Thunderstorms Kyle Cowan Known as the electric storm‚ thunderstorms occur all the time. When a thunderstorm starts to occur‚ the air starts to cool as it rises. Cumulus clouds start to form as water vapor starts to condense. As condensation occurs‚ heat (latent heat/energy)‚ starts to release from the atmosphere and assists the thunderstorm in becoming created and grow. Soon as the thunderstorm is formed‚ condensation high in the cloud (now in the form of water droplets or ice) starts

November 10‚ 2011 Mitosis /Meiosis Mitosis occurs all the time in all body cells. This occurs to produce new cells and replace old and dead cells. We produce new blood cells‚ bone cells‚ skin cells...the list can go on and on. Mitosis in a nutshell is the process of splitting the nucleus and it occurs hand in hand with the rest of the cell cycle and cytokenesis. Meiosis‚ on the other hand‚ is a process of taking a

Genetic disorders are a topic in biology that can not be avoided. The fact is that genetic disorders can happen in humans‚ plants or animal. No one and nothing is safe from a genetic disorder. A genetic disorder can appear in the first years off life‚ or can appear much later in life when least expected. A basic principal of biology states that the behavior of chromosomes during the meiosis process can account for genetic inheritance patterns. There are many reasons for genetic disorders. To start

often while staying blind to what is really in front of us. Most often occurs at the idea phase. • Design-Free Design: Designing policies for passage through the legislature‚ not for implementation. Most often occurs at the design phase. • The Stargate Trap: The risk that the idea never makes it through the legislature or it becomes so distorted on the way through that it will never achieve the intended results. Occurs only at the Stargate phase and is particularly challenging in the public

rocks into smaller fragments brought about by physical (mechanical) forces. Works through 4 processes: alternate expansion and contraction‚ frost action‚ pressure release and salt crystal growth. Alternate expansion and contraction- this process occurs in areas such as desserts. The rock expands during the day because of the heat and contracts at night when temperatures drop below freezing point (0 degrees). Constant expansion and contraction of the rock causes cracks within the rock.

aerobic harvesting of chemical energy from organic fuel molecules. The three stages are; glycolysis‚ the citric acid cycle‚ and the electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? The word itself means “splitting sugar”. That is what happens during glycolysis‚ a six-carbon glucose molecule is broken in half‚ forming two three-carbon molecules it requires two ATP molecules per glucose. The three-carbon molecules then

lost‚ movement can be affected and paralysis can occur. In many individuals with polio‚ they body is able to sprout new nerve terminals as means of compensation‚ allowing for movement recovery. However‚ it is thought that after years of use‚ these new motor neurons become overstressed and begin to deteriorate. This leads to loss of muscle strength seen in those with post-polio. Restoration may occur again‚ but eventually permanent weakness occurs (Post-polio syndrome (PPS)‚

Insight learning • Wolfgang Kohler did studies with chimpanzees • Insight learning occurs when one suddenly realizes how to solve a problem • Chimps using boxes to reach banana What Is Learning? Learning is a relatively permanent change in behavior due to experience. Learning resulting from conditioning depends on reinforcement. Reinforcement increases the probability that a particular response will occur. • Classical (or respondent) conditioning and Operant (or instrumental) conditioning
