Unlike bony fish in the sea, cartilaginous fish are hypertonic in their osmotic pressure. Thus: O a. They have high levels of sodium chloride in their cells compared with a bony fish. O b. They produce very little urine. Oc They have high levels of urea in their blood. O d. Osmoregulation requires a greater expenditure in energy compared with a bony fish. O e. They need much larger salt glands than in a bony fish.

The circulatory system of aquatic arthropods is more efficient. C. Gas exchange across the body surface occurs more readily in aquatic environments. D. Buoyancy of the water can support heavier exoskeletons.
Animals that exhibit endothermy usually: Group of answer choices A. can consume less food per unit of body mass than ectotherms, for survival. B. can be active across a wider range of environmental temperatures than ectotherms. C. spend a greater proportion of their energy budget than ectotherms on growth and reproduction. D. A and B E. A, B, and C
A. List some invertebrates who are endotherms B. How can something be ectothermic but also maintain homeothermy? C. What are some ways that ectotherms (so called cold blooded) animals can adjust their temps behaviorally?
Gas bladders make up an average of 5 percent of body volume in marine fish and 7 percent of body volume (on average) in freshwater fish. What is the reason for this difference? freshwater fish have a larger average body size than salt water fish it is more difficult to produce lift swimming in freshwater than swimming in saltwater freshwater fish need to have a lower overall body density in order to remain neutrally boyant freshwater fish need to have a higher overall body density in order to remain neutrally boyant
You are studying a large tropical reptile that has a high and relatively stable body temperature. How do you determine whether this animal is an endotherm or an ectotherm? (A) You know from its high and stable body temperature that it must be an endotherm. (B) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. (C) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. (D) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm.
The migratory eel, Anguilla rostrata, is born and lives the juvenile (immature) part of its life in a freshwater environment, but then migrates thousands of miles through the ocean as an adult in order to breed. These eels are known to regulate their internal water and salt balance. What adaptations would you expect this eel to have in order to transition from fresh water to salt water at these two life stages The adult eels would be better at removing salt from their bodies compared to juveniles. The adult eels would spend energy keeping salt in their bodies. The juvenile eels would spend energy keeping water in their bodies. The juvenile eels would be better at removing salt from their bodies compared to adults. please help
(1) Please examine the figure below, depicting a portion of the rete mirabile associated with the gas bladder of two fishes: (a) One of these diagrams references a shallow water fish and the other references a deep water fish. Which diagram belongs to which type of fish? How can you tell? (b) Many deep water fish lack swim bladders altogether! Why do you think this is? What does the presence of a swim bladder in the above deep sea fish suggest about its behavior?
Identiffy the organs involved: A. terminal opening for digestive wastes- common to both toad and cockroach B. hair-like excretory organ- unique to the cockroach. C. Longitudinal pumping vessel that runs mid-dorsal through the thorax and abdomen:- common to both toad and cockroach D. slit-like opening that eventually leads to the posterior respiratory tract- unique to toad E. ventral-longitudinal pair of nerves behind fat tissues: unique to toad
Research the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation? Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions: ectotherm in cool conditions ectotherm in hot conditions Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.
which type of animals consumes little or no energy in maintaining water balance? a. birds b. mammals c. marine vegetables d. marine invertebrates
Elephant seals do deep dives to forage for food. The energy used by the seals in diving depends on their body composition; for example, fatter seals use less energy to swim to the surface at the end of a dive, allowing them to takelonger, more productive dives. Explain why you’d expect this to be the case.
