Voices From the Field Supporting Cell Phone Use in the Classroom Mark Geary ell Phone use is increasing‚ though it is still repressed more than accepted as an educational tool in US high schools. This article discusses how cell phones have been used in a charter school for at-risk students‚ as well as how and why they should be used on a broader basis. Also discussed are some future possibilities for cell phone use based upon the emergence of web 2.0 applications that support

are two types of cell transport mechanisms. These types of transports are passive and active transport. The difference between active and passive is that passive does not require energy and active does require energy. The reason passive does not require energy is because it travels down a concentration gradient. On a concentration gradient molecules naturally move from high to low concentration. In active transport‚ molecules move from low to high concentration. There are three different types of transports

What is it? Sickle cell anemia is a type of blood disorder that can be inherited from parents. This is when red blood cells that are meant to carry oxygen around the body become deformed. Normal red blood cells are round and disc shaped‚ however‚ when they become sickle red blood cells‚ the deform and change shape into a crescent-like shape or sickle shape. The sickle cells have a shorter life-span than a healthy red blood cell and are not replaced as quickly as normal; this leads to a shortage

Eukaryotic Cells Cells are the basic building block of life. Cells can be either Eukaryotic or Prokaryotic cells. Organism can only contain either one but not both of them. Prokaryotic cells are usually much smaller than Eukaryotic and are less complex. Bacteria are made up of one or more prokaryotic cells. Bacteria are made up of one or more prokaryotic cells. While Eukaryotic cell are found inside plant and animal life. Eukaryotic are more advanced and larger. Prokaryotic cell were the first

Are Cell Phones Dangerous? Are cell phones dangerous? Cell phones are dangerous because of many reasons. One reason that cell phones can be dangerous is because if the GPS is on‚ then people can track someone just by the GPS being on. When the GPS is on the predators act like police and know how to track people by the GPS‚ also by photo posts especially when the post is on the photo map. A photo map is used to see where a picture was taken. The next reason why cell phones can be dangerous

fourteen states have banned cell phone usage while driving while the other thirty-six wait for more research. Since cell phone usage has become more common‚ research has been undergoing. Top universities such as Harvard have undergone research and published results proving cell phone distraction to be great danger to those driving and other drivers on the road. Arguments of some distractions that are common are eating‚ reading‚ and putting make up on. Banning cell phone usage would make the roads

Describe the cell cycle. Include in your discussion the role cyclins and CDKs play in controlling this cycle. The cell cycle is a process that cells undergo to grow‚ reproduce‚ and divide to make 2 daughter cells. The cell cycle has different stages including G1‚ S‚ G2‚ and the M phase. Also we have the G0 phase. There are checkpoints that control the transitions between the phases of the cell cycle in which the process is regulated by cyclins and cyclin-dependent kinases (CDKs). G1 is known as

Maximum Cell Size & Diffusion – Ferris Shaw Research Question: How does the surface area to volume ratio affect the diffusion rate in agar cubes? Hypothesis: The rate of diffusion in directly related to the surface area to volume ratio of cells and is responsible for the efficiency of absorbing nutrients‚ oxygen‚ minerals etc. in the cell. This ratio is specific to cells as they require a ratio that isn’t big enough to take too long to receive the nutrients and oxygen or too small to
