The least likely reason that pigs have been chosen as donors for humans in the process of xenotransplantation is the same DNA as humans. Xenotransplantation is the process of transplanting organs from one species to another.

It can lead to more birth defects. Genetic engineering may create stronger, healthier plants and animals. It may also create more plants and animals with mutations or birth defects that can harm the species.

Correspondingly, which is a disadvantage of using DNA technology Brainly? The correct answer is that the disadvantage of gene transfer is that it targets the non target species. The disadvantage of using DNA technology is that sometime the gene transfer to the non target species.

Which best explains why DNA technology is important for disease prevention? A. It can help detect if a person is prone to certain diseases. The restriction enzymes cut the isolated DNA into fragments.

Which is a disadvantage of using DNA technology? There are economic concerns surrounding the products that have been genetically engineered for particular traits, including pharmaceuticals, crops, and enzymes that are used in industry and manufacturing processes.

Which is a potential negative consequence of using genetically engineered medicine? Gene markers that are resistant to antibiotics are used, providing the possibility for humans to have increased antibiotic resistance. Products that are used to genetically engineer medicine are poisonous.

“Everything matches up perfectly. The pig is genetically very close to humans.” Schook explained that when we look at a pig or a human, we can see the difference instantly. “But, in the biological sense, animals aren’t that much different from one another — at least not as different as they appear,” he said.

The correct answer is cancer. Cancer is the consequence that scientists are concerned that is could possibly result from the use of genetically engineered growth hormones in dairy products. Cancer involves abnormal cell growth that is potentially be spreading in the body.

What occurs at step 4 in the diagram? The foreign DNA is placed in a mechanical vector for cloning. The foreign DNA is placed in a biological vector for cloning. The foreign DNA is inserted into the host cell genome.

Biotechnology (Mayfield)

Our Mother Earth is currently facing a lot of environmental concerns. The environmental problems like global warming, acid rain, air pollution, urban sprawl, waste disposal, ozone layer depletion, water pollution, climate change and many more affect every human, animal, and nation on this planet.

Various Human Activities That Affect an Ecosystem

• Agriculture.
• Deforestation.
• Overpopulation & Overconsumption.
• Plastic Production.
• Emission of Carbon Dioxide and Other Greenhouse Gases.
• Destruction of the Reefs.
• Production of Black Carbon.
• Draining Streams/Rivers and Destruction of Critical Freshwater Aquifer Recharge Areas (Water Pollution)

destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.

protection and development of new endangered habitats , often by making National Parks. replanting hedgerows because there is higher biodiversity in them than the fields they surround. reducing deforestation and the release of greenhouse gases. recycling rather than dumping waste in landfill sites.

Technology can be used to restore biodiversity as well as to destroy it, either intentional (e.g. resource extraction) or unintentional, through its unmanaged effects (e.g. some types of genetic engineering). Thus awareness and responsibility are key when designing and utilizing any type of technology.

Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.

Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. Provide for nutrient storage and recycling.

Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food.

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
