1) We know that snakes are animals of the order Squamata. About these animals, mark the correct alternative.
a) All snakes are venomous.
b) The presence of pelvic bones and vestigial limbs in some species demonstrates their ancestry.
c) The lack of limbs makes movement difficult, so snakes are only found on the ground.
d) All snakes are more than two meters long.
e) Snakes have little sharp senses and are only able to capture their prey when there is physical contact between them.
2) Of the reptiles mentioned below, which is a representative of the order Squamata?
the turtle.
b) Lizard.
c) Tortoise.
d) Crocodile.
e) Alligator.
3) What are the suborders of the Squamata group?
a) Lacertilia or Saurios; Amphisbaenids and Ophidians.
b) Sternorrhyncha, Auchenorrhyncha, Heteroptera.
c) Megachiroptera and Microchiroptera.
d) Opisthothelae and Araneomorphae.
4) About the order Squamata, mark the incorrect alternative.
a) Amphisbaenians are representatives of the order Squamata.
b) The order Squamata has representatives that have a body covered with scales.
c) Representatives of the order Squamata are endothermic.
d) The squamates do not have representatives in Antarctica.
e) We can divide the squamates into two large groups, Iguania and Scleroglossa.
5) Snakes are animals of the order Squamata and the group:
a) Iguania.
b) Scleroglossa.
c) Testudines.
d) Pleurodonta.
e) Acrodont.
6) (UFT) The transition of living beings from water to land took millions of years to happen. During this period, a series of changes gradually adjusted the structural plan of organisms, allowing the resolution of problems of adaptation to the terrestrial environment. The terrestrial environment offers advantages such as greater availability of oxygen and exposure to solar radiation. On the other hand, low water availability increases the risk of dehydration and imposes restrictions on species reproduction.
Among the events that allowed the successful transition of living beings from the aquatic to the terrestrial environment, analyze those mentioned below.
I – The emergence of the amniotic egg.
II – The appearance of the pollen tube.
III – The presence of a kidney that excretes ammonia.
IV – The presence of dry and keratinized skin.
Which of the above statements are true:
a) I, II, III and IV.
b) I, III and IV.
c) I, II and IV.
d) I, II and III.
e) none of the above alternatives.
7) Regarding the Reptilia Class, mark with (T) for true or (F) for false:
a) ( ) most reptiles excrete uric acid: less toxic than ammonia and quite soluble in water.
b) ( ) Jacobson's organ is found in venomous snakes.
c) ( ) the presence of muscles around the ribs of reptiles facilitates lung ventilation.
d) ( ) two-headed snakes are not snakes, nor are legless lizards.
e) ( ) the eggs of reptiles have amnion, yolk sac, allantois and chorion.
8) Regarding the classification of Reptiles, complete the sentences using the words listed below.
Squamata – Chelonia – Crocodilia – Rhyncocephalia
a) The Order _____________ gathers animals endemic to New Zealand: the tuataras.
b) The Order _____________ gathers, among other animals, gharials and alligators.
c) The Order _____________ includes both aquatic and terrestrial species.
d) The Order _____________ gathers lizards, serpents and blind snakes.
9) Some lizards have the ability to autotomy to protect themselves from predators. About this capacity, mark the correct one.
a) Autotomy allows lizards to change color to camouflage themselves.
b) This ability allows the lizard to run faster to escape predators.
c) Autotomy allows the lizard to spontaneously lose its tail when it feels threatened by a predator.
d) With autotomy the animal can change its body temperature.
10) (UEMS) Considering the evolutionary aspects of reptiles and the main characteristics presented by them, which enabled a better adaptation to the terrestrial environment, it can be said that feature:
a) endothermy and closed blood circulation.
b) internal fertilization with small eggs without yolk and endothermy.
c) breathing through lungs, porous bone structure, with less dense bones than other vertebrates.
d) eggs with shell adapted for the terrestrial environment, cornified skin more resistant to abrasion and water loss.
e) ectothermia and cutaneous respiration.
