Learn how Meiosis is different than Mitosis.
To begin with What is the goal of mitosis and meiosis?
They both create new cells. Both mitosis meiosis start with diploid cells.
Mitosis creates body cells that are diploid. diploid means they have two sets of chromosomes. In humans each body cell has 23 pairs of chromosomes or 46 total.

Meiosis also creates new cells but these cells are gametes which for males is sperm cells and for females it is egg cells. These cells are haploid which means they have one set of chromosomes.

Division can be done instantly using this amazing math trick!
Moving from left to right trick can be done accurately and faster then a calculator.
In the example provided we will divide 9 into 316249. Amazingly to do this we will not use any division, nor will you have to use your nine times table, instead we will use addition to answer this division question!
This video is part three in a series of three, and leads to how to do long division the fast and easy way!

How do ecosystems change over time?
Ecological succession, also called Biological succession occurs when one ecological community changes into another.
There are two main types of ecological succession.
Primary and Secondary Succession.
Primary Succession occurs when there is no soil and the new community has to start without any soil.
Secondary succession occurs when an event destroys an area but the soil remains.
The pioneer species are the first plants to appear in the new ecosystem.

In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years' War, which is often called the French and Indian War in the US, laid a lot of the groundwork for the Revolution. More confusing? Why does this war have two names? Why were the French and Indians fighting each other? The Seven Years' war was actually a global war that went on for nine years. I think I'm having trouble making this clear. Anyway, the part of this global war that happened in North America was the French and Indian War. The French and Indian tribes were the force opposing the British, so that's the name that stuck. Let's get away from this war, as it makes my head hurt. Other stuff was going on in the colonies in the 18th century that primed the people for revolution. One was the Great Awakening. A religious revival was sweeping the country, introducing new ideas about religion and how it should be practiced. At the same time, thinkers like John Locke were rethinking the relationship between rulers and the ruled. So in this highly charged atmosphere, you can just imagine what would happen if the crown started trying to exert more control over the colonies. The colonists would probably just rise up, right? We'll see what happens next week.

Companies are organizations which dedicate themselves
to producing goods or services in exchange for a benefit,
or in other words, for money.

The goods are the products which the companies make.
Some companies make candy, clothes, books full of
stories, and there are companies which make cars. There
are loads of companies all dedicated in manufacturing all
sorts of different products!

If you look around you, all you see has been produced in a
company.

There are also companies which provide services, such as
the transport companies which take us from one place to
another, the hairdressers who don’t sell us anything but
cut our hair and brush it, giving us a service as well as
making us look preIy. Check out all these different hair
styles!

There are a great number of services offered by
companies.

To carry out these activities, companies need material and
human resources. The material resources are what the
companies need to manufacture or produce something.
For example, a bakery needs flour, ovens, utensils,
vehicles to deliver the bread to the clients etc, etc…
A company which produces fruit juice would need fruit, a
juice squeezer, refrigerators, packaging, and trucks for
transportation…

So as to create a product one needs many resources and
that is why we should never waste anything and we must
recycle the juice container for example.
The human resources are the people who work in the
companies. These people are the employees and
employers.

The employers are those who create a company, direct it
and make sure all is working correctly, besides they are
the ones who are risking their money.

The employees are the people who are working in the
company in exchange for a salary, from their pay sheet,
meaning money.

An enterprise´s spirit is one who plans projects and brings
them to life. If you want something, you can have it!
Well now we know what a company is all about. In the
next video we will learn more about different types of
companies.

A basketball and a 5kg medicine ball are dropped simultaneously. Which one hits the ground first? It seems obvious that the heavy one should accelerate at a greater rate and therefore land first because the force pulling it down is greater. But this is forgetting inertia - the tendency of mass to resist changes in motion. Therefore, although the force on the medicine ball is greater, it takes this larger force to accelerate the ball at the same rate as the basketball.

ome people may find these easy - others not - but it is essential if you want to easily mentally multiply bigger numbers that you first master this.
