⁣Other organs include your brain, lungs, heart, liver, stomach, intestines, pancreas, and kidneys, and they're called internal organs because they're located on the inside of your body.

⁣A WORD or NAME formed from the letters, usually the first letters, of several other words: BBC from British Broadcasting Corporation, NATO from North Atlantic Treaty Organization. It is a kind of ABBREVIATION, with two forms: the INITIALISM (BBC pronounced 'bee-bee-cee'); the ACRONYM (NATO, pronounced 'Nay-toe').

⁣What is a simple definition for matter?


Matter is anything that takes up space and can be weighed. In other words, matter has volume and m****. There are many different substances, or types of matter, in the universe.

⁣In "word analysis" or "word study," students break words down into morphemes, their smallest units of meaning. Each morpheme has a meaning that contributes to the whole word. Students' knowledge of morphemes helps them to identify the meaning of words and builds their vocabulary.

⁣What are possessive nouns? Possessive nouns are used to denote ownership or to detail an aspect or attribute of something. If a phrase can be changed to say that a noun belongs to someone or something, then a possessive noun may be used. Remember, the possessive normally is placed in front of the item it owns.

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.://www.tutway.com/

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also, how does a physicist discuss speed as opposed to a police officer? And did you deserve that ticket? You can figure it all out with the help of Physics!

SUMMARY: This movie explains the biology of enzymes. Enzymes are protein catalysts that accelerate chemical reactions by lowering activation energy, playing a crucial role in processes like digestion and metabolism in all organisms. They bind to substrates at their active site, facilitating the transformation of reactants into products, and their function depends on factors like pH and temperature. However, changes in these environmental conditions can denature enzymes, reducing or destroying their activity, making them essential but sensitive players in biological systems.

My hope is that this video will catalyze lots of learning.

Enzymes LYRICS:
They're the protein catalysts in every organism
ENZYMES!
Through enzymatic action your metabolism's driven
ENZYMES!
In staphylococcus, jellyfish, tarantulas and trees,
They lower activation energy
Enzymes, in you and me now
ENZYMES!

You got 'em in your cells where they do cellular digestion,
ENZYMES!
You got 'em in your mouth and in your stomach and intestines
ENZYMES!
The thing an enzyme acts upon is called a substrate.
They fit like lock and key with complementary shape
Enzymes, speed up reaction rates
ENZYMES!

An enzyme binds its substrate at its active site
ENZYMES!
Bound together in a complex where they snuggle so tight,
ENZYMES!
New bonds will form and break due to the active site's chemistry
Reactants become products, it's the enzyme's specialty,
Product gets release enzyme repeats its action readily
ENZYMES!

Like any molecule an enzyme's shape defines its function.
ENZYMES!
Environmental change that changes shape leads to malfunction,
ENZYMES!
Every enzyme has a pH where it catalyzes best,
a pH change will set enzyme activity to rest.
Enzymes are so sensitive they're easily upset
ENZYMES!

More heat until a certain point increases their efficiency
ENZYMES!
But too much heat denatures them destroying their activity
ENZYMES!
That's why a fever running high's a dangerous situation,
All that heat can alter enzymatic conformation.
Keep it 98.6 for enzyme optimization
ENZYMES!

Enzymes in saliva will break starch into glucose
ENZYMES!
If you lack the enzyme lactase then you won't enjoy milk lactose,
ENZYMES!
Tay-sachs, galactosemia and PKU disease,
All caused by inherited enzyme deficiencies
ENZYMES, they're what everybody needs
ENZYMES!

Cell structure and organisation

⁣Every person has a blood type, (O, A, B, or AB) and an Rh factor, either positive or negative. The blood type and the Rh factor simply mean that a person's blood has certain specific characteristics. The blood type is found as proteins on red blood cells and in body fluids. The Rh factor is a protein that is found on the covering of the red blood cells. If the Rh factor protein is present on the cells, the person is Rh-positive. If there is no Rh factor protein, the person is Rh- negative.
The following are the possible combinations of blood types with the Rh factors:
Rh Positive Blood Types:
A+, B+, 0+ and AB+
Rh Negative Blood Types:
A-, B-, 0- and AB-
Rh factors are genetically determined. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
If a person has the genes + +, the Rh factor in the blood will be positive.
If a person has the genes + -, the Rh factor will also be positive.
If a person has the genes - -, the Rh factor will be negative.

⁣Question words, often called wh- words, are function words that can be used to ask open questions. Some words, such as who, which or where, can also be used to introduce relative clauses.

Addition is ⁣the action or process of adding something to something else.

Learning Outcomes:
- Name, describe, and identify the functions of the parts of the body.
- Describe how the parts of our body work together.
