Speed Mastery Quest Pt.2 (REGRADE)

Question: Which section of the graph represents the highest speed?

 Wrong Answer: The last section, where the time is 185 seconds to 200 seconds.

 Correct Answer: The first point of data in which the time is 20 seconds and the distance is 15 meters.

 Why: The reason the first point was correct is because you have to find the speed of each point, meaning you divide the distance by the time. If you do this you will get that Point A- 0.75, Point B- 0.5, Point C- 0.61, Point D- 0.53, Point E- 0.48,  and Point F- 0.5. Through this, you can see that the first point, Point A, clearly has the fastest speed.I got this problem wrong because I misinterpreted it. I thought it was asking for the greatest change in speed, but using the distance over time formula I was able to resolve this conflict.

Cladograms, cladograms, cladograms 10/22/17

Image: Pierre Kleinhouse Summary:  When we think of evolution we see monkeys magically turning into humans, but what is missing from that picture is the portion below it that makes it a cladogram. What is a cladogram? A cladogram is a diagram that shows the common characteristics of certain animals, as well as how closely related they may be. The top of the cladogram includes the organisms name and sometimes a picture. On the side of the cladogram, you will usually see different characteristics. Since a cladogram is drawn at a downward angle, the characteristic applies to everything above that point on the diagram. As you go up the cladogram, the animal at the top has all the characteristics listed throughout the cladogram. Along with this, the points in which two animals meet is not when they evolved from one another, but their common ancestor. Lastly, the diagonal line of a cladogram represents time.

Stress On the Brain 05/13/18

Image:  YouTube Summary: Chronic stress, or long-lasting stress, can make you feel isolated, overwhelmed and make you have sudden changes in mood. An example of chronic stress is getting overworked on a regular basis. When you are overworked and you are stressed about what you have to complete the size, function, and structure of your brain are affected. After a natural disaster, people are overcome with feeling shock, but that eventually morphs into guilt, depression, and anxiety. People who are suffering from the loss of a loved one, can feel helpless and powerless. The traumatic effects of natural disasters, no matter the natural disaster, show that victims suffer from PTSD and guilt of surviving. This is because, although not all disasters are the same, the survivors all endured a catastrophic, life-changing event, in which they experienced loss. However, the traumatic effects of a natural disaster are different on the brain, depending on the disaster, because survivors exp
