The earth doesn’t have an even balance of heat and the reason for this is because the earth is a geoid ‚ the sun’s rays hit directly on the equator(caused by unequal insolation due to three factors: angle of strike‚ atmospheric depletion and surface area.) and then move outwards towards the polar areas. The atmosphere together with the ocean currents work hard to try and even out the imbalance of heat energy by redistributing the air from the equator to the Polar Regions but also from the Earth’s

where the changes occur through genetic drift (Hahn and Bentley 2003). Genetic drift causes these random changes in allele frequencies‚ which result from random fluctuations across generations. Genetic drift happens in ALL populations‚ large and small‚ but affects them to a different degree based on size. Smaller populations tend to be significantly affected by genetic drift‚ while populations of a much larger size might experience some resistance. Although genetic drift usually occurs with one or more

hemophilia is commonly inherited‚ it can also occur due to a spontaneous mutation. Hemophilia A is an X-linked‚ recessive disorder caused by a deficiency of Factor VIII. Hemophilia can be severe‚ moderate‚ or mild. Individuals diagnosed with severe hemophilia A are typically diagnosed early in life‚ prior to age two. This is diagnosed particularly following episodes of bleeding from mouth injuries and bumps on the head. Spontaneous bleeding may occur as well as prolonged bleeding from injuries

Cellular Respiration and Photosynthesis are two processes that occur in a cell. Cellular respiration coverts glucose and oxygen into ATP and its byproducts‚ carbon dioxide and water‚ are what cause photosynthesis to occur which is then converted into glucose and ATP and then release oxygen. Photosynthesis occurs in the chloroplast while cellular respiration occurs in the mitochondria. The glucose for cellular respiration is first split in the cytoplasm during the process glycolysis then the Kreb’s

Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending on the time of application of voltage as shown in Figure 1 and can be classified as follows: Maximum

Pollution‚ we hear it every other day at school‚ college and read about it in newspapers. So what is it? Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution occurs in different forms; air‚ water‚ soil‚ radioactive‚ noise‚ heat/ thermal and light. Every form of pollution has two sources of occurrence; the point and the non-point sources. The point sources are easy to identify‚ monitor and control

to be prepared for failures‚ which may occur in either system and have procedures in place to identify and isolate these failures to prevent an entire network shutdown and implement a solution for their network. Failures can occur at any level of a network and the network admin must be prepared in the wake of these occurrences. There are varying types of centralized systems that businesses can implement. The types of failures that can occur in centralized systems are; network failures

Through association the process of learning is called conditioning. There are two types of conditioning called classical and operant. Classical conditioning occurs when we learn to link two stimuli and anticipate events. It is a type of learning that is majorly influenced by behaviorism. Behaviorism assumes that all learning occurs through interaction with the environment and the environment shapes behavior. Two critical components of classical conditioning are the unconditioned stimulus and

the author or director of a text. Such is the case in Into Thin Air written by Jon Krakaeur and in The Hunger Games directed by Gary Ross Jon Krakauer constructs the text Into Thin Air to establish a sense of inevitability that a disaster will occur on Mt. Everest. He achieves this with the use of foreshadowing. An example from the text is when Krakauer’s teammates are spending time taking photos and he says‚ “nobody suspected that by the end of the day‚ every minute would matter”. This informs
