Three substances needed for bioluminescence are luciferase (enzyme), luciferin (substrate), and oxygen. When luciferin reacts with oxygen in the presence of luciferase, light is emitted.
To separate three substances in the past tense, you would write: "I separated three substances."
The three types of solubility are: soluble (able to dissolve in a solvent), insoluble (unable to dissolve in a solvent), and partially soluble (able to dissolve only to a limited extent in a solvent).
Covalent-network substances have strong covalent bonds that hold their atoms together in a three-dimensional network structure. This network structure makes it difficult for common solvents to break the bonds and dissolve the substance, leading to their insolubility in most solvents.
The polar or nonpolar nature of the compound's molecules primarily determines whether a compound will dissolve in water. Compounds that are polar, like salts and sugars, tend to dissolve in water due to the ability of water molecules to surround and interact with their charged or polar groups. Nonpolar compounds, such as oils and fats, do not dissolve in water because water molecules cannot effectively interact with their nonpolar structures.
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

ice, wind, and water when they start to move things
Three physiological processes involved in absorption are diffusion, active transport, and facilitated diffusion. Diffusion is the movement of substances from an area of high concentration to an area of low concentration. Active transport requires energy to move substances against their concentration gradient. Facilitated diffusion involves the use of carrier proteins to help substances move across a cell membrane.
Three substances that can generate electrical energy are coal, natural gas, and uranium. These substances can be used in power plants to produce electricity through various processes such as combustion or nuclear fission.
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.
Salt, sugar, and baking soda are examples of solids that dissolve in water. When these substances are mixed with water, they break down into molecules or ions and disperse throughout the water, forming a homogeneous solution.
control the rate of reactions and regulate cell processes. forms bones and muscles. transport substances in/out of cells or to help fight disease.
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
To separate three substances in the past tense, you would write: "I separated three substances."

The liver, kidneys, and lungs are the three main organs that help eliminate toxic substances from the body. The liver processes toxins to make them easier for the body to remove, the kidneys filter toxins from the blood and eliminate them through urine, and the lungs expel toxins through respiration.
