What is the primary goal of biotechnology in agriculture?

  1. To increase crop yields

  2. To reduce the use of pesticides and fertilizers

  3. To improve the nutritional value of crops

  4. To create crops that are resistant to pests and diseases


Correct Option:
Explanation:

Biotechnology in agriculture aims to achieve multiple goals, including increasing crop yields, reducing the use of pesticides and fertilizers, improving the nutritional value of crops, and creating crops that are resistant to pests and diseases.

Which technique is commonly used in biotechnology to transfer genes from one organism to another?

  1. Gene editing

  2. Genetic engineering

  3. Recombinant DNA technology

  4. Gene therapy


Correct Option: C
Explanation:

Recombinant DNA technology is a widely used technique in biotechnology to transfer genes from one organism to another. It involves isolating a gene of interest, combining it with a carrier DNA molecule, and introducing it into a host organism.

What is the term used for crops that have been genetically modified to resist pests and diseases?

  1. Transgenic crops

  2. Genetically modified crops (GMCs)

  3. Bioengineered crops

  4. Bt crops


Correct Option:
Explanation:

Transgenic crops, genetically modified crops (GMCs), bioengineered crops, and Bt crops are all terms used to describe crops that have been genetically modified to resist pests and diseases.

Which crop was the first genetically modified crop to be commercialized?

  1. Soybean

  2. Corn

  3. Cotton

  4. Canola


Correct Option:
Explanation:

The first genetically modified crop to be commercialized was the Flavr Savr tomato, which was developed in 1994. It had a longer shelf life and maintained its flavor better than conventional tomatoes.

What is the role of CRISPR-Cas9 in biotechnology?

  1. It is a gene editing tool

  2. It is a diagnostic tool for genetic diseases

  3. It is a vaccine development tool

  4. It is a DNA sequencing tool


Correct Option: A
Explanation:

CRISPR-Cas9 is a powerful gene editing tool that allows scientists to precisely modify the DNA of organisms. It has applications in agriculture, medicine, and other fields.

Which agricultural practice aims to reduce the environmental impact of farming?

  1. Sustainable agriculture

  2. Organic farming

  3. Precision agriculture

  4. Conservation agriculture


Correct Option:
Explanation:

Sustainable agriculture, organic farming, precision agriculture, and conservation agriculture are all practices that aim to reduce the environmental impact of farming by minimizing the use of pesticides and fertilizers, conserving soil and water, and promoting biodiversity.

What is the term used for the process of introducing beneficial microorganisms into the soil to improve plant growth?

  1. Bioremediation

  2. Bioaugmentation

  3. Phytoremediation

  4. Mycoremediation


Correct Option: B
Explanation:

Bioaugmentation is the process of introducing beneficial microorganisms into the soil to improve plant growth. These microorganisms can help fix nitrogen, solubilize phosphorus, and suppress plant pathogens.

Which technology allows farmers to apply pesticides and fertilizers more precisely to crops?

  1. Satellite imagery

  2. Drones

  3. GPS-guided tractors

  4. Variable rate technology


Correct Option: D
Explanation:

Variable rate technology allows farmers to apply pesticides and fertilizers more precisely to crops by adjusting the application rate based on factors such as soil type, crop health, and weather conditions.

What is the term used for the process of using plants to remove pollutants from the environment?

  1. Phytoremediation

  2. Bioremediation

  3. Mycoremediation

  4. Bioaugmentation


Correct Option: A
Explanation:

Phytoremediation is the process of using plants to remove pollutants from the environment. Plants can absorb and accumulate pollutants from the soil, water, and air.
