Answer the following question given this paragraph: Condensation reactions are the chemical processes by which large organic compounds are synthesized from their monomeric units. Hydrolysis reactions are the reverse process. During condensation reactions, water is produced from the two molecules being bonded together; an H from one monomer is joined to an -OH from another molecule, producing H 2 O. Q: What is produced during a condensation reaction? Choices: - rain - wind - fire - water A:
water

Answer the following question given this paragraph: Not getting enough minerals can cause health problems. For example, not getting enough calcium may cause osteoporosis. This is a disease in which the bones become porous so they break easily. Getting too much of some minerals can also cause health problems. Many people get too much sodium. Sodium is added to most packaged foods. People often add more sodium to their food by using table salt. Too much sodium has been linked to high blood pressure in some people. Q: Not getting enough calcium may cause what health problem? Choices: - blindness - arthritis - diabetes - osteoporosis A:
(Answer)
osteoporosis

Choices: - plasma - fluorescence - effervescence - luminescence A:
Ans: luminescence

Ans:circulatory
Ques: Answer the following question given this paragraph: 6.2 Potential, Kinetic, Free, and Activation Energy Energy comes in many different forms. Objects in motion do physical work, and kinetic energy is the energy of objects in motion. Objects that are not in motion may have the potential to do work, and thus, have potential energy. Molecules also have potential energy because the breaking of molecular bonds has the potential to release energy. Living cells depend on the harvesting of potential energy from molecular bonds to perform work. Free energy is a measure of energy that is available to do work. The free energy of a system changes during energy transfers such as chemical reactions, and this change is referred to as G. The G of a reaction can be negative or positive, meaning that the reaction releases energy or consumes energy, respectively. A reaction with a negative G that gives off energy is called an exergonic reaction. One with a positive G that requires energy input is called an endergonic reaction. Exergonic reactions are said to be spontaneous, because their products have less energy than their reactants. The products of endergonic reactions have a higher energy state than the reactants, and so these are nonspontaneous reactions. However, all reactions (including spontaneous -G reactions) require an initial input of energy in order to reach the transition state, at which they'll proceed. This initial input of energy is called the activation energy. Q: What kind of energy is specifically defined as the energy that is available to do work? Choices: - used - new - old - free A:
Ans:
free
