Biotechnology Quiz

Genes are the basic units of heredity and are found in living organisms. They are responsible for transmitting traits from one generation to another. Genes are made up of DNA and are found in the cells of all living things, including plants, animals, and humans. They determine various characteristics and functions of living organisms.

Biotechnology is a field of science that involves the use of living organisms, such as plants, to develop and create useful products and technologies. Plants are a key component of biotechnology as they can be genetically modified to enhance their characteristics, improve crop yields, and develop new varieties with desirable traits. Additionally, plants are used in biotechnology for the production of pharmaceuticals, biofuels, and other valuable products. Therefore, the correct answer is "PLANTS".

Biotechnology does help the earth produce more nutritious food. Through biotechnology, scientists are able to genetically modify crops to enhance their nutritional content, such as increasing the levels of vitamins or minerals. This technology also allows for the development of crops with improved traits, such as disease resistance and drought tolerance, which can increase crop yields and ensure a more sustainable and reliable food supply. Therefore, biotechnology plays a crucial role in addressing global food security and improving the nutritional quality of the food we consume.

Biotechnology does help people produce more food on the same amount of land. Through biotechnology, scientists have developed genetically modified crops that are resistant to pests, diseases, and harsh environmental conditions. These crops have higher yields and require fewer resources such as water and pesticides. Additionally, biotechnology has also led to the development of improved agricultural practices such as precision farming and vertical farming, which maximize the use of limited land resources. Overall, biotechnology plays a crucial role in increasing food production and addressing global food security challenges.

A geneticist is a scientist who specifically studies genes and how traits are inherited. They analyze the structure, function, and behavior of genes, as well as how they are passed down from one generation to another. They may conduct research on genetic disorders, develop new treatments or therapies based on genetic information, and contribute to our understanding of the role genes play in various biological processes.

Biotechnology does help people reduce their use of pesticides. Through biotechnology, scientists have developed genetically modified crops that are resistant to pests, diseases, and herbicides. These crops require fewer pesticides to be applied, resulting in reduced pesticide usage. Additionally, biotechnology has also led to the development of biopesticides, which are derived from natural sources and are less harmful to the environment compared to chemical pesticides. Therefore, biotechnology plays a crucial role in reducing the reliance on pesticides and promoting sustainable agricultural practices.

Scientists using biotechnology have developed a type of cotton plant that protects itself from the larvae. This means that the cotton plant has been genetically modified to have a defense mechanism against larvae, which are known to cause damage to cotton crops. This development is significant as it can potentially reduce the need for chemical pesticides, leading to more sustainable and environmentally friendly cotton production.

Golden Rice is a genetically modified rice that has been bioengineered to produce beta-carotene, a precursor of vitamin A. Vitamin A deficiency is a leading cause of blindness in developing countries, particularly among children. Therefore, Golden Rice could help fight blindness by providing a source of vitamin A in areas where access to this nutrient is limited.

The 1/32 fraction signifies a very small portion of the Earth's crust that is arable land and suitable for agriculture. Arable land is land that can be used for farming and food production. This fraction indicates that a relatively small proportion of the Earth's total surface is available for growing food, as large portions of the Earth's surface are covered by oceans, deserts, mountains, and other features that are not conducive to agriculture.
