Mastering Biology Test 1 Quiz

water's high heat of vaporizationEvaporative cooling takes place when molecules with the greatest kinetic energy leave a fluid as gas molecules. Because of water's high heat of vaporization, a large amount of heat must be absorbed for 1 gram of water to be converted from liquid to gas. The dog loses this heat as the water on its tongue evaporates, allowing him to cool down by panting. To understand why this answer is correct, read about evaporative cooling.

Starch and cellulose differ in the glycosidic linkages between their glucose monomers.Both starch and cellulose are glucose polymers, but the glycosidic linkages in these two polymers differ. Glucose can have two slightly different ring structures. When glucose forms a ring, the hydroxyl group attached to the number 1 carbon is positioned either below (alpha) or above (beta) the plane of the ring. In starch, all the glucose monomers are in the alpha configuration. In cellulose, all the glucose monomers are in the beta configuration. As a result, every other glucose monomer is "upside down" with respect to its neighbors. The differing glycosidic linkages in starch and cellulose give the two molecules distinct three-dimensional shapes, leading to key functional differences.

Metabolic cooperation between prokaryotic cells forms a biofilm that allows bacterial colonies to transport nutrients and wastes. Biofilms may damage industrial equipment or cause tooth decay.This emergent property emerges at the community level, due to the interactions among prokaryotic species forming the biofilm. Read about levels of biological organization in and emergent properties.

The H+ concentration of lemon juice is higher than the H+ concentration of household bleach by a factor of 1011 (100 billion).The figure shows the pH scale and pH values of some aqueous solutions, including lemon juice and household bleach. The pH of a solution is the negative logarithm of H+ concentration.

It is possible to test hypotheses, such as those involving historical events, without conducting experiments.Although it is not possible to carry out experiments to test hypotheses about evolutionary relationships between living groups or about the timing of the origin of major evolutionary innovations, such hypotheses can be evaluated by making predictions about the expected findings that would result from these hypotheses. Data can then be collected to test whether these predictions are correct. Read about the forms of scientific inquiry and the scientific method.

Weak bonds are transient and easily reversible. Molecules that form weak bonds can come together, interact, and then separate. The combined effect of many weak and transient hydrogen bonds or Van der Waals interactions can produce important emergent properties. Read about the importance of the transience of weak bonds such as hydrogen bonds, ionic bonds, and Van der Waals interactions.

Van der Waals interactions can form between atoms of equal electronegativity.Even nonpolar covalent bonds have temporary regions of partial positive and negative charge, due to the chance movements of electrons. Attractions between such transient positive and negative charges create weak Van der Waals interactions.
