Hey I'm Cassie. I love riding horses and hanging out with my friends.

My favorite topic so far in biology has been beginning to learn about cells. It is really interesting because you always hear that cells make up every living thing but I didn't know much about cells. It is good to learn about a common thing that is very relatable. It was also very fun to do the lab where we made model cells and measured how long in took for vinegar to diffuse into them. Ours both took more than 25 minutes.

A centriole is a ring of 9 groups of microtubes, with 3 microtubes in each group. The 2 centrioles are perpendicular to each other and they are part of the centrosome.

During animal cell division, the centrosome divides and the centrioles make new copies. This turns into two centrosomes, each with its own pair of centrioles. The two centrosomes move to opposite ends of the nucleus. They
generate the cell's cytoskeleton. They then produce microtubes in star-shaped clusters known as asters. The asters move to opposing poles of the cells and the microtubes form a spindle-shaped formation that spans the cell with the help of the centrioles. These spindle fibers act as guides for the chromosomes as they later divide.link

When people drink more than 315 milligrams of caffeine, they are more likely to hallucinate than those who drink one. This is equivalent to 3 cups of brewed coffee, seven cups of instant coffee, six cups of strong tea, nine sodas, or four Red Bulls. People with that high of a caffeine intake have a three-times higher risk of hearing voices and seeing things that are not there. It can also cause nervousness, irritability, anxiety, muscle twitching, insomnia, headaches and heart issues.
Caffeine is a stimulant that causes less drowsiness and more alertness. 90% of Americans consume some kind of caffeine every day. It is the world's most widely used drug.
Caffeine use can lead to a condition called caffeine intoxication. Symptoms can include nervousness, irritability, anxiety, muscle twitching, insomnia, headaches, and heart palpitations. This is not commonly seen when daily caffeine intake is less than 250mg.
The Economic and Social Research Council and the Medical Research Council did a study on 200 college students in the United Kingdom. The students were asked about their usual caffeine intake, their level of stress, and their tendency to experience hallucinations. Some of the people reported seeing things that were not there, hearing voices, and sensing dead people. The researchers believe that caffeine intensifies stress. The body releases a hormone called cortisol when under stress. More of this hormone is released in response to stress when people have recently had caffeine. This extra cortisol may link caffeine intake to an increased hallucinations, said study leader Simon Jones, a graduate student at Durham's Psychology Department. Caffeine can be very dangerous if too much is consumed, and especially because so many people depend on and drink lots of caffeine.

What are some other side effects of too much caffeine? Are there any other things that can cause hallucinations? Are these hallucinations actually real?
Take the poll! I made related to this post.
Look at the comic I made related to this post.
Cassie this post is really good your sources are credible and you have questions and you put creativity in it.-Teddy
