Question

Most land-dwelling invertebrates and all of the amphibians _____. _____ Select one: a. are ectothermic organisms with variable body temperatures b. alter their metabolic rates to maintain a constant body temperature of 37°C c. have a net loss of heat across a moist body surface, even in direct sun d. are endotherms but become thermoconformers when they are in water e. become more active when environmental temperatures drop below 15°C

Answer 1

Answer:

A.)are ectothermic organisms with variable body temperatures.

Explanation:

Invertebrates animal are animals that lack a backbone, Land invertebrates include insects,spiders, centipedes ,coelenterate, an arthropod, mollusc and the rest.

Ectotherms are also called called cold-blooded animal because their bl body temperature regulation is dependendent on external sources, such as sunlight or a heated rock surface. Some of the examples of ectotherms are fishes, amphibians, invertebratesand reptiles. The aquatic ectotherms body temperature is usually compare closely to the temperature of the surrounding water

Ectothermic species that lives in temperate regions usually experience rapid and potentially stressful changes in body temperature simply because of weather changes even among amphibians there is variation in their temperature

It is believed that naturally occurring periods of temperature variation negatively impact amphibian health.
