Q: Q: What is a thin layer of gas that surrounds earth called? Read this paragraph and choose the correct option from the provided answers: The atmosphere is a thin layer of gas that surrounds Earth. Climatologists study the atmosphere. These scientists work to understand the climate as it is now. They also study how climate will change in response to global warming. Choices: - the cloud cover - the dioxide - the wind cycle - the atmosphere A:
A: the atmosphere

Q: Q: What begins when a neuron receives a chemical stimulus? Read this paragraph and choose the correct option from the provided answers: A nerve impulse begins when a neuron receives a chemical stimulus. The impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that carry the nerve impulse to the next cell. Choices: - a induce impulse - a metabolism impulse - nerve reaction - a nerve impulse A:
A: a nerve impulse

Q: Q: An aqueous solution is a homogeneous mixture in which the most abundant component is what? Read this paragraph and choose the correct option from the provided answers: An aqueous solution is a homogeneous mixture in which the most abundant component is water. The other substance(s) are typically introduced in a solid or liquid form and mixed into the water until they are evenly distributed. For example, if we placed a sample of ethanol in water and mixed it homogeneously, we would have a solution. Table salt mixed with water is another example of a solution. More generally, a solution is a homogeneous mixture. The solution component that is present in the largest amount is called the solvent , and all other substances are referred to as solutes . In aqueous solutions, water is always the solvent. Choices: - air - oxygen - blood - water A:
A: water
