Answer the following question given this paragraph: The saguaro cactus pictured in Figure below has adapted in all three ways. When it was still a very small plant, just a few inches high, its shallow roots already reached out as much as 2 meters (7 feet) from the base of the stem. By now, its root system is much more widespread. It allows the cactus to gather as much moisture as possible from rare rainfalls. The saguaro doesn't have any leaves to lose water by transpiration. It also has a large, barrel-shaped stem that can store a lot of water. Thorns protect the stem from thirsty animals that might try to get at the water inside. Q: The saguaro doesn't have any leaves to lose water by which process? A:
****
A: transpiration

Answer the following question given this paragraph: All chemical reactions, even exothermic reactions, need a certain amount of energy to get started. This energy is called activation energy . For example, activation energy is needed to start a car. Turning the key causes a spark that activates the burning of gasoline in the engine. The combustion of gas won't occur without the spark of energy to begin the reaction. Q: The energy a chemical reaction needs to get started is called what kind of energy? A:
OPTIONS:
- function
- conduction
- fusion
- activation
activation

Answer the following question given this paragraph: A hydration reaction is the opposite of a dehydration reaction. A hydration reaction adds water to an organic molecule and breaks the large molecule into smaller molecules. Hydration reactions occur in an acidic water solution. An example of hydration reaction is the breaking of peptide bonds in polypeptides. A hydroxide ion (OH - ) and a hydrogen ion (H + ) (both from a water molecule) bond to the carbon atoms that formed the peptide bond. This breaks the peptide bond and results in two amino acids. Q: What kind of reaction adds water to an organic molecule and breaks the large molecule into smaller molecules? A:
OPTIONS:
- heat reaction
- supplementation reaction
- aerobic reaction
- hydration reaction

Answer: hydration reaction

Question: Answer the following question given this paragraph: transports an amino acid varies. Most carriers are linked to the active transport of sodium. Short chains of two amino acids (dipeptides) or three amino acids (tripeptides) are also transported actively. However, after they enter the absorptive epithelial cells, they are broken down into their amino acids before leaving the cell and entering the capillary blood via diffusion. Q: Short chains of two amino acids (dipeptides) or three amino acids (tripeptides) are also transported actively. however, after they enter the absorptive epithelial cells, they are broken down into their amino acids before leaving the cell and entering the capillary blood via what? A:
OPTIONS:
- osmosis
- convection
- absorption
- diffusion
Answer: diffusion

input with options: Answer the following question given this paragraph: Q: Vertical layering is an important feature of the terrestrial type of what kind of community? A:
OPTIONS:
- habitat
- environment
- ecosystem
- biome
output: biome

Problem: OPTIONS:
- fluid weathering
- chemical erosion
- chemical weathering
- mechanical weathering
Q: Answer the following question given this paragraph: Mechanical weathering breaks rock into smaller pieces. These smaller pieces are just like the bigger rock; they're just smaller! The rock has broken without changing its composition. The smaller pieces have the same minerals in the same proportions. You could use the expression "a chip off the old block" to describe mechanical weathering! The main agents of mechanical weathering are water, ice, and wind. Q: What type of weathering breaks rock into smaller pieces? A:
Answer:
mechanical weathering
