Answer 12

true

Question 13

Agricultural plants are most frequently genetically modified to

Answer 13

improve the yield, quality and cost of the foods.

Question 14

Some benefits of plant genetic engineering in agriculture;

Answer 14

increased crop yields,
reduced costs for food ordrug production,
reduced need for pesticides,
enhanced nutrient composition and food quality,
resistance to pests anddisease, greater food security, and medical benefits to the world’s growingpopulation.
mature faster and tolerate aluminum, boron, salt, drought, frost, and other environmental stressors, allowing plants to grow in conditions where they might not otherwise flourish

Question 15

More than 95% of animals used for meat and dairy in the United States eat GMO crops.

Answer 15

true

Question 16

There are benefits for both farmers and consumers. For example

Answer 16

higher yields and longer shelf life may lead to lower prices for consumers, and
pest-resistant crops means that farmers don’t need to buy and use as manypesticidesto grow quality crops.
GMO crops can thus be kinder to the environment than conventionally grown crops.

Question 16

The firstgeneticallyengineered plants to be produced for human consumption were introduced in the mid-1990s. Today, approximately 90 percent of the corn, soybeans, and sugar beets on the market are GMOs.

Answer 16

true

Question 17

Geneticallyengineered crops;

Answer 17

produce higher yields,
have a longer shelf life,
are resistant to diseases and pests,
and even taste better.

Question 18

A number of animals have also been genetically engineered to

Answer 18

increase yield and
decrease susceptibility to disease.

Question 19

Some GMO animals, however, are produced for human consumption. For example;

Answer 19

Salmon has been genetically engineered to grow larger and mature faster, and the U.S. FDA has stated that these fish are safe to eat.

Question 19

Most animals that are GMOs are produced for use in laboratory research. These animals are used as “models” to study the function of specific genes and, typically, how the genes relate to health and disease.

Answer 19

Cattles have been enhanced to exhibit resistance to mad cow disease.

Question 20

The process of genetic engineering

Answer 20

1 identify a trait on interest
2 isolate the genetic trait of interest
3 inset the desired trait to new genome
4 growing gmo
For example, insect resistance gene was taken from Bacillus thuringiensis(Bt) which is a naturally occurring bacterium in the soil that produces proteins specifically active against certain insects.

Question 21

Bacillus thuringiensis(Bt

Answer 21

Bacillus thuringiensis(Bt) is a naturally occurring bacterium in the soil that produces proteins specifically active against certain insects. Some crops such as corn, cotton, and soybeans have been genetically engineered to express theBtgenes that act as insecticides.Btcorn is designed to control corn pests such as the European corn borer, corn earworm, and southwestern corn borer, andBtcotton effectively controls cotton pests such as the tobacco budworm, cotton bollworm, and pink bollworm [7]. The use ofBtcrops has led to a reduction in conventional synthetic insecticide use

Question 22

The threats posed by climate change

Answer 22

floods,
droughts,
intense storms
and hotter temperatures.

Question 23

Drought resistant

Answer 23

Maize needs plenty of water to thrive. But many farmers in drier regions now plant drought-tolerant maize.

Similarly with using drought resistance crops;

Conserve soil and water
Use other nonsitable areas for farming
Improve yield in harsh environment (deserts, mountains, cold regions)

Question 24

Chinese and American laboratories dominate the GMO sector.

Answer 24

true

Question 25

Genetically engineered crops help support conservation biological control

Answer 25

More food on less land
Reduced CO2 emission (less time on tractor)
Less food waste (increase shelf life, less disease)
Less contamination of soil with pesticide/insecticide

Question 26

Protecting Biodiversity

Answer 26

Genetically engineered (GE) crops producing insecticidal proteins fromBacillus thuringiensis(Bt) (mainly Cry proteins) have become a major control tactic for a number of key lepidopteran and coleopteran pests, mainly in maize, cotton, and soybean.

the vast majority of studies demonstrates that the insecticidal proteins deployed today cause no unintended adverse effects to natural enemies.

These insect-resistant crops incorporate one or more proteins from a common soilbacterium,bacillus thuringiensis (Bt),that kill target insects like the corn borer, but not other non-target insects, mammals, or humans.
Furthermore, when Bt crops replace synthetic chemical insecticides for target pest control, this creates an environment supportive of the conservation of natural enemies.

Question 27

The Effects of GMOs on Beneficial In

Answer 27

Pollinators, such as bees, are very important not only foragriculture but also for biodiversity. Bees collect pollen and nectar to keep their hives alive, as well aspollinate plants. Pollination is a necessary part of some plants’ fertilization processesbecause it allows for the development of fruits and seeds.

EPA checks modified plants and their impact on bees

Many have claimed that certain GMO crops harm pollinators, however, there is currently no evidence that GMOs have caused adecline in beesor other pollinators. Extensive field experience with commercial herbicide tolerant orinsect resistant GM cropshas shownno deleterious effects

neonics” – could be negatively impacting honey bee health..Neonics are the most widely used class of insecticides and were adopted to replace another class of pesticide, organophosphates.

Question 28

Golden Rice Project

Answer 28

Golden rice is genetically modified to produce beta-carotene, which is not normally present in rice. Beta-carotene is converted into vitamin A when metabolized by the human body. We need vitamin A for healthier skin, immune systems, and vision.

The World Health Organization estimates that about 250 million preschool children are affected by VAD. Approximately 250,000 to 500,000 of these children become blind every year
Vitamin A supplementation could prevent 2.7 million childhood deaths.

Question 29

The Opposition to Golden Rice

Answer 29

Golden Rice will be cultivated in countries such as Bangladesh and the Philippines, where there is a high risk of VAD and where rice consumption is high. However, Golden Rice is not yet ready for farmers to grow or for people to eat;
Golden Rice has low and variable levels of beta-carotene
Golden Rice has not been adequately tested for bioavailability
We do not know whether Golden Rice improves the vitamin A status of people suffering from VAD. Vitamin A can only be absorbed by the body when it is consumed along with fat. Children and adults suffering from VAD, which is most commonly caused by malnutrition, often do not have access to fat in their diets.
Beta-carotene in Golden Rice degrades rapidly during storage and cooking
After six months of being stored in the presence of air at 25°C (a common temperature in most Asian countries), beta-carotene in Golden Rice degraded by 80-84%
The scientists also found that cooking Golden Rice degraded the beta-carotene by 17-24%.

Question 30

Economical and social reason

Answer 30

Since for-profit companies back genetically modified foods, some fear that their possible market dominance could negatively affect small-scale farmers, particularly poor farmers who cannot compete with large biotech companies for land and a share of the rice market.

Question 31

GMOs Risks

Answer 31

Risks include potential allergies or antibiotic resistance. There is also the possibility that genetically modified foods may enter the food supply inadvertently when GMO crops are planted near non-GMO crops, without the consumers’ knowledge. As genetically modified crops would have to be grown, there are concerns about the effect they would have on the surrounding environment.

Another issue concerns the spreading, escaping, or crossing of genes from genetically modified crops. This could create unwanted pesticide or herbicide resistance. As with human safety concerns, there is a possibility that other animals that eat genetically modified crops will be affected.

negatively affect small-scale farmers
