having 55 minute class periods allows me to count down the minutes ‘till I get out of the darn class. Imagine having 90 minute class periods. I would fall asleep and not learn anything. The whole point of school is to learn. Schools should not have block schedules because it becomes harder to focus for long droning lessons‚ absences cause significant damage to grades when students can not catch back up‚ and teaching becomes segmented and hard to follow when teachers see their students so little every

The Pratt Truss was designed by Thomas and Caleb Pratt in 1844. It became popular for railway bridges because it made good use of iron. The Pratt has many variations‚ most with their own unique name. For instance‚ the Baltimore‚ Pennsylvania‚ and the Parker are all based off the Pratt. Pratt Truss How the forces are spread out Here are two diagrams showing how the forces are spread out when the Pratt Truss is under a load. The first shows the load being applied across the entire top

roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

In this paper I will describe the head to toe mechanics of what a normal‚ athletic volleyball block consists of. This movement may seem simple when watching a player perform it on the court; however it is a very complex muscular movement. There will be three phases I will explain in this movement. First the athletic position or “start phase”‚ next the jumping motion or “active phase” and finally will be the landing known as the “ending phase”. I will be describing every motion‚ as well as what plane

4f and 5f block elements 1. Name the 4f – block elements and give their electronic configuration. Why are Sc‚ Y‚ and La included in the list of lanthanide elements 2. What is lanthanide contraction? How does it affect the chemical behavior of Zr/Hf‚ Hb/Ta‚ Mo/W ? 3. Contrast the electronic spectra of the lanthanide and transition metal ions. Why do the lanthanide ions give rise to very sharp bands in their electronic spectra and why are the magnetic properties of their complexes little affected by
