Water Gets Weird
Researchers compare two liquids of equal mass. Liquid X requires substantially more energy than Liquid Y to increase by 5°C. Liquid X most likely forms more of these intermolecular attractions.
This reaction joins smaller molecules by removing the equivalent of one water molecule.
What is dehydration synthesis?
These simple sugars serve as the monomers used to construct polysaccharides.
What are monosaccharides?
What is a protein?
What is 100° C?
Two animals produce equal quantities of sweat. Animal A's sweat evaporates rapidly. Animal B's sweat remains on its skin. Assuming identical environmental conditions, this animal loses more thermal energy.
What is Animal A?
This reaction uses water to break a covalent bond between monomers.
What is hydrolysis?
A fatty acid containing no carbon-carbon double bonds is called this:
What is a saturated acid?
This unknown biological molecule has large nonpolar regions, causing it to interact poorly with water.
What is a lipid?
This is the freezing point of water in degrees Celsius.
What is 0° C?
Because oxygen attracts shared electrons more strongly than hydrogen, a water molecule has this overall property.
What is polarity?
During hydrolysis, the H from water is added to one monomer while this portion of water is added to the other.
What is the hydroxyl group, OH?
Adding carbon-carbon double bonds to a fatty acid generally causes the chain to do this:
What is bend or form a kink?
This unknown polymer has repeating sugar phosphate backbone with nitrogenous bases extending from the backbone.
What is a nucleic acid?
With an atomic number of 6, this element forms the backbone of biological molecules.
What is carbon?
A water strider can remain on the water's surface largely because hydrogen bonding produces this property.
What is surface tension?
Ten monomers are joined into one linear polymer by dehydration synthesis. Assuming only these monomers are involved, this many water molecules are released.
What is 9?
A molecule has a polar region and nonpolar fatty acid regions and spontaneously forms a bilayer in water. Identify the molecule.
What is a phospholipid?
Which macromolecule is polar and attracts water, allowing desert rodents to get water from stored seeds?
What is a carbohydrate?
Carbon can form a maximum of this many covalent bonds.
What is four?
Water molecules climbing a narrow plant vessel stick to one another and to the vessel wall. When water evaporates off the leaf, water moves up the vessels. Name this phenomenon.
Transpiration
A digestive enzyme causes a polymer to become several smaller molecules while water molecules are consumed by the organism. Identify the type of reaction.
Hydrolysis
Two cells contain fatty acids of equal length. Cell A’s fatty acids are mostly saturated, while Cell B’s are mostly unsaturated. When the temperature drops, this cell’s lipids are more likely to remain fluid.
What is Cell B?
Which carbohydrate is found in plant cell walls? It is also called 'fiber'.
What is cellulose?
Approximately this percentage of Earth's surface is covered by water.
