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.

wariber [46]

Answer:

Whole wheat pasta tossed in olive oil with veggies and tofu

Explanation:

Triglycerides and cholesterol are lipids and their higher concentration in the body leads to cardiovascular diseases. Food items rich in lipids such as potatoes, chocolates, cheese, French fries, etc. should be avoided by a person having higher triglycerides and cholesterol levels to prevent the development of any heart disease. Similarly, whole grains rich in fibers that remove the fats from the body, vegetables rich in natural fibers, vitamins, and minerals and almost devoid of fats, protein-rich tofu should be preferred to maintain good health.

What happens in your body to cause you to get a fever?
andriy [413]

The presence of a fever is usually related to stimulation of the body's immune response. Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive. Infectious agents are not the only causes of fever, however. Amphetamine abuse and alcohol withdrawal can both elicit high temperatures, for example. And environmental fevers--such as those associated with heat stroke and related illnesses--can also occur.

The hypothalamus, which sits at the base of the brain, acts as the body's thermostat. It is triggered by floating biochemical substances called pyrogens, which flow from sites where the immune system has identified potential trouble to the hypothalamus via the bloodstream. Some pyrogens are produced by body tissue; many pathogens also produce pyrogens. When the hypothalamus detects them, it tells the body to generate and retain more heat, thus producing a fever. Children typically get higher and quicker fevers, reflecting the effects of the pyrogens upon an inexperienced immune system.

From which of the following does the right atrium receive blood?
olga2289 [7]

The right atrium receives blood returning from others parts of the body through the superior vena cava and the inferior vena cava.  

Explanation:

The pathway of circulation begins in the right atrium which receives the carbon dioxide-rich deoxygenated blood returning through the systemic circulation.  

The deoxygenated blood from regions superior to the heart, i.e., the head, neck, shoulder areas are collected through the superior vena cava and that from the parts inferior or lower to the heart like visceral organs, extremities, trunk, hip etc are brought through the inferior vena cava.

Both these venous systems (superior and inferior) fill the right atrium.

The right atrium then pumps the deoxygenated blood to the right ventricle via the tricuspid valve.

The right atrium is filled with blood during diastole.
