How is hair grown? give me a really really really detailed answer​
Rainbow [258]

Hair grows out of little pockets in your skin, called follicles. Here's how it happens:

Your hair begins growing from a root in the bottom of the follicle. The root is made up of cells of protein.

Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow.

The hair gets pushed up through the skin as it grows, passing an oil gland along the way. The oil gland adds oil to the hair and keeps it shiny and soft. It can make it greasy, too. That's why you need to wash your hair.

The hair dies by the time it is long enough to poke out through the skin. Yes, hair is dead. That's why it doesn't hurt to get a haircut.

Hair on the rest of your body goes through this same process, but the whole cycle only lasts for a month or so. That's why body hair does not grow very long in length like the hair on your head does.

Here are some facts about follicles and your hair:

You are born with all of the follicles you will ever have — about 5 million.

You have about 100,000 follicles on your scalp, which is the skin on your head.

Hair grows very fast and male hair grows faster than female hair. The only part of your body that grows faster is bone marrow, the soft stuff inside your bones. The hair on your head grows about 6 inches a year. So, even though it's one of the fastest-growing things on your body, it takes a while to grow it really long.

Some follicles stop growing hair as you get older. This happens more in some people than in others. That's why some people get thinner hair when they get older, or go bald.

What was the Laurentia and what was it composed of? What happened to it?
Nataly [62]
Laurentia<span> (</span>North American Craton<span>) is a large continental </span>craton<span> that forms the ancient geological core of the </span>North American<span> continent. Many times in its past, Laurentia has been a separate </span>continent<span> as it is now in the form of North America, although originally it also included the cratonic areas of </span>Greenland<span> and also the northwestern part of </span>Scotland, known as theHebridean Terrane<span>. During other times in its past, Laurentia has been part of larger continents and </span>supercontinents<span> and itself consists of many smaller </span>terranes<span> assembled on a network of Early </span>Proterozoic orogenic<span> belts. Small </span>microcontinents<span> and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable </span>Precambriancraton seen today.
