to help you draw conclusions from what an author may be implying. The following are descriptions of the various ways to aid you in reaching a conclusion. General Sense.

Listen to this story read by Miss Measures. Remember to pause the video to answer the questions.

Just one third of countries have achieved all of the measurable Education for All (EFA) goals set in 2000. Only half of all countries have achieved the most watched goal of universal primary enrolment. An extra $22 billion a year is needed on top of already ambitious government contributions in order to ensure we achieve the new education targets now being set for the year 2030.
These are the key findings of the 2015 EFA Global Monitoring Report (GMR) “Education for All 2000-2015: Achievements and Challenges”, produced by UNESCO which has tracked progress on these goals for the past 15 years.
