The crux of system thinking is what?
The crux of system thinking is interaction. System thinking is a language for describing and understanding the forces and interrelationships that shape the behavior of systems.
What is nh2conh2?
CO(NH2)2 is the chemical formula for the organic compound urea. Urea is generated by the excretory systems of animals.
Is chloride used in public water to kill bacteria?
Chlorine is a common chemical used to kill bacteria in U.S. public water systems.
How does the law of conservation of mass apply to a chemical reaction?
The law of conservation of mass states that matter is neither created nor destroyed in a chemical reaction (in a nuclear reaction it is a different matter). Therefore the total mass of the reactants equals the total mass of the products. This law is hard to grasp by some since some reactions are gas creating reactions, and most reactions occur in open systems; Therefore, the gas escapes and cannot be weighed properly, but mass is still conserved.
How iron bacterias like Leptothrix and Galeona can be eradicated successfully from the well water sources?
You will need to run the water through a proper chemical extraction iron filter to remove these. Such systems are common, but not cheap.
What is the importance of enzymes to biological systems?
Enzymes decrease the amount of activation energy required for chemical reactions to occur.
How are chemical reactions described?
Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
In nonliving systems chemical reactions can be sped up by adding?
The most common way to speed up chemical reactions in non-living systems is to add heat. Heat causes the molecules to move faster, creating more collisions. In some reactions, extra oxygen is used to speed them up.
What is the substance that changes the rate of chemical reactions without being changed called?
In biological systems an enzyme speeds up the reaction without changing it. In other chemical reactions this function is achieved by a catalyst.
What is the name of the substance that speeds up chemical reactions?
This substance is called catalyst; and in living systems it is an enzyme.
The reactions involving most chemical compounds in living systems depend upon the presence of?
Oxygen and/or water.
What breaks down large molecules?
Larger molecules become smaller molecules by chemical reactions referred to as decomposition reactions. These can be as simple as oxidation, or as complex as catalyzed reduction of hydrocarbons (oil). The chemical reactions can be triggered by other reactive chemicals, by catalysts, or by the addition of energy (heat, electric current). They can be spontaneous or be deliberate, and they can sometimes be self-sustaining, as in a cascade reaction.
A catalyst for chemical reactions in biology systems is a?
Biological catalysts are called enzymes. All enzymes are globular proteins, and speed up metabolic reactions in our bodies.
What compound regenerates oxygen?
There are several methods used to in the process of regeneration of OXYGEN. It depends upon the system you are asking the question. 1) Biological Living systems (Plants) - Photosynthesis 2) Chemical Inorganic Reactions 3) Chemical Organic Reactions
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
Agent that causes change in the activity of a structure?
systems
What Organic molecules that catalyze reactions in living systems are?
Enzymes are organic molecules that catalyze reactions in living systems.
