Question
Chapter 40.4, Problem 3CC
Summary Introduction
To explain: The changes in the metabolic rate in an alligator and a lion resting in a zoo, when at night the air temperature lowers down.
Concept introduction:
Thermoregulation is an ability of an organism to maintain its body temperature. Animals are categorized into two types based on their thermoregulation mode: ectotherms and endotherms. Ectotherms are animals that get warmed by external sources, whereas endotherms maintain their body temperature based on internal

Can I get this rewritten
While the surface area of an organism scales as a square of the length (L^2) and the volume of an organism increases as the cube of the length (V^3), basal metabolic rate is not affected by the ratio of surface area to length of an organism.This can be seen in the data extracted from the ADW Quardvaark database as well which showed that mammals had an R^2 value of 0.7258 when looking at their length and basal metabolic rate and an R^2 value of 0.0074 when looking at the length of mammals and their length-specific basal metabolic rate. Birds had an R^2 value of 0.1678 when looking at their length and basal metabolic rate and an R^2 value of 0.0021 when looking at the length and length-specific basal metabolic rate of birds.

- one anotn The hypothesis is that since the basal metabolic rate of birds and mammals differ from one another based on their mass then the length of mammals and birds will also influence the change in their basal metabolic rate.arrow_forwardHibernating bears lose up to 30% of their body mass over the winter. Where does that body mass go? It is converted to CO₂ and H₂O in cellular respiration and then excreted from the bear's body. It is converted to heat and then lost to the environment. It is converted to ATP molecules then used to power cellular reactions.arrow_forwardWhich of the following is true regarding the metabolism in animals? O Metabolism is the total chemical activity, which is the sum of all anabolic and catabolic processes. O The Anabolic Pathways serve to break down molecules while the Catabolic Pathways synthesize important chemical building blocks. Through respiration, organisms obtain oxygen, whose rate is inversely porportional with the metabolic rate. O Metabolic Rate is not influenced by an organism's body temperature. O Poikilotherm organisms do not have any effect in body temerature when their enviornment temperature changes.arrow_forward

Under cold conditions, more body heat becomes lost to the environment. Endothermic ani- mals rely on different mechanisms that allow them to maintain their body heat. Which of the following mechanisms that occur in endothermic animals does not describe a mechanism by which they maintain their body heat under these types of conditions? A B с D Some endothermic animals hibernate during extreme environmental conditions, which decreases the rate of metabolic reaction and decreases heat loss. The tissues of the blood vessels of many endothermic animals can dilate and move closer to the skin, allowing for heat to move more readily into the environment. Shivering, which can occur involuntarily in most endothermic animals, produces rapid muscle contractions, which increase the rate of cellular respiration and thereby increase heat production.

To test the effect of light on the survival of Daphnia, the 6 beakers were divided equally into 2 treatments: light & dark. Beakers assigned to the dark treatment were covered w/ aluminum foil.3. One zebrafish (about 2-3 cm) starved for 24 hours was placed in each beaker.4. Fifty (50) Daphnia sp. individuals were added in each beaker containing the starved zebrafish. The top of the beakers assigned to the dark treatment were covered with aluminum foil.5. One hour after, the zebra fish was scooped out & the no. of surviving Daphnia in each set-up were counted. How did light exposure affect the survival of Daphnia when exposed to a predator? Are the results consistent with your expectations? Relate this to your hypothesis & explain. answer.arrow_forward
