Question
Chapter 27.6, Problem 2MC
Summary Introduction
To determine:
The data that led the researchers conclude that whales cannot taste umami, sweet, bitter, or sour.
Concept introduction:
The taste genes of the whale are present in the cell membrane of the taste receptors cells. These cells contain the protein which is encoded by the taste genes. There are two types of taste genes present in the whales that are T1R (taste receptor type 1) an T2R (taste receptor type 2). The T1R encode for the umami, and sweet taste receptors, and T2R encodes for the bitter taste receptor.

If you can taste only five things (salt, bitter, sweet, sour, umami), why do the many foods you eat all seem so distinct?
We have five tastes related to the taste buds on our tongue: sweet, salty, umami, bitter and sour.Not all animals have the same tastes we do. Why do we have these particular five tastes? What does each one detect on a molecular level? What do you think the evolutionary advantage is for each? Finally, how has our environment changed to make some of these "tastes" change from an advantage to a disadvantage in an evolutionary sense.
Distinguish between static and dynamic equilibrium. The sense of equilibrium (balance) is really two senses— static equilibrium and dynamic equilibrium—that come from different sensory organs. The organs of static equilibrium (stat′ik e″kwı˘-lib′re-um) sense the position of the head, maintaining balance, stability and posture when the head and body are still. When the head and body suddenly move or rotate, the organs of dynamic equilibrium (di-nam′ik e″kwı˘- lib′re-um) detect such motion and aid in maintaining balance.
