What are frankenfoods? Are Genetically Modefied foods safe?
barxatty [35]

Opponents of GMOs have been unceasing in their campaign to vilify genetically modified foods by describing them as “Frankenfoods,” thus implying they are not natural and are potentially harmful.

“The practice of introducing new DNA and chemicals to seeds or animals (Aqua Advantage has developed a GMO fish) is similar to how Mary Shelly’s Frankenstein created his monster–—through piecing together lots of different organisms,” wrote the Organic Authority on its website—a common allusion in the anti-GMO world. “We all know what happened when the monster turned on Frankenstein, and many critics of genetic engineering have likened the inevitable backlash of GMO technology to the destruction and murderous rampage of Frankenstein’s monster.”

Many anti-GMO articles that warn of the dangers GM crops are often accompanied by an image of a tomato fruit or vegetable with syringes sticking out of them. Very often it is a fruit or vegetable for which there is no current GM equivalent such as a tomato. This depiction is used to reinforce the notion that GM foods are created in laboratories and not by nature and therefore are dangerous to consume.

With the constant barrage of scare-based imagery, it is not surprising that there is widespread public suspicion that GMOs are dangerous to human health. But there is little controversy surrounding GMOs within the scientific community with 88 percent of the members of the American Association for the Advancement of Science believing GMOs are “generally safe.” The safety of GMOs were once again reinforced by the May 2016 report by the U.S. National Academy of Sciences, Engineering and Medicine, which concluded, there was “reasonable evidence that animals were not harmed by eating food derived from genetically engineered crops”, and epidemiological data indicated there was no increase in cancer or other health related problems associated with these crops entering our food supply.

David Zilberman, a professor of agriculture and resource economics at the University of California, Berkley, has noted that Frankenfood was “a terrible word, a stigmatization word, one that’s used to scare people… People are afraid of GMOs for little or no reason. GM is simply a tool. Because it allows us to modify plants with far greater precision and control then before, it will be very valuable.”

The reality is that the vast bulk of the foods we consume whether organic or conventionally grown have had their genetics altered in the field or in a laboratory via a process of selective breeding or advanced biotechnology techniques, and all such foods are safe to eat. The altering of genes in plants is even known to occur naturally as highlighted by the sweet potato.

<h3>What causes infectious diseases?</h3>

Coming into contact with a person or an animal who has the virus is one of the most straightforward ways to obtain the most contagious or infectious diseases. Direct contact, such as person-to-person contact, can transfer contagious diseases. Direct transmission of bacteria, viruses, or other germs from one person to another is the primary method by which contagious diseases are typically disseminated. If someone who is unaffected touches, kisses, coughs, sneezes, or has the virus or bacterium on them, this could happen. Additionally, these pathogens can disperse through sexual contact and the exchange of bodily fluids. The person who spreads the infection may only be a carrier and not exhibit any signs of the illness.

Describe the chemical make up and type of bonding found in water molecules?
andre [41]
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
