Lab 2.1 Exercise 2.1.1 All these elements are necessary because each allows the other to function and do its job. Without Media the signal cannot transmit. Without Interface the computer cannot access the Media. Without the signal the electricity or copper wires cannot transmit information. Without Pattern there would be no established format for the signals. And timing lets the devices know when the pattern starts and ends.

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

by Google engineer Sebastian Thrun‚ director of the Stanford Artificial Intelligence Laboratory and co-inventor of Google Street View. Thrun ’s team at Stanford created the robotic vehicle Stanley which won the 2005 DARPA Grand Challenge and its US$2 million prize from the United States Department of Defense. The team developing the system consisted of 15 engineers working for Google‚ including Chris Urmson‚ Mike Montemerlo‚ and Anthony Levandowski who had worked on the DARPA Grand and Urban Challenges

Transport for London (TfL) aims to keep London moving and to continuously improve the standard of living in the city. The constant growth in population however is making this aim increasingly challenging. It is crucial for Transport for London to continue to improve their service if the city’s success is to continue. (Transport for London‚ 2015) In 2014 TfL identified their main priorities for the foreseeable future‚ safety and reliability‚ maximising capacity from the existing network and meeting

2. Draw and completely label a cell membrane. [pic] 4. List and briefly discuss the 5 components of cellular membranes. 1. Phospholipids layer- 2 layers ‚ polar and non polar ‚ polar facing the extracellular fluid and cytoplasm 2. Transmembrane proteins-integral membrane proteins are proteins that expand the membrane 3. Interior protein network-peripheral proteins are in the interior side of the membrane 4. Cell surface markers are glycolipids‚ carbohydrates/lipid

Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However‚ Active transport requires ATPs which have energy in order for it to move something through the cell membrane. There are different types of transport to suit the sizes of molecules as well. Passive transport includes diffusion‚ osmosis‚ and

Oxygen Exchange and Transport Oxygen exchange or respiration takes place at a respiratory surface; a boundary between the external environment and the interior of the body. Gas exchange is the process by which oxygen and carbon dioxide (the respiratory gases) move in opposite directions across an organism’s respiratory membranes‚ between the air or water of the external environment and the body fluids of the internal environment. Oxygen is needed by cells to extract energy from organic molecules
