FAQ
How does the brain regulate the functions of the body?
To ensure that they work together, messages are sent by the brain to other organs. Everything that happens within your body is controlled by the brain. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Action potentials on Axons are an electrical signal that neurons send to each other. Every neuron has an outer cell membrane that surrounds its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. The neuron fires when there is ion movement.
Neurotransmitters, which are chemicals that release neurotransmitters when a neuron fires up, can be found in the space between the neurons and the next one. Neurotransmitters can bind to receptors at the second neuron. They open ions channels, allowing ions to move in and outside of the channel. This causes the second neuron to fire too.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. An impulse travels along a synaptic link between the two neuron. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.
The nervous system relies on neurotransmitters for communication. They are also responsible for coordinating activity between various parts of the brain.
Have you ever wondered how much trash is produced worldwide each day?
According to the United Nations the average person creates more than 2.5 lbs of waste daily. That adds up over 25 billion kilos of garbage every year.
Most of this rubbish ends up in landfills or incinerators. But, what happens when those dumpsters fill up? Most of that trash is shipped out of the country. It then gets dumped in foreign countries, polluting their ecosystems. However, now we know where all that trash goes. Mike Sexton is his full name. He runs Waste Watchers, a company that monitors the movements of trucks carrying trash all across North America. He then gives us a report on what happens next.
Sexton claims he is very satisfied with his job. CNN's Sexton said, "We have a lot to enjoy." "We see big rigs coming through town and we'll follow them. "Sexton began following truck drivers almost 20 years ago.
"I just fell in love with it," he said.
Sexton loved the story about the driver who pulled over at an abandoned gas station close to Los Angeles. Sexton said that the man was searching for a place to store his stuff. "He drove down the road to see this building. So he backed up and went inside. "There were two huge roll-off containers there filled with stuff. The man removed everything from the truck and started to load it again. "Then he looked at the place and decided to unload everything. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was a complete mess. But it had been cleaned out before he came along. There wasn't any trash anywhere."
This begs the question: Why? It's because this area used to be a recycle center. People would drive from all over the country to recycle their trash. Sexton said that people would bring their household items to the building and then leave empty containers behind.
This can happen hundreds of times a week. This can happen hundreds of times a week.Eventually, the truck becomes so overloaded with junk that it stops running. The owner eventually decides to dump the truck.
Trash, however, isn't the only problem facing our planet.As you may have noticed, things are getting worse.According to experts, pollution levels have risen dramatically in recent years.More than half of all water bodies on Earth are polluted.Pollution from industrial chemicals has increased by more than 30 percent since 1980.Even the air we breathe is becoming increasingly toxic.A study by the World Health Organization found that the average person inhales around 100 million particles daily.
The majority of these particles are made of small pieces of plastic. Others end up in rivers, oceans or the stomachss of fish.
Experts warn that if there is no change, the world could soon be facing a food shortage. Experts warn that "if we keep going the way we are, we're not going make it," although scientists agree that the world is heading toward disaster. Most people, however, don't seem to be concerned.
Is there an Hollywood blacklist?
There is a Hollywood blacklist.
But, the list has not been made public. We don't know the names. But, here's why it matters.
The reason behind the secrecy was that blacklisted directors and actors wouldn't be able find work. Thus, they would leave the industry and studios will lose money. It would mean they would reduce their expenditure on movies. This would result in fewer opportunities available for blacklisted filmmakers. This could lead to them going bankrupt.
This could mean more victims.
In short, when someone tries to make an oscar winning movie, they might be asked to sign a contract saying they won't speak publicly against their employers. Any director or producer who would like to be nominated for an award is subject to the same rules.
That's why you hear stories about how producers pressure directors to remove scenes from their films. Or directors threaten to walk out of projects that don’t match their vision.
This is why Hollywood keeps a blacklist. Negative comments about your employer will most likely lead to you being unemployed. This is bad news for anyone.
Many people have been wrongly accused. They have had to fight for their freedom.
We need to stop this kind of thing before it starts happening again. Everybody should be able to freely express themselves.
Therefore, it is necessary to eliminate the Hollywood blacklist.
