Answer the following question given this paragraph: Rainwater absorbs carbon dioxide (CO 2 ) as it falls. The CO 2 combines with water to form carbonic acid. The slightly acidic water is especially good at dissolving the rock limestone. Groundwater creates landforms by dissolving away rock. Q: Rainwater absorbs carbon dioxide (co 2 ) as it falls. the co 2 combines with water to form what? A:

OPTIONS:
- carbon monoxide
- nitrate acid
- methane gas
- carbonic acid

Answer: carbonic acid

Problem: OPTIONS:
- electrolysis
- budding
- mitosis
- meiosis
Q: Answer the following question given this paragraph: Mitosis vs. Meiosis Comparison. Mitosis produces two diploid daughter cells, genetically identical to the parent cell. Meiosis produces four haploid daughter cells, each genetically unique. See How Cells Divide: Mitosis vs. Meiosis at http://www. pbs. org/wgbh/nova/miracle/divide. html for an animation comparing the two processes. Q: What process produces four haploid daughter cells, each genetically unique? A:
Answer: meiosis

Problem:OPTIONS:
- form hot spot
- oceanic hot spot
- deeper hot spot
- continental hot spot

Answer the following question given this paragraph: Hot spots are found within continents, but not as commonly as within oceans. The Yellowstone hot spot is a famous example of a continental hot spot. Q: The yellowstone hot spot is a famous example of a what? A:
****
A: continental hot spot

Answer the following question given this paragraph: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two lipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Q: What is a double membrane of the nucleus that encloses the genetic material? A:
OPTIONS:
- cell wall
- cell membrane
- nuclear wall
- nuclear enevelope
nuclear enevelope

Answer the following question given this paragraph: Avian Birds face special challenges when it comes to obtaining nutrition from food. They do not have teeth and so their digestive system, shown in Figure 34.7, must be able to process un-masticated food. Birds have evolved a variety of beak types that reflect the vast variety in their diet, ranging from seeds and insects to fruits and nuts. Because most birds fly, their metabolic rates are high in order to efficiently process food and keep their body weight low. The stomach of birds has two chambers: the proventriculus, where gastric juices are produced to digest the food before it enters the stomach, and the gizzard, where the food is stored, soaked, and mechanically ground. The undigested material forms food pellets that are sometimes regurgitated. Most of the chemical digestion and absorption happens in the intestine and the waste is excreted through the cloaca. Q: In which part of a bird stomach is food stored, soaked and mechanically ground? A:
OPTIONS:
- pancreas
- digestion
- Gall bladder
- gizzard

Answer: gizzard

input with options: Answer the following question given this paragraph: Another major cause of extinction is global warming , which is also known as global climate change. During the past century, the Earth's average temperature has risen by almost 1C (about 1.3F). You may not think that is significant, but to organisms that live in the wild and are constantly adapting to their environments, any climate change can be hazardous. Recall that burning fossil fuels releases gasses into the atmosphere that warm the Earth. Our increased use of fossil fuels, such as coal and oil, is changing the Earth's climate. Any long-term change in the climate can destroy the habitat of a species. Even a brief change in climate may be too stressful for an organism to survive. For example, if the seas increase in temperature, even briefly, it may be too warm for certain types of fish to reproduce. Q: Another major cause of extinction is global warming , which is also known as? A:
OPTIONS:
- sudden climate change
- rapid climate change
- regional climate change
- global climate change
output:
global climate change
