Chapter 33, Problem 27RQ
Which of the following is not true about acclimatization?
- Acclimatization allows animals to compensate for changes in their environment
- Acclimatization improves function in a new environment
- Acclimatization occurs when an animal tries to reestablish a homeostatic set point

Animals must maintain temperature and water balance. The state of maintaining a constant or regular internal environment is called:
an adaptation.
homeostasis.
a trade-off.
acclimitization.
Which of the following would help increase an endotherm's body temperature?
Select ALL that apply.
shivering
blood vessels narrowing
sweating
blood vessels widening
Read the following scenario and determine the parts of the homeostasis feedback loop.
When a human increases physical activity, the amount of fuel burned in its cells also increases, which in turn increases the concentration of dissolved CO2 in the blood. The CO2 reacts with water in the blood to make a weak acid, which lowers the pH of the blood. Sensory cells in the aortic arch register this drop in pH and send sensory information to the medulla oblongata of the brain. The medulla oblongata sends signals to the diaphragm to increase respiration. This will clear the CO2 from the bloodstream.
A. Name the stimulus in this scenario.
B. Explain what a receptor is in the homeostasis feedback loop and name the receptor in this scenario.
C. Explain what an integrating center is in the homeostasis feedback loop and name integrating center in this scenario.
D. Explain what an effector is in the homeostasis feedback loop and name the effector in this scenario.
E. Name the response in this…

- Riding a bicycle requires additional energy from leg muscles. Which of the following conditions may result from this activity, and which response helps restore the body to its normal condition? * decreased oxygen can be replaced by digesting an apple. increased carbon dioxide in the blood can be removed by breathing faster. increased sugars in the bloodstream can be diluted by drinking water. increased salt wastes can be removed by the heart. No answerarrow_forwardWhich of the following is an example of a positive feedback loop? Regulation of Calcium levels in the blood Regulation of water balance Regulation of blood sugar Regulation of blood clottingarrow_forwardWhat is the trade-off of ectotherms with regard to maintaining an internal environment that doesn’t vary much? Ectotherms are larger than endotherms because they need to have a larger surface area to volume ratio in order to either increase or lower their temperature. Ectotherms usually have fur in order to conserve heat when they live in very cold environments. Ectotherms are smaller than endotherms because they need more surface area to dissipate heat relative to their insides. Ectotherms can survive in a wider variety of habitats because they are smaller and can behaviorally adapt to a wide variety of temperatures.arrow_forward
- Which of the following examples DOES NOT involve negative feedback regulation? Regulation of blood clotting Regulation of calcium concentration Regulation of electrolyte concentration Regulation of blood glucose concentrationarrow_forwardWhich of the following statements is True?a. Ectotherms generate most of their body heatmetabolically.b. Ectotherms include birds and mammals.c. Ectotherms experience variable body temperatures.d. Ectotherms are known as “warm-blooded” animals.arrow_forwardWhich of the following statements is incorrect? a) Acclimatization involves genetic change. b) Adaptations emerge over many, many generations. c) Tanning is an example of acclimatization. d) Adaptation is inherited, acclimatization is notarrow_forward
- Which of these is a difference between Acclimation and Adaptation in most instances? (select all that are correct) Question 3 options: An individual can not adapt None of these are correct Acclimation is phenotypic while adaptation is genetic Acclimation is reversible but adaptation is not Adaptation takes much longer than acclimationarrow_forwardWhich of the following is an example of negative feedback? A. High blood sugar will increase the viscosity of blood plasma (plasma is concentrated). In response, water is drawn into the plasma from surrounding tissues in order to dilute the plasma B. Breathing rate increases during exercise to provide more oxygen to muscle cells. Heart rate also increase to increase the speed at which the oxygen is delivered. C. During digestion cells in the stomach produce HCl to begin breaking down proteins, the HCl then stimulates the release of pepsin, to continue breaking down proteins. D. In the immune system, antibodies produced by B-cells bind to antigens, which activates other B-cells to produce antibodies of the same kind.arrow_forwardDuring intense exercises and when muscles are working harder, our cells metabolize glucose rapidly resulting to oxygen molecules being quickly consumed. Which of the following becomes the human body's coping mechanism in response to limited oxygen supply? faster breathing and lower blood circulation slower breathing and faster blood circulation faster breathing and faster blood circulation slower breathing and slower blood circulationarrow_forward
