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.
The horned marsupial frog, is a species of frog in the family Hemiphractidae. It is an arboreal species found in Colombia, Costa Rica, Ecuador and Panama.

Answer: 40 mm Hg, 95 mm Hg, out of, down
Explanation:
In tissue cells the P(O2) is 40 mm Hg. The blood as it reaches the systemic capillaries around it has a P(O2) of 95 mm Hg. Hence, oxygen diffuses into the cells from the systemic capillaries down the partial pressure gradient. The carbon dioxide diffuses in the same direction at the same time.
Hence, the blanks will be filled with 40 mm Hg, 95 mm Hg, out of, down.
