Science in the News 2

       The article is about "Wolves Howl Because They Care: Social Relationship Can Explain Variation in Vocal Production." by Cell Press. 
http://www.sciencedaily.com/releases/2013/08/130822122804.htm

        Animal vocal production may be seen as voluntary. Wolfs can use their vocalizations in a flexible way. Scientist  know little of  why animals do this sounds. On the science center human walk with wolves. They record each of their reaction wolfs have when they take them for a walk.This observations shows that wolves howl more  when another wolf in which has a relationship with the others wolves or is in a high rank leaves the wolf pack. Scientist think that they howl so that they can reunite with the other wolves or to stay in contact with them.

  In my opinion this may be true because animals for example wolfs howl to communicate with each their. So then they can be howling to communicate with other wolfs near the area to form a group to hunt or to just see were are the other wolf packs. The author of this article did gave much of evidence in which it makes it more easier to believe that wolfs are howling for
communication or to find other wolf packs. 

classroom safety

         


         Safety is very important thing in chemistry class because for example using goggles is very important because if there s a chemical that you are working with and it gets in your eye than you can finish being blind. Always use the appropriate equipment in a lab, no horseplay and always wait fr the teachers instructions are basically the most important rules in the class that are needed to follow. Science is a very interesting topic to learn about mostly because you learn things that are useful to know about. In the class of chemistry I like how the teacher explains very well and with energy. In this year I am going to study and pay attention to make it a successful year.

     This article is about "New Evidence for warm-blooded dinosaurs" by the University of Adelaide. http://www.sciencedaily.com/releases/2013/07/130717194948.htm

      In this article they compare the dinosaurs with the crocodiles ability in which the crocodile can be basking in the sun until its temperature reaches 30 Celsius  below its normal temperature. The theory that professor Roger Seymour has is that in large dinosaurs can enjoy a warm body temperature without the need t generate the heat in their own cells through burning food energy. For example professor Seymour said that crocodile has less muscular strength than a dinosaur in which case it tells that dinosaurs have the power for excessive in which crocodiles lack in.

      My opinion in this article is that i may have been possible that dinosaurs were warm-blooded. For example there are many mammals that are warm-blooded animals and dinosaurs were mammals and maybe there could have been a dinosaur that was warm-blooded.I agree with the author but he doesn't gives too much evidence and with the little evidence he uses as support it is very hard to believe his theory he invented.
