Answer the following question given this paragraph: A community is the biotic component of an ecosystem. It consists of the populations of all the species that live in the same area. Populations in communities often interact with each other. Community interactions are important factors in natural selection. They help shape the evolution of the interacting species. Types of community interactions include predation, competition, and symbiosis. You'll read about each type of interaction in this lesson. Q: Community interactions are important factors in what? A:

OPTIONS:
- natural process
- natural change
- natural resources
- natural selection

Answer: natural selection

Problem: OPTIONS:
- fold
- split
- duplicate
- divide
Q: Answer the following question given this paragraph: Aging occurs as cells lose their ability to divide. Q: Aging occurs as cells lose their ability to do what? A:
Answer: divide

Problem:OPTIONS:
- toxic water
- chemical water
- gaseous water
- liquid water

Answer the following question given this paragraph: Liquid water is formed when water vapor condenses (i. e. , H 2 O(g) H 2 O(l) or when ice melts (i. e. , H 2 O(s) H 2 O(l)). Because water is a molecular substance, it is a poor conductor of electricity in its pure form. However, as we will see later, its conductivity can be improved by the addition of certain substances. Water molecules are polar, and this overall polarity gives rise to many of the properties of water. For example, an interesting effect is seen when water is placed in a static electric field, as shown in the Figure below and the video below. This phenomenon can be explained in terms of the polarity of water molecules. Q: What is type of substance is formed when water vapor condenses or when ice melts? A:
****
A: liquid water

Answer the following question given this paragraph: There is a lot of volcanic activity at divergent plate boundaries in the oceans. As the plates pull away from each other, they create deep fissures. Molten lava erupts through these cracks. The East Pacific Rise is a divergent plate boundary in the Pacific Ocean ( Figure below ). The Mid-Atlantic Ridge is a divergent plate boundary in the Atlantic Ocean. Q: In what ocean is the mid-atlantic ridge located? A:
OPTIONS:
- indian ocean
- pacific ocean
- arctic ocean
- atlantic ocean
atlantic ocean

Answer the following question given this paragraph: H2 + O2 H2O This is an example of a chemical equation, which is a concise way of representing a chemical reaction. The initial substances are called reactants, and the final substances are called products. Unfortunately, it is also an incomplete chemical equation. The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products. If we count the number of hydrogen atoms in the reactants and products, we find two hydrogen atoms. But if we count the number of oxygen atoms in the reactants and products, we find that there are two oxygen atoms in the reactants but only one oxygen atom in the products. What can we do? Can we change the subscripts in the formula for water so that it has two oxygen atoms in it? No; you cannot change the formulas of individual substances because the chemical formula for a given substance is characteristic of that substance. What you can do, however, is to change the number of molecules that react or are produced. We do this one element at a time, going from one side of the reaction to the other, changing the number of molecules of a substance until all elements have the same number of atoms on each side. To accommodate the two oxygen atoms as reactants, let us assume that we have two water molecules as products:. Q: Initial substances are called reactants, and the final substances are called what? A:
OPTIONS:
- exports
- imports
- reactors
- products

Answer:
products
