c. Explain why the produce from tropical plantations are profitable to the local communities that grow them, but not as profitable as finished goods. … While the communities do benefit from the production of the raw materials,
there is greater profit in the production of finished goods
.
What is the difference between selective breeding and genetic engineering in the development of food crops with desirable traits?
Selective breeding makes use of existing, naturally present gene variants in a species
?
and the natural process of breeding
. Genetic engineering involves a direct change to an organism’s genome in the laboratory. Gene variants made through genetic engineering can be passed from one generation to the next.
Which statement is true about selective breeding and genetic engineering?
Which statement is true about selective breeding and genetic engineering?
Both genetic engineering and selective breeding aim to develop crops with desirable traits
. In genetic engineering, only traits that are natively found in the genome of the species can be isolated and expressed.
Which of the following best explains why soil conservation is important to human agriculture quizlet?
Which of the following best explains why soil conservation is important to human agriculture? …
It is easier to prevent the degradation of old soil than it is to generate new soil.
Why is Dutch Agriculture critically dependent upon technology quizlet?
Why is Dutch agriculture critically dependent upon technology?
It produces almost 50% of the world supply of cut flowers and indoor plants
. It relies almost exclusively on genetically engineered crops. … Dutch fruit and vegetable production contributes to the global food supply.
What are 4 examples of selective breeding?
- cows that produce lots of milk.
- chickens that produce large eggs.
- wheat plants that produce lots of grain.
Is selective breeding better than genetic modification?
Benefits of genetic engineering:
Genetic modification is a faster and more efficient way of getting the same results as selective breeding
. Improves crop yields or crop quality, which is important in developing countries. This may help reduce hunger around the world.
What type of mutation will change only 1 amino acid?
A missense mutation
is when the change of a single base pair causes the substitution of a different amino acid in the resulting protein. This amino acid substitution may have no effect, or it may render the protein nonfunctional.
What is one of the benefits of using Rdna technology?
What is one way that recombinant DNA technology can benefit farmers? Using this technology, the
gene provides resistance to specific weed-killing chemicals
. The farmers can kill weeds with out killing the crops.
What are the benefits of GM foods in general?
- More nutritious food.
- Tastier food.
- Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)
- Less use of pesticides.
- Increased supply of food with reduced cost and longer shelf life.
- Faster growing plants and animals.
What causes soils and their horizons to differ?
A horizon is a soil layer with distinct physical and chemical properties that differ from those of other layers. Five factors account for soil formation:
parent material, climate, topography, biological factors, and time
.
Why Soil Conservation is important to human agriculture?
Soil conservation is proven to
increase the quality and quantity of crop yields over the long term
because it keeps topsoil in its place and preserves the long term productivity of the soil. To grow enough food not only for ourselves; but also for people in third would countries where there are food shortages.
How can pesticide use be harmful to human agriculture?
Pesticides kill useful soil microbes too. Use of pesticides results to make soil toxic for plant growth. Pesticides may reach animals or
human via food chain
and cause harm.
Why is Dutch agriculture critically dependent upon?
Why is Dutch agriculture critically dependent upon technology?
It produces almost 50% of the world supply of cut flowers and indoor plants
. It relies almost exclusively on genetically engineered crops. … Dutch fruit and vegetable production contributes to the global food supply.
Is Dutch agriculture is one of the most labor intensive types of agriculture in the world?
Soils rich in organic material are always highly fertile. Dutch agriculture is one of the most labor intensive types of agriculture in the world.
What type of agriculture is most characteristic of a Third World developing country?
Which type of agriculture is most characteristic of developing countries?
traditional subsistence agriculture
.
