What’s the life of a cell like? In this episode of Crash Course Biology, we’ll follow a cell’s life cycle, from its beginning as a shiny new cell all the way to division via mitosis. We’ll learn how our cells control this process, and...

Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad....

Look at this beautiful vulture pavilion! Gwendolyn the turkey vulture is all moved in and we're excited to see her enjoy her new space and all that sunshine!

Howcast - Learn how to say "son" and "daughter" in Mandarin Chinese in this online language lesson from Howcast.

This lesson will be the onset of creating a set of banners. We will start work on creating the first one. These can be useful to use in a dungeon or castle to add character to it through different house or lineage colors and decals.

The cycle of events involved in normal cell growth and division, in multicellular organisms.

Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...

We know that your body produces more cells through mitosis. But where did your very first cell come from? It can't have been mitosis, because mitosis needs a cell to start with. As it turns out, meiosis and subsequent fertilization are...

👉 Learn about the characteristics of a function. Given a function, we can determine the characteristics of the function's graph. We can determine the end behavior of the graph of the function (rises or falls left and rises or falls...

We know that we are made of cells. But we start out as just one tiny little cell in the womb. How does that become enough cells to look like a baby? And how does that baby get enough cells to become an adult? The answer is mitosis! This...

You'd think that air that was the same temperature as your body would feel neutral, but if you've ever been outside when it's 37 degrees Celsius out... you know that's not the case! Hosted by: Stefan Chin

Sometimes, major injury causes blood loss that results in improper clotting, or coagulopathy. Some researchers think a compound used in perfume to create jasmine fragrances could help save these patients.
