Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

Meiosis is the type of nuclear division that occurs to form four genetically different gametes. This produces genetically different offspring which all differ in traits‚ the reason this occurs is because of the way that the chromosomes are handled to make gametes. The general gist of meiosis is that a homologous pair is split twice to make four separate cells that have the haploid number of chromosomes meaning when they fuse with other gametes they form a zygote with the diploid number of chromosomes

Mitosis is a way to help your body replace worn out cells. Mitosis has five phases‚ six if you include Cytokinesis. The phases of Mitosis are Interphase‚ Prophase‚ Metaphase‚ Anaphase‚ and Telophase. These phases all work together in order to help recover worn out muscles ‚ skin and other types of cells. Mitosis is when one cell divides into two daughter cells. Mitosis is very useful for organisms. Without Mitosis organisms would not be able to repair cuts and could result in death. It is also

AP BIOLOGY- Mitosis and Meiosis Cell Division Lab Part 1-MITOSIS summary: In this experiment first the stages of an onion cell undergoing mitosis are going to be observed and every stage is going to be detected and drawn on paper. A brief description to what is going on should be attached to the pictures. This is important to understand the basics of cell division which is necessary growth‚repair

You have probably met and known many different people in your life. Most of them may simply be acquaintances‚ while others you might consider friends. Of these‚ there may be only a few that you would consider close friends. Then‚ perhaps‚ there is that one person who is as close to you as a brother or sister or perhaps‚ as the Bible says‚ “is a friend that sticks closer than a brother” (Prov. 18:24)‚ someone in whom you can confide and trust‚ and with whom you can share your hopes and dreams.

Long-term global warming trend sustained in 2013 1 January 21‚ 2014 Steve Cole‚ NASA Headquarters Leslie McCarthy‚ NASA Goddard Institute for Space Studies NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880‚ continuing a long-term trend of rising global temperatures. With the exception of 1998‚ the 10 warmest years in the 134-year record have all occurred since 2000‚ with 2010 and 2005 ranking as the warmest years on record. Global temperatures have

Title: Investigation in microtubule dynamic instability Introduction Microtubules are important for maintaining cell structure‚ intracellular transport‚ formation of mitotic spindle‚ as well as other cellular processes. Investigation of dynamics of microtubule assembly and disassembly allow us to understand the malfunction of mitotic spindle formation or other cellular processes. This experiment is divided into two parts; we are going to find out the critical parameters for achieving greatest average
