Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering involves the transfer of genes from one organism to another, often across species boundaries, to create genetically modified organisms.

Multiple choice

Which of the following is NOT a potential benefit of genetically modified crops?

  1. Increased resistance to pests and diseases

  2. Improved nutritional value

  3. Reduced reliance on chemical inputs

  4. Loss of traditional crop varieties
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetically modified crops have the potential to offer increased resistance to pests and diseases, improved nutritional value, and reduced reliance on chemical inputs, but they do not directly lead to the loss of traditional crop varieties.

  4. By investigating the role of marine microbes in bioremediation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Marine metagenomics offers the potential to discover novel genes encoding enzymes with unique properties, which can be harnessed for various industrial applications, such as biofuel production and bioremediation.

Multiple choice

What is the concept of 'biopower'?

  1. The power to control and manipulate life

  2. The power to produce knowledge and truth

  3. The power to create social order and stability

  4. The power to promote individual freedom and autonomy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Foucault's concept of 'biopower' refers to the power to control and manipulate life. He believed that biopower is a form of power that is exercised over the population as a whole, rather than over individuals. He argued that biopower is used to regulate and control the birth rate, the death rate, and the overall health of the population. He also argued that biopower is used to create and maintain social norms and values.
