What three substances are needed for bioluminescence to occur?
Luciferin, and enzyme called luciferase. Bioluminescence does not occur in the absence of oxygen.
What are the three uses of acids?
Acids can be used to determine the concentration of a given alkaline solution. Acids can be used to dissolve solids that do not dissolve in water. Abides are used to identify certain substances, such as in cation precipitation.
What determines wether a compound will dissolve in water?
To understand why things dissolve at all, we will look at the solution formation process from a thermodynamic point of view. shows a thermodynamic cycle that represents the formation of a solution from the isolated solute and solvent. From Hess's law we know that we can add the energies of each step in the cycle to determine the energy of the overall process. Therefore, the energy of solution formation, the enthalpy of solution, equals the sum of the three steps--ΔHsoln = ΔH1 + ΔH2 + ΔH3 truth is i dont have a clue......................
What is a solution composed of?
A solution is a mixture of two or more substances in the same physical state, especially where one substance is held in a different phase state within another. The substance which maintains its phase is the solvent, and the dissolved substance is the solute. the combination is a mixture because no chemical reactions occur between the substances. Gas phase solvents can only dissolve other gases. Liquid phase solvents can dissolve any of the three phases (solid, liquid, gas). Solids solvents can dissolve any of the three phases, but there are fewer instances in number (hydrogen or liquid mercury in metals, and alloys which are technically solutions). The solution form can have a different melting / freezing point than the separate elements or compounds.
What are three general reasons to study chemistry?
Three general reasons to study chemistry are: 1. It is a part of everyday life. 2. It helps you understand the mechanism of everything that is going around you. 3. It tells you how reactions occur and bonds are formed, new substances are formed at the microscopic level. Chemistry is the study of the composition, structure, properties and change of matter.

What are the three parts of a cell and what there jobs are?
the 3 parts of a cell are : 1 Nucleus- this controls what happens inside the cell . 2 Cell Membrane - this controls what substances enter and leave the cell 3 Cytoplasm - this is where the chemial processes occur
What are the three processes that occur during chemical weathering?
ice, wind, and water when they start to move things

What are three functional proteins?
control the rate of reactions and regulate cell processes. forms bones and muscles. transport substances in/out of cells or to help fight disease.
What is an alternative to salt sand and iron filings IN separating experiment?
You need, basically:Something that will dissolve in waterSomething that will not dissolve in water and is not attracted to a magnetSomething that will not dissolve in water and is strongly attracted to a magnetAny three substances that fit those criteria will work. However, the three you listed are probably the easiest to find.You COULD base the second separation on "won't dissolve but will/won't float on water" instead of on magnetism, or on "won't dissolve but melt at very different temperatures". Again, probably more difficult that the listed example.
Are three substances that the excretory system removes from the body?
Three substances are water, nitrogen, and access salts.

What process is a method of heat transfer but it does not contribute to the moving heat energy in and around the earth?
There are three means of heat transfer, Convection, conduction, and radiation. All three occur to some degree in all heat transfer processes.

How can you separate something that can dissolve?
You can remove dissolved substances in three ways: 1) A semipermeable membrane 2) boiling off the solvent (or in the case of water, freezing it) 3) adding another solute that will cause the dissolved substance to precipitate from solution
