Water Works
This describes a molecule with an unequal distribution of charge.
What is polar?
Water molecules sticking to other water molecules demonstrate this property.
What is cohesion?
In salt water, water does the dissolving, making it this part of the solution.
What is the solvent?
Amino acids are the monomers that build this macromolecule.
What are proteins?
Anything that takes up space and has mass is called this, while the smallest part of an element that helps make up all living things, is called this.
What are matter and atom?
A substance dissolves in water. Water is present in the greater amount and does the dissolving. Name (1) what water is called, (2) what the dissolved substance is called, (3) what the entire mixture is called, and (4) The special name for the mixture because water is the solvent.
What are solvent, solute, solution, and aqueous solution?
This describes a substance that is water loving.
What is hydrophilic?
Water sticking to a different type of substance demonstrates this property.
What is adhesion?
In salt water, the sale is being dissolved, making it this.
What is the solute?
Monosaccharides join together to form this type of macromolecule.
Oils are examples of this macromolecule, which helps create the phospholipid bilayer.
What are lipids?
A drop of water beads up on a leaf instead of spreading apart. The water molecules are attracted to each other, creating a tight surface. Name the attraction between the water molecules and the surface effect it produces.
What are cohesion and surface tension?
Oil does not mix with water because water has this property.
What is hydrophobic?
A water droplet beads up because water molecules are attracted to one another.
What is cohesion?
When a solute and solvent are mixed together, the result is called this.
What is solution?
Fatty acids are associated with this macromolecule, which provides 9 kcal per gram.
What are lipids?
Name the 3 forms of matter listed on your study guide.
What are solid, liquid and gas?
A lake freezes during winter, but the ice remains on top while liquid water stays underneath. Name the property that causes the ice to float and explain why this is important to organisms living in the lake.
What is ice being less dense than liquid water, allowing aquatic life to survive in the liquid water below.
What is high heat capacity?
Water clinging to the inside of a glass demonstrates this property.
What is adhesion?
When water is specifically the solvent, the mixture has this name.
What is an aqueous solution?
Nucleotides are the monomers of this macromolecule found in DNA and RNA.
What are nucleic acids?
DNA and RNA belong to this macromolecule. Its five bases listed on your study guide are adenine, thymine, guanine, cytosine and urasil.
What are nucleic acids?
A food contains a macromolecule made from monosaccharides. The body breaks it down for energy, and each gram provides 4 kcal. Identify the macromolecule, its monomer, and its polymer.
What are carbohydrates, monosaccharides and polysaccharides?
Ice stays at the top of a lake instead of sinking because solid water has this property compared with liquid water.
What is lower density?
An insect can appear to stand on water because cohesion creates this effect at the water's surface.
What is surface tension?
Water can dissolve many different substances, which is why it is commonly called this.
What is universal solvent?
Match all 4 macromolecules to their polymer: protein, lipid, carbohydrate and nucleic acid.
What are polypeptides, triglycerides, polysaccharides, and nucleic acids?
Meat and dairy are examples of this macromolecule, which performs many different jobs in the body.
What are proteins?
A substance is made of fatty acids, provides more energy per gram than proteins or carbohydrates, and helps form the phospholipid bilayer of cells. Identify the macromolecule, its polymer, and the number of kcal it provides per gram.
What are lipids, triglycerides, and 9 kcal per gram?
A molecule with an equal distribution of charge is described as this.
What is nonpolar?
"Cohesion involves these types of molecules sticking together, while adhesion involves these types of molecules sticking together."
What are like molecules for cohesion and unlike molecules for adhesion?
A substance that is attracted to water is described as this; one that avoids water is described as this.
What are hydrophilic and hydrophobic?
This is the small building block that joins with others to make a larger molecule.
What is a monomer?
This form of matter has a definite shape and definite volume.
What is a solid?
Salt dissolves in water. Identify the solute, solvent, type of mixture, special name for a solution containing water, AND explain why water can dissolve so many substances.
What are salt=solute, water=solvent, solution, aqueous solution, and water is polar and is known as the universal solvent?
A polar molecule has this type of charge distribution, while a nonpolar molecule has this type.
What are unequal and equal charge distributions?
Water molecules sticking to other water molecules is this property; water sticking to a different substance is this property.
What are cohesion and adhesion?
In sugar water, identify the solute, the solvent, and the entire mixture.
What are sugar, water and solution?
This is a large molecule made by joining repeating smaller building blocks together.
What is a polymer?
Once of these states has a definite volume but takes the shape of its container; the other has neither a definite shape nor definite volume. Name both.
What are liquid and gas?
Water's high heat capacity is important to living things because it helps the body do this.
What is regulate temperature?
This "skin like" effect at the surface of water is caused by cohesion between water molecules.
What is surface tension?
What is called this because it can dissolve many different substances?
What is the universal solvent?
Protein and carbohydrates provide this many kcal per gram, lipids provide this many, and nucleic acids provide this many.
What are 4,4,9, and o kcal per gram?
When water freezes, it becomes a less dense solid. What happens as a result, and why is this important for life in the ocean?
What is ice floats, allowing liquid water and aquatic life to remain below it?
