Answer the following question given this paragraph: Chemical digestion could not take place without the help of digestive enzymes and other substances secreted into the GI tract. An enzyme is a protein that speeds up a biochemical reaction. Digestive enzymes speed up the reactions of chemical digestion. Table below lists a few digestive enzymes, the organs that produce them, and their functions in digestion. Q: What speeds up the reactions of chemical digestion? A:

OPTIONS:
- protein catalysts
- electrical enzymes
- stomach acids
- digestive enzymes

Answer: digestive enzymes

Problem: OPTIONS:
- decomposition
- precipitation
- carbonation
- oxidation
Q: Answer the following question given this paragraph: Oxidation often involves the loss of hydrogen, the gain of oxygen, or the loss of electrons. Q: What often involves the loss of hydrogen, the gain of oxygen, or the loss of electrons? A:
Answer: oxidation

Problem:OPTIONS:
- arteries
- muscles
- lungs
- ventricles

Answer the following question given this paragraph: Q: Where does much of the blood that enters the atria flow? A:
****
A: ventricles

Answer the following question given this paragraph: Chemical cells are found in batteries. They produce voltage by means of chemical reactions. Chemical cells have two electrodes, which are strips of different materials, such as zinc and carbon. The electrodes are suspended in an electrolyte. This is a substance that contains free ions, which can carry electric current. The electrolyte may be either a paste, in which case the cell is called a dry cell, or a liquid, in which case the cell is called a wet cell. Flashlight batteries contain dry cells. Car batteries contain wet cells. Q: Batteries produce voltage through what type of reaction? A:
OPTIONS:
- liquid
- non-chemical
- thermal
- chemical
chemical

Answer the following question given this paragraph: Another related process is effusion. Effusion is the process of a confined gas escaping through a tiny hole in its container. Effusion can be observed by the fact that a helium-filled balloon will stop floating and sink to the floor after a day or so. This is because the helium gas effuses through tiny pores in the balloon. Both diffusion and effusion are related to the speed at which various gas molecules move. Gases that have a lower molar mass effuse and diffuse at a faster rate than gases that have a higher molar mass. While they are similar processes, there is a key difference between diffusion and effusion. Diffusion describes the process of a gas spreading out at a constant pressure, such as throughout a room. Effusion, on the other hand, describes the process of a gas spreading out from a high pressure surroundings to lower pressure surroundings. Q: What is the process of a confined gas escaping through a tiny hole in its container called? A:
OPTIONS:
- effluent
- dissipation
- dilution
- effusion

Answer: effusion

input with options: Answer the following question given this paragraph: Neptune's appearance changes due to its turbulent atmosphere. Winds are stronger than on any other planet in the solar system. Wind speeds can reach 1,100 km/h (700 mph). This is close to the speed of sound! The rapid winds surprised astronomers. This is because Neptune receives little energy from the Sun to power weather systems. It is not surprising that Neptune is one of the coldest places in the solar system. Temperatures at the top of the clouds are about 218C (360F). Q: Why does neptune's appearance change? A:
OPTIONS:
- the seasons
- the changing orbit
- the speed of rotation
- turbulent atmosphere
output:
turbulent atmosphere
