QuestionAnswer
Living things are composed mostly of [...]. Living things are composed mostly of water.
Every cell of a living thing is like a [...]-filled factory, providing the perfect medium for all life processes to take place. Every cell of a living thing is like a water-filled factory, providing the perfect medium for all life processes to take place.
materials in living things are circulated and transported by [...]-based fluids. materials in living things are circulated and transported by water-based fluids.
Water is a [...] molecule; that means it has a partially negative end and a partially positive end. Water is a polar molecule; that means it has a partially negative end and a partially positive end.
Water molecules are attracted to each other through what we call [...] 'bonds'; areas where the partially positive hydrogens of one molecule are attracted to the partially negative parts of another molecule. Water molecules are attracted to each other through what we call hydrogen 'bonds'; areas where the partially positive hydrogens of one molecule are attracted to the partially negative parts of another molecule.
[...] 'bonds' are NOT covalent or ionic bonds... They aren't actually bonds at all; the name is misleading. Hydrogen 'bonds' are NOT covalent or ionic bonds... They aren't actually bonds at all; the name is misleading.
[...] = (Co- ; together + hesion; sticking) Sticking together Cohesion = (Co- ; together + hesion; sticking) Sticking together
[...] = (Ad -; to + hesion; sticking) sticking to something else. Adhesion = (Ad -; to + hesion; sticking) sticking to something else.
[-sion] = sticking together [-sion] = sticking to something else Cohesion = sticking together Adhesion = sticking to something else
The hydrogen 'bonds' that water forms cause water molecules to stick to each other... this is called [-sion] The hydrogen 'bonds' that water forms cause water molecules to stick to each other... this is called cohesion
The hydrogen 'bonds' that water forms cause water molecules to stick to other polar molecules... this is called [-sion] The hydrogen 'bonds' that water forms cause water molecules to stick to other polar molecules... this is called adhesion
The surface tension that allows bugs to walk on top of water is created by the cohesion formed from [...] between water molecules. The surface tension that allows bugs to walk on top of water is created by the cohesion formed from hydrogen 'bonds' between water molecules.
A [...] is a material that causes another to dissolve within it to make a solution. The dissolved material is called a [...] . A solvent is a material that causes another to dissolve within it to make a solution. The dissolved material is called a solute .
Aqueous = within [...] (aqua) Aqueous = within water (aqua)
An [-ous] environment is any environment within water (aqua). An aqueous environment is any environment within water (aqua).
Water does NOT dissolve non-[...] substances such as oils and lipids. Water does NOT dissolve non-polar substances such as oils and lipids.
A plant cell stores excess water in a structure called a central [...] (little-cavity), which releases water as needed. A plant cell stores excess water in a structure called a central vacuole (little-cavity), which releases water as needed.
The desert-dwelling kangaroo rat can go [-s] without drinking water; it reabsorbs water from its own organs and extracts water from the foods it eats. The desert-dwelling kangaroo rat can go months without drinking water; it reabsorbs water from its own organs and extracts water from the foods it eats.
