Answer the following question given this paragraph: Carbon can form two different compounds with oxygen. Q: What element can form two different compounds with oxygen? Choices: - dioxide - H20 - hydrogen - carbon A:
carbon
Answer the following question given this paragraph: the law of conservation of matter, which says that matter cannot be created or destroyed. This means we must have the same number of protons and neutrons on both sides of the nuclear equation. If our uranium nucleus loses 2 protons, there are 90 protons remaining, identifying the element as thorium. Moreover, if we lose four nuclear particles of the original 235, there are 231 remaining. Thus we use subtraction to identify the isotope of the Th atomin this case,. Q: The law of conservation of matter, which says that matter cannot be created or this? Choices: - abandoned - damaged - stopped - destroyed A:
destroyed
Q: Answer the following question given this paragraph: Competitive Exclusion Principle Resources are often limited within a habitat and multiple species may compete to obtain them. All species have an ecological niche in the ecosystem, which describes how they acquire the resources they need and how they interact with other species in the community. The competitive exclusion principle states that two species cannot occupy the same niche in a habitat. In other words, different species cannot coexist in a community if they are competing for all the same resources. An example of this principle is shown in Figure 45.24, with two protozoan species, Paramecium aurelia and Paramecium caudatum. When grown individually in the laboratory, they both thrive. But when they are placed together in the same test tube (habitat), P. aurelia outcompetes P. caudatum for food, leading to the latter's eventual extinction. Q: Which principle states that two species cannot occupy the same niche in a habitat? Choices: - complete exclusion - produce exclusion - tough exclusion - competitive exclusion A:
A: competitive exclusion
Question: Answer the following question given this paragraph: Fission Occurs when a parent cell splits into two identical daughter cells of the same size. Bacteria, Protists, Unicellular Fungi. Q: What occurs when a parent cell splits into two identical daughter cells of the same size? Choices: - diffusion - division - fusion - fission A:
Answer: fission

Answer the following question given this paragraph: Tornadoes may also come from hurricanes. A hurricane ( Figure below ) is an enormous storm with high winds and heavy rains. Hurricanes may be hundreds of kilometers wide. They may travel for thousands of kilometers. The storm's wind speeds may be greater than 251 kilometers (156 miles) per hour. Hurricanes develop from tropical cyclones. Hurricanes are called typhoons in the Pacific. Q: What are hurricanes called in the pacific? Choices: - tornados - rainstorms - twisters - typhoons A:
**Answer**
typhoons

Answer the following question given this paragraph: Synthetic carbon polymers are produced in labs or factories. Plastics are common examples of synthetic carbon polymers. You are probably familiar with the plastic called polyethylene. All of the plastic items pictured in the Figure below are made of polyethylene. It consists of repeating monomers of ethylene (C 2 H 4 ). Structural formulas for ethylene and polyethylene are also shown in the Figure below .
