Answer the following question given this paragraph: Note the Pattern Pi bonds between carbon and the heavier chalcogenides are weak due to poor orbital overlap. Binary compounds of carbon with less electronegative elements are called carbides. The chemical and physical properties of carbides depend strongly on the identity of the second element, resulting in three general classes: ionic carbides, interstitial carbides, and covalent carbides. The reaction of carbon at high. Q: Binary compounds of carbon with less electronegative elements are called what? Choices: - alkaloids - oxides - carborane - carbides A:
carbides

Answer the following question given this paragraph: Q: Which stage of development is a period during which apoptosis is widespread and plays a crucial role? Choices: - puberty - transgenic - infancy - embryonic A:
(Answer)
embryonic
Ques: Answer the following question given this paragraph: Reactions can proceed by themselves if they are exergonic or exothermic, that is if they release energy. The associated free energy of the reaction is composed of two different thermodynamic quantities, enthalpy and entropy. Enthalpy is a measure of the total energy of a thermodynamic system. The change in enthalpy is positive in endothermic reactions, and negative in exothermic processes. Q: Enthalpy is a measure of the total energy of what kind of system? Choices: - macroscopic - planetary - hypodermic - thermodynamic A:
Ans: thermodynamic
(Q).
Answer the following question given this paragraph: The atmosphere has layers. The layers correspond with how temperature changes with altitude. By understanding the way temperature changes with altitude, we can learn a lot about how the atmosphere works. Q: The layers of the atmosphere correspond with what changes with altitude? Choices: - friction - nitrogen - oxygen - temperature A:
(A).
temperature
Ques:Answer the following question given this paragraph: Lipids are biochemical compounds such as fats and oils. Organisms use lipids to store energy. In addition to carbon and hydrogen, lipids contain oxygen. Q: Lipids are biochemical compounds such as fats and? Choices: - vegetables - salts - minerals - oils A:

Ans:oils
Question: Answer the following question given this paragraph: Mars is the easiest planet to observe. As a result, it has been studied more than any other planet besides Earth. People can stand on Earth and observe the planet through a telescope. We have also sent many space probes to Mars. In April 2011, there were three scientific satellites in orbit around Mars. The rover, Opportunity, was still moving around on the surface. No humans have ever set foot on Mars. NASA and the European Space Agency have plans to send people to Mars. The goal is to do it sometime between 2030 and 2040. The expense and danger of these missions are phenomenal. Q: Which other planet in the solar system is the easiest to observe from earth? Choices: - Pluto - Mercury - Jupiter - mars A:
Answer:
mars
