Johnny Greavu Student ID: 4391959 PSTL 1112 June 23‚ 2015 Video Response #2: King Corn 1) The US planted 91.6 million acres of corn in 2014. This is down 4% from 2013‚ and the lowest acreage since 2010‚ but still the fifth largest since 1944. About 40% of this was used for ethanol production‚ 36% was fed to livestock‚ 20% was exported‚ and only 4% was eaten by humans (much of this being high-fructose corn syrup). 2) Row crops leave much of the soil (gaps between rows) bare and loose‚ which

Genetic Drift Genetic drift‚ also known as allelic drift‚ is the change in the number of gene variants‚ alleles‚ in a population because of random sampling. The allele frequency in a population is the fraction of the copies of one gene that share a specific form. The alleles in the offspring are a sample of gene variants in its parents. Chance plays a part in whether one survives and carries its genes on‚ or does not. Genetic drift may cause gene variants to disappear completely resulting in reduced

chilly evening after dinner‚ a group of friends decided to go to a haunted corn maze. In the group of friends there was Grace‚ Nick‚ Elizabeth‚ Ella‚ Aiden‚ and Kaylee. They went to the haunted corn maze in Pennsyltucky that started at 11 p.m When the group of friends arrived at the corn maze there were multiple waiting in line‚ they all looked scared with a mix of excitement. Once it was their turn to go through the corn maze they all got goose bumps as if they heard nails on a chalkboard. Once

body of research within health psychology has focused on not only the consequences of obesity but also understanding the causes of obesity‚ both genetic and environmental – this is what this essay will explore.... Genetics There have been several theories put forward by research to best explain the causes obesity and one major potential causes is genetics. Maffeis et al (1998) found that obesity in parents was the strongest predictor of childhood obesity‚ regardless of diet or level of activity

Genetic counseling is defined as consultation and testing by trained experts that enable individuals to learn about their genetic heritage including harmful conditions that they might pass along to any children they may conceive. Genetic counseling and testing‚ like many other advances of modern science‚ has the potential to improve the quality of life for those us who are fortunate enough to live in a country where it is readily available. But just like many other scientific advances‚ it is also

Identical twins share the same genetic code and thus are natural clones. Because identical twins share all of their genes‚ it has been said that it is the environment—rather than genetics—that accounts for any differences between them. Twins can either be monozygotic ("identical")‚ meaning that they develop from one zygote that splits and forms two embryos‚ or dizygotic ("fraternal") meaning that they develop from two single eggs that are fertilized by two separate sperms. In a study design that

One invention on the horizon in genetics that will add yet another technological failure in the health industry is genetic engineering. Genetic engineering has been known to be used on plants and food‚ but what about babies? Yes‚ babies are beginning to be genetically modified to look however the parents want them to.

viruses or environment factors. When a mutation occurs in ones genetic structure‚ there is often a push to find out what went wrong and if it was a onetime occurrence or a genetic abnormality that no one in the family knew about until the recent discovery. This genetic abnormality occurs when there is a dominant gene which comes from a parent. This dominant gene attaches itself to a recessive gene and sparks a change in the genetic sequence of the offspring. This is most relevant as I was observing

WHAT IS HIGH FRUCTOSE CORN SYRUP? * High fructose corn syrup (HFCS) is a calorie-providing sweetener used to sweeten foods and beverages‚ particularly processed and store-bought foods. It is made by an enzymatic process from glucose syrup that is derived from corn. A relatively new food ingredient‚ it was first produced in Japan in the late 1960s‚ then entered the American food supply system in the early 1970s. HFCS is a desirable food ingredient for food manufacturers because it is equally
