Answer the following question given this paragraph: Q: What two forces tend to keep an animal stationary and thus oppose locomotion? Choices: - workload and gravity - thickness and gravity - stength and gravity - friction and gravity A:
friction and gravity
(Question)
Answer the following question given this paragraph: Another major problem caused by air pollution is global climate change. Gases such as carbon dioxide from the burning of fossil fuels increase the natural greenhouse effect. This raises the temperature of Earth's surface. Q: What gas is contributing to the greenhouse effect? Choices: - nitrogen - oxygen - sodium chloride - carbon dioxide A:
(Answer)
carbon dioxide
Ques: Answer the following question given this paragraph: The autonomic nervous system serves as the relay between the CNS and the internal organs. It controls the lungs, the heart, smooth muscle, and exocrine and endocrine glands. The autonomic nervous system controls these organs largely without conscious control; it can continuously monitor the conditions of these different systems and implement changes as needed. Signaling to the target tissue usually involves two synapses: a preganglionic neuron (originating in the CNS) synapses to a neuron in a ganglion that, in turn, synapses on the target organ, as illustrated in Figure 35.26. There are two divisions of the autonomic nervous system that often have opposing effects: the sympathetic nervous system and the parasympathetic nervous system. Sympathetic Nervous System The sympathetic nervous system is responsible for the "fight or flight" response that occurs when an animal encounters a dangerous situation. One way to remember this is to think of the surprise a person feels when encountering a snake ("snake" and "sympathetic" both begin with "s"). Examples of functions controlled by the sympathetic nervous system include an accelerated heart rate and inhibited digestion. These functions help prepare an organism's body for the physical strain required to escape a potentially dangerous situation or to fend off a predator. Q: What system serves as the relay between the cns and the internal organs? Choices: - cellular nervous system - central nervous system - limbic nervous system - autonomic nervous system A:
Ans: autonomic nervous system
(Q).
Answer the following question given this paragraph: Molar mass is equal to density multiplied by molar volume. Q: Molar mass is equal to density multiplied by what? Choices: - molar energy - molar weight - molar gravity - molar volume A:
(A).
molar volume
Ques:Answer the following question given this paragraph: Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. Q: The measure of how much a given volume of matter decreases when placed under pressure is called? Choices: - elasticity - solubility - malleability - compressibility A:

Ans:compressibility
Ques: Answer the following question given this paragraph: Diamond is a network solid and consists of carbon atoms covalently bonded to one another in a repeating three-dimensional pattern. Each carbon atom makes four single covalent bonds in a tetrahedral geometry. Q: What is a network solid and consists of carbon atoms covalently bonded to one another in a repeating three-dimensional pattern? Choices: - a zirconium - a ruby - an agate - a diamond A:
Ans:
a diamond
