Question: Answer the following question given this paragraph: The Permian Period ended with Earth's second mass extinction. During this event, most of Earth's species went extinct. It was the most massive extinction ever recorded. It's not clear why it happened. One possible reason is that a very large meteorite struck Earth. Another possibility is the eruption of enormous volcanoes. Either event could create a huge amount of dust. The dust might block out sunlight for months. This would cool the planet and prevent photosynthesis. Q: What happened to earth's species during the permian period? A:
OPTIONS:
- evolution
- duplication
- division
- mass extinction
Answer: mass extinction

input with options: Answer the following question given this paragraph: The challenge of techniques used for proteomic analyses is the difficulty in detecting small quantities of proteins. Although mass spectrometry is good for detecting small amounts of proteins, variations in protein expression in diseased states can be difficult to discern. Proteins are naturally unstable molecules, which makes proteomic analysis much more difficult than genomic analysis. Q: The challenge of techniques used for proteomic analyses is the difficulty in detecting small quantities of what? A:
OPTIONS:
- bacteria
- acids
- particles
- proteins
output: proteins

Q: Answer the following question given this paragraph: Placental mammals are therian mammals in which a placenta develops during pregnancy. The placenta sustains the fetus while it grows inside the mother's uterus. Placental mammals give birth to relatively large and mature infants. Most mammals are placental mammals. Q: What does the placenta sustain during pregnancy? A:

OPTIONS:
- the heart
- the mother
- the endocrine system
- the fetus

A: the fetus

input: OPTIONS:
- overwhelm proteins
- resist proteins
- Raising Proteins
- antiviral proteins Now, answer this question: Answer the following question given this paragraph: Chapter 21 1 The three main components are the lymph vessels, the lymph nodes, and the lymph. 3 The bacterium is digested by the phagocyte's digestive enzymes (contained in its lysosomes). 5 B 7 C 9 A 11 D 13 C 15 B 17 B 19 D 21 D 23 B 25 C 27 B 29 C 31 D 33 A 35 B 37 B 39 The lymph enters through lymphatic capillaries, and then into larger lymphatic vessels. The lymph can only go in one direction due to valves in the vessels. The larger lymphatics merge to form trunks that enter into the blood via lymphatic ducts. 41 Interferons are produced in virally infected cells and cause them to secrete signals for surrounding cells to make antiviral proteins. C-reactive protein is induced to be made by the liver and will opsonize certain species of bacteria. 43 Antigen-specific clones are stimulated as their antigen receptor binds to antigen. They are then activated and proliferate, expanding their numbers. The result is a large number of antigen-specific lymphocytes. 45 IgM is an antigen receptor on naive B cells. Upon activation, naive B cells make IgM first. IgM is good at binding complement and thus has good antibacterial effects. IgM is replaced with other classes of antibodies later on in the primary response due to class switching. 47 Tuberculosis is caused by bacteria resistant to lysosomal enzymes in alveolar macrophages, resulting in chronic infection. The immune response to these bacteria actually causes most of the lung damage that is characteristic of this life-threatening disease. 49 Antibody response to the cell walls of -Streptococcus cross-reacts with the heart muscle. Complement is then activated and the heart is damaged, leading to abnormal function. Tolerance is broken because heart myosin antigens are similar to antigens on the - Streptococcus bacteria. Q: Interferons are produced in virally infected cells and cause them to secrete signals for surrounding cells to make what? A:
A:
output: antiviral proteins

Answer the following question given this paragraph: [PCl 3][Cl 2] (0.135)(0.135) = = 0.021 0.87 [PCl 5] The equilibrium constant calculated from the equilibrium concentrations is equal to the value of Kc given in the problem (when rounded to the proper number of significant figures). Thus, the calculated equilibrium concentrations check. Kc =. Q: Because of their reactivity, we do not find most representative metals as free elements where? A:

OPTIONS:
- in water
- in the atomospher
- underground
- in nature

Answer: in nature

Q: Answer the following question given this paragraph: In the oceans, plates move apart at mid-ocean ridges. Lava rises upward, erupts, and cools. Later, more lava erupts and pushes the original seafloor outward. This is seafloor spreading. Seafloor spreading forms new oceanic crust. The rising magma causes the ridge to be buoyant. This is why there is a mountain range running through the oceans. The plates pulling apart cause earthquakes. Q: What forms in the ocean from the seafloor spreading? A:

OPTIONS:
- underwater volcanoes
- tsunamis
- earthquakes
- new oceanic crust

A:
new oceanic crust
