Answer the following question given this paragraph: Natural events, like storms, volcanic eruptions and earthquakes can cause major changes in water quality. But human-caused contaminants have a much greater impact on the quality of the water supply. Water is considered polluted either when it does not support a human use, like clean drinking water, or a use for other animals and plants. The overgrowth of algae, known as an algal bloom , can result from the runoff of fertilizer into bodies of water. This excess of nutrients allows the algae to grow beyond control, bring harm to the rest of the ecosystem. Q: What has a bigger impact on water quality, natural events or human activity? Choices: - water quality - all of the above - natural events - human activity A:
human activity
Q: Answer the following question given this paragraph: Can Snail Venom Be Used as a Pharmacological Painkiller? Marine snails of the genus Conus (Figure 28.25) attack prey with a venomous sting. The toxin released, known as conotoxin, is a peptide with internal disulfide linkages. Conotoxins can bring about paralysis in humans, indicating that this toxin attacks neurological targets. Some conotoxins have been shown to block neuronal ion channels. These findings have led researchers to study conotoxins for possible medical applications. Conotoxins are an exciting area of potential pharmacological development, since these peptides may be possibly modified and used in specific medical conditions to inhibit the activity of specific neurons. For example, these toxins may be used to induce paralysis in muscles in specific health applications, similar to the use of botulinum toxin. Since the entire spectrum of conotoxins, as well as their mechanisms of action, are not completely known, the study of their potential applications is still in its infancy. Most research to date has focused on their use to treat neurological diseases. They have also shown some efficacy in relieving chronic pain, and the pain associated with conditions like sciatica and shingles. The study and use of biotoxinstoxins derived from living organismsare an excellent example of the application of biological science to modern medicine. Q: Conotoxins released by certain marine snails can bring about paralysis in humans, indicating that this toxin attacks what system? Choices: - cerebral - circulatory - cardiovascular - neurological A:
A: neurological

Answer the following question given this paragraph: A binary molecular compound is a molecular compound that is composed of two elements. The elements that combine to form binary molecular compounds are both nonmetal atoms. This contrasts with ionic compounds, which were formed from a metal ion and a nonmetal ion. Therefore, binary molecular compounds are different because ionic charges cannot be used to name them or to write their formulas. Another difference is that two nonmetal atoms will frequently combine with one another in a variety of ratios. Consider the elements nitrogen and oxygen. They combine to make several compounds including NO, NO 2 , and N 2 O. They all can't be called nitrogen oxide. How would someone know which one you were talking about? Each of the three compounds has very different properties and reactivity. A system to distinguish between compounds such as these is necessary. Q: A binary molecular compound is made up of two of what? Choices: - compounds - cells - wafers - elements A:
**Answer**
elements
Answer the following question given this paragraph: Nuclear symbols are used to write nuclear equations for radioactive decay. Let's consider the example of the beta-minus decay of thorium-234 to protactinium-234. This reaction is represented by the equation:. Q: What are used to write nuclear equations for radioactive decay? Choices: - trigonometric symbols - critical symbols - radioactive symbols - nuclear symbols A:
nuclear symbols
