(Intr 8.2) A GMO is a
- A.
Genetically Made Organic
- B.
Genetically Manufactured Organic
- C.
Genetically Modified Organism
- D.
Generic Modified Organism
Correct Answer
C. Genetically Modified OrganismExplanation
A GMO refers to a Genetically Modified Organism, which is an organism whose genetic material has been altered using genetic engineering techniques. This can involve the insertion, deletion, or modification of genes to introduce new traits or enhance existing ones. GMOs are commonly used in agriculture to improve crop yield, increase resistance to pests or diseases, and enhance nutritional content. They are also used in scientific research and the production of pharmaceuticals. The term "Genetically Made Organic" and "Genetically Manufactured Organic" are not accurate descriptions of GMOs, and "Generic Modified Organism" is not a recognized term.Rate this question:
-
- 22.
(Intr 8.2) An example of a GMO is
- A.
Frost resistant strawberries.
- B.
Bt "caterpillar killing" corn.
- C.
All the above.
- D.
None of the above.
Correct Answer
C. All the above.Explanation
The correct answer is "all the above". This is because both frost-resistant strawberries and Bt "caterpillar killing" corn are examples of genetically modified organisms (GMOs). GMOs are organisms whose genetic material has been altered using genetic engineering techniques. In the case of frost-resistant strawberries, genes from other organisms may have been inserted to make the strawberries more resistant to frost. Similarly, Bt "caterpillar killing" corn has been genetically modified to produce a toxin that kills certain pests. Therefore, both examples given in the question are valid examples of GMOs.Rate this question:

(Intr 8.3) Which do you think is farm animal abuse?
- A.
Free roaming chickens in an open barnyard.
- B.
Egg laying hens kept in stacked cages.
- C.
Feeding antibiotics to chickens.
- D.
Branding.
Correct Answer
A. Free roaming chickens in an open barnyard.Explanation
The correct answer is free roaming chickens in an open barnyard. This is considered farm animal abuse because it allows the chickens to be exposed to potential predators, harsh weather conditions, and lack of proper care and nutrition. It also increases the risk of disease transmission and injury to the chickens. Keeping egg laying hens in stacked cages may be considered unethical and inhumane, but it is not classified as abuse. Feeding antibiotics to chickens is a common practice to prevent and treat diseases, and branding is a method used for identification purposes.Rate this question:

- B.
Pitil.
- C.
Stamen.
- D.
Fruit.
- E.
Flower.
- F.

Correct Answer
A. Light, air, water, soil.Explanation
Light, air, water, and soil are all essential for plant growth. Light is necessary for photosynthesis, the process by which plants convert sunlight into energy. Air provides carbon dioxide for photosynthesis and oxygen for respiration. Water is crucial for transporting nutrients and minerals throughout the plant. Soil contains essential nutrients and minerals that plants need to grow and thrive. Therefore, all four elements are required for optimal plant growth.Rate this question:

- C.
Using good insects to kill crop damaging insects.
- D.
Fertilizing crops only with animal manures.
Correct Answer
C. Using good insects to kill crop damaging insects.Explanation
Using good insects to kill crop damaging insects is an example of good plant crop environmental stewardship because it promotes natural pest control methods. By introducing beneficial insects that prey on crop damaging insects, farmers can reduce the need for chemical pesticides, which can have harmful effects on the environment and human health. This approach is also more sustainable and helps to maintain a balanced ecosystem within the agricultural system.Rate this question:

- D.
Matching farm animal production to the crops grown.
Correct Answer
A. Using GPS system to apply fertilizer to crop fields.Explanation
Precision farming technology involves using advanced tools and techniques to optimize agricultural practices. One such example is the use of GPS systems to apply fertilizer to crop fields. By accurately mapping the fields and tracking the precise location of the equipment, farmers can ensure that fertilizers are applied only where needed, minimizing waste and maximizing crop yield. This technology enables farmers to target specific areas with the right amount of nutrients, resulting in efficient resource utilization and improved crop health.Rate this question:

(Plant 5.2) What is the difference between genetically modified and selective breeding?
- A.
Genetic modification is used in plants, selective breeding in animals.
- B.
Genetic modification is done in a lab, selective breeding in a greenhouse.
- C.
Neither one of these is a good answer.
Correct Answer
B. Genetic modification is done in a lab, selective breeding in a greenhouse.Explanation
Genetic modification is the process of altering the genetic makeup of an organism by introducing specific genes from another organism. This is typically done in a laboratory setting using advanced techniques such as gene splicing. On the other hand, selective breeding is a process where humans intentionally choose organisms with desirable traits and breed them together to produce offspring with those traits. This process occurs in a controlled environment like a greenhouse, where plants or animals are carefully selected and bred over multiple generations. Therefore, the correct answer states that genetic modification is done in a lab, while selective breeding takes place in a greenhouse.Rate this question:

(Plant 5.3) The suffix "cide" means to kill. Which of these kills weeds?
- A.
Pesticide.
- B.
Insecticide.
- C.
Fungicide.
- D.
Rhodenticide.
Correct Answer
A. Pesticide.Explanation
The suffix "cide" means to kill, and pesticide is a substance used to kill pests, including weeds. Insecticide is used to kill insects, fungicide is used to kill fungi, and rodenticide is used to kill rodents. Therefore, out of the given options, pesticide is the correct answer as it specifically targets and kills weeds.Rate this question:

(Plant 5.3) How can insects can damage a plant?
- A.
Eating it and spreading plant diseases.
- B.
Spreading plant diseases and using up plant nutrients.
- C.
Attrating birds that feed on them.
- D.
Using up water that the plant needs.
Correct Answer
A. Eating it and spreading plant diseases.Explanation
Insects can damage a plant by eating it and spreading plant diseases. When insects feed on plants, they can consume large amounts of plant tissue, causing physical damage. Additionally, some insects act as carriers for plant diseases, spreading pathogens from one plant to another as they move and feed. This can result in the spread of diseases that can weaken or kill plants. Therefore, both eating plants and spreading diseases are ways in which insects can cause damage to plants.Rate this question:
