Biodiversity and GMOs Concepts

This video tutorial, led by Doc Ken, covers Chapter 4 of Science, Technology, and Society, focusing on biodiversity and genetically modified organisms (GMOs). It outlines the interconnections between society, environment, and health, explains genetic engineering, and discusses the ethical implications of GMOs. The tutorial delves into biodiversity, highlighting ecosystem, species, and genetic diversity, and emphasizes the importance of biodiversity for human survival. It also explores the benefits and concerns of GMOs and introduces the Cartagena Protocol on Biosafety, which ensures the safe handling of living modified organisms.

What is one of the learning outcomes of this chapter?

• To identify the types of ecosystems

• To explain the process of genetic engineering

• To describe the history of biodiversity

• To list the species in a forest

What does biodiversity refer to?

• The genetic makeup of a single species

• The number of ecosystems in a region

• The variety of life on Earth

• The number of plants in a forest

Which of the following is NOT a type of biodiversity?

• Ecosystem diversity

• Species diversity

• Genetic diversity

• Climate diversity

What does ecosystem diversity include?

• The genetic differences within a species

• The number of species in a forest

• The number of plants in a desert

• The variation in ecosystems over the planet

How is species richness defined?

• The number of species in a particular location

• The number of ecosystems in a region

• The genetic variation within a species

• The abundance of a single species

What does genetic diversity refer to?

• The abundance of a single species

• The variety of ecosystems on Earth

• The genetic differences within a species

• The number of species in a location

What is a genetically modified organism (GMO)?

• An organism that is extinct

• An organism that has not been modified

• An organism whose genetic material has been altered using genetic engineering

• An organism with naturally occurring genes

Which of the following is a potential benefit of GMOs?

• Increased use of pesticides

• Reduced food supply

• Faster growing plants and animals

• Less nutritious food

What is a concern some people have about GMOs?

• They grow slower than natural organisms

• They can cause unexpected genetic changes

• They are more nutritious

• They are always safe to consume

What is the purpose of the Cartagena Protocol on Biosafety?

• To promote the use of GMOs

• To ensure the safe handling of living modified organisms

• To increase the number of species on Earth

• To ban all genetically modified organisms
