Regarding to the type of nutrition, all animals are:

• Autotrophic

• Heterotrophic

• Carnivores

• Herbivores

If the gas exchange takes place through the skin, that is called:

• Cutaneous respiration

• Pulmonary respiration

• Branquial respiration

• Traqueal respiration

Fish, molluscs and crustaceans have:

• Cutaneous respiration

• Pulmonary respiration

• Branquial respiration

• Traqueal respiration

If air enters the body through small openings located on the abdomen and moves into a network which carry air directly to the cells, that is:

• Cutaneous respiration

• Pulmonary respiration

• Branquial respiration

• Traqueal respiration

Terrestrial vertebrates breathe thanks to:

• Cutaneous respiration

• Pulmonary respiration

• Branquial respiration

• Traqueal respiration

The circulatory system in which the circulating fluid can move in and out of the vessels and bathes the tissues of the body is called:

• Free

• Close

• Open

• Cold

Annelids, cephalopods and vertebrates have a circulatory system which is:

• Close

• Open

• Free

• Cold

In annelids and vertebrates, the circulating fluid of the circulatory system is called:

• Hemolymph

• Hydrolymph

• Blood

In molluscs and arthropods, the circulating fluid of the circulatory system is called:

• Hemolymph

• Hydrolymph

• Blood

In echinoderms, the circulating fluid of the circulatory system is called:

• Hemolymph

• Hydrolymph

• Blood
