Phytopharmaceuticals are pharmaceutical compounds that are found in plants. They can be naturally occurring or a result of biotechnology. Recently, scientists created genetically modified (GM) corn that produces the antibiotic penicillin. The seeds of this GM corn contain a large amount of the antibiotic penicillin, making the cost of producing the penicillin much cheaper and making the method of delivering it to patients in need much easier. Given the benefits of this GM corn, which of the following may be a concern regarding its production?
A.The GM corn may develop infections from bacteria that are sensitive to the antibiotic.
B.The GM corn might pass resistant genes to other organisms, like birds, that may eat the seeds.
C.Because corn uses the wind for pollination, people allergic to penicillin may be at risk for exposure to the antibiotic in the air.
D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Answer:
The answer is D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Explanation:
The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
What are genetically modified crops?Through the use of laboratory procedures, genetic modification (GM) technology enables the transfer of genes for particular traits between species.
In the middle of the 1990s, GM crops were first made available in the U.S. The majority of GM crops being farmed in the U.S. have been modified to be herbicide or insect resistant. The three GM crops with the highest acreages are corn, soybeans, and cotton.
The technology has the potential to be used in the future to improve nutrition, stress tolerance, disease resistance, biofuel efficiency, and the cleanup of polluted places.
The U.S. Department of Agriculture (USDA), the Environmental Protection Agency (EPA), and the Food and Drug Administration (FDA), each with the ability to regulate particular parts of the crops, are in charge of regulating GM crops at the federal level.
Therefore, The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.

How does each Fossil Fuel (coal, oil, & natural gas) affect the environment?
Answer:
When we burn oil, coal, and gas, we don't just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.

this phenomenon, which provides evidence for the big bang theory, is called what?
Answer:
Doppler Red-Shift Evidence
Explanation:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
