Summary Introduction
To review:
The inference drawn by scientists after observing a defective gene in the feline family that is used to identify the sweet taste.
Introduction:
Vertebrates have chemoreceptors that are located in the mouth. These chemoreceptors are present in the form of taste buds. Different types of taste buds are able to detect different types of tastes. About 10,000 taste buds are present in the mouth, throat, and upper roof of the mouth in human beings. In some animals like cats, certain genes that encode for particular taste receptors are missing.

- How do whales and dolphins get oxygen at night?A. They absorb oxygen from the water.B. They sleep in just one hemisphere at a time.C.

- When researchers first discovered that airflow through a bird’s paleopulmonal parabronchi is unidirectional, the question arose as to whether gas exchange is countercurrent, cocurrent, or cross- current. Some ingenious investigators carried out experiments in which they measured the efficiency of gas exchange between air and blood in duck lungs when parabronchial airflow was in its normal direction and when the direction of parabronchial airflow was artificially reversed. The efficiency did not change. How is this evidence against countercurrent and cocurrent gas exchange? How is this evidence for cross-current exchange?arrow_forwardCan you answer all the parts to this question regarding fish A: Describe countercurrent exchange in your own words. B: Describe concurrent exchange in your own words. C: Mammals have dead end sacs called “alveoli” and don’t have the super efficient countercurrent exchange system seen in fish. Why do you think countercurrent exchange is necessary for fish? (hint: think about the difference between where most mammals and fish live).arrow_forwardEVOLUTION LINK Aquatic mammals such as whales and dolphins use lungs rather than gills for gas exchange.

Explain why only fish that evolved to live in cold waters, like the crocodile icefish, could lose hemoglobin? ( unlike terrestrial organisms, marine organisms like fish use oxygen dissolved in water.)arrow_forwardYou are studying with a friend who is describing the Bohr effect. She tells you that in the lungs, hemoglobin binds oxygen and releases hydrogen ion; as a result, the pH increases. She goes on to say that in actively metabolizing muscle tissue, hemoglobin releases oxygen and binds hydrogen ion and, as a result, the pH decreases. Do you agree with her reasoning? Why or why not?arrow_forward
- All mammals breathe through the lungs, as with mammals that live in the sea such as whales. How does the whale breathe in water?arrow_forwardWhy does altitude have almost no effect on an animal’s ability to rid itself of CO2 through gas exchange?arrow_forwardAs discussed in the Biology and Society section, the delivery of oxygen to muscles is the limiting factor for many athletes. Some athletes seek to improve their athletic performance through blood doping, which can artificially increase athletic capacity. Other athletes achieve the same result by training at high altitude (which promotes the formation of more red blood cells by the bone marrow). If two athletes achieve exactly the same result—one due to injecting her own blood and one due to training at altitude—why do you think the former is considered cheating but the latter is not? What would you do to enforce antidoping rules in sports at all levels (high school, college, Olympic, professional)?arrow_forward
