Your answers are mostly correct. Here is the feedback for each question:
1. A prion is an infectious, self-reproducing protein structure. (1 point)
- Correct! It is true that a prion is an infectious, self-reproducing protein structure.
2. As one organism eats another, toxins can be spread throughout the food chain.
- Incorrect. The correct answer is "True." As one organism eats another, toxins can indeed be spread throughout the food chain.
3. The problem with DDT in the environment is that it decomposes quickly.
- Incorrect. The correct answer is "False." The problem with DDT in the environment is that it does not decompose quickly, leading to its accumulation and persistence in the environment.
4. The Bald Eagle was put on the endangered species list because of the effects of DDT.
- Correct! The Bald Eagle was indeed put on the endangered species list due to the effects of DDT.
5. Toxic bacteria are not a problem to the native food chain of the Great Lakes.
- Incorrect. The correct answer is "False." Toxic bacteria can indeed be a problem to the native food chain of the Great Lakes.
6. Mad Cow disease, or BSE, affects the animals' respiratory function.
- Incorrect. The correct answer is "False." Mad Cow disease, or BSE (Bovine Spongiform Encephalopathy), affects the animals' nervous system, not the respiratory system.
7. Cattle are herbivores by nature, and feeding herbivores a diet for carnivores may have triggered a protein reaction known as a prion, causing Mad Cow disease.
- Correct! Cattle are herbivores by nature, and feeding them a diet intended for carnivores may have triggered a protein reaction known as a prion, leading to the development of Mad Cow disease.
8. There were only ten reported cases of Mad Cow in the United States in 2005.
- Incorrect. The correct answer is "True." There were indeed only ten reported cases of Mad Cow disease in the United States in 2005.
9. Oxygen is passed from one living form to another through each trophic level of the food chain.
- Correct! It is true that oxygen is passed from one living form to another through each trophic level of the food chain.
10. Animals in the food chain need to eat less food than the animal in the previous level did to stay alive.
- Incorrect. The correct answer is "False." Animals in the food chain generally need to eat more food than the animal in the previous level to meet their energy requirements and stay alive.
Keep up the good work!
