Problem: OPTIONS:
- h2O hybridization
- ionic hybridization
- nh3 hybridization
- sp 3 hybridization
Q: Answer the following question given this paragraph: The methane and ammonia examples illustrate the connection between orbital hybridization and the VSEPR model. The electron domain geometry predicted by VSEPR leads directly to the type of hybrid orbitals that must be formed to accommodate that geometry. Both methane and ammonia have tetrahedral electron domain geometries and thus both undergo sp 3 hybridization. Q: What type of hybridization does ammonia undergo? A:
Answer: sp 3 hybridization

Problem:OPTIONS:
- sediments
- fluids
- stem cells
- organisms

Answer the following question given this paragraph: Q: In biological augmentation, ecologists use what to add essential materials to ecosystems? A:
****
A: organisms

Answer the following question given this paragraph: Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. Q: How do oceans help control global warming? A:
OPTIONS:
- releasing oxygen
- reflecting light
- Cooling air
- absorbing carbon dioxide
absorbing carbon dioxide

Answer the following question given this paragraph: No, not all birds can fly. And not all birds have wings. This penguin is a good example. Their wings have evolved into flippers, adapted for swimming instead of flying. The kiwi of New Zealand is another bird without wings. Q: What is caused by atoms or ions when they share or transfer valance electrons? A:
OPTIONS:
- loss of charge
- gain of charge
- force of repulsion
- force of attraction

Answer: force of attraction

Question: Answer the following question given this paragraph: An underground layer of rock that is saturated with groundwater is called an aquifer . A diagram of an aquifer is pictured below ( Figure below ). Aquifers are generally found in porous rock, such as sandstone. Water infiltrates the aquifer from the surface. The water that enters the aquifer is called recharge . Q: What is the name for an underground layer of rock that is saturated with groundwater? A:
OPTIONS:
- gradient
- aqueous cavity
- artesian well
- aquifer
Answer: aquifer

input: OPTIONS:
- linear mixture
- particulate mixture
- compact mixture
- homogeneous mixture Now, answer this question: Answer the following question given this paragraph: Gases mix homogeneously when confined to same container. When several gases are added to a container, the individual gas particles mix freely, forming a homogeneous mixture in which each type of gas is randomly distributed throughout all the available volume. Q: What is formed when different gases are confined to the same container? A:
A:
output:
homogeneous mixture
