length of the loop of Henle in animals living in dry environments is different from the length in those living in environments where water is abundant

"Fresh water animals are unable to survive for long in sea water. Give reason."

Which of the following is a trade-off that comes from using endothermy?     Lower possible stamina     Lower possible speed     Increased energetic cost     Decreased foraging opportunities

The Eastern Quoll, pictured below, is a native marsupial found in Tasmania. It is nocturnal and hunts at night for the small mammals and insects that it eats. Temperatures in its habitat range from 3 degrees Celsius in winter to 23 degrees Celsius in summer. Question 6.a. Based on the picture above, name one feature that would assist the quoll in thermoregulation. how this feature would assist in thermoregulation.

Thorns on a rose are an example of an adaptation to increase survival. How do the thorns help the rose to survive?         The thorns help insects crawl to the flower.         The thorns collect and store water to aide in the survival of the rose.         The thorns are appealing to insects, causing them to be attracted to the rose. The rose then uses the insects for nourishment.          The thorns serve as protection for the roses. Animals and insects avoid the roses because the thorns can cause harm.

Which is a response to higher temps in a habitat?  More movement, thicker fur, more fat storage, more sweating Which one is it?

Different types of potatoes have varying natural sugar concentrations. Explain how this may influence the water potential of each type of potato.

Vertebrates became successful in relatively dry environments due to what characteristic? the ability to maintain a constant body temperature the shelled, amniotic egg a four-chambered heart two pairs of appendages

Imagine a chemical spills into a lake. At levels of 10 part per 1000, this chemical causes reduced fertility in Rainbow Trout (a type of fish), and at 20 parts in 1000 it is lethal to Rainbow Trout. It is not toxic for fish in water at the concentration present at the time of the spill, but it will biomagnify in the invertebrate prey that trout feed on. The table below shows the concentration of the chemical in the invertebrates in the years after the spill. Year after spill Chemical concentration in invertebrates (parts per 1000) 0 1 2 1 5 7 10 18 20 21 3 4 5 6 Based on this information, answer the following questions. a. In what year following the spill will the birth rate of trout decrease? b. In what year will the mortality rate of the trout increase? C.

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
