Reptiles were very successful on land while amphibians were not. What evolutionary development was primarily responsible for the success of reptiles on land?
1. Scales over skin
2. Thoracic breathing
3. Amniotic egg
4. Strong Jaws
Which of the following is not a feature of Tunicates?
| 1. | Only the larvae have notochord |
| 2. | Presence of endostyle |
| 3. | Secretion of cellulose sac |
| 4. | Larvae are voracious eaters |
Consider the following sets of some animals. The set that consists of all animals belonging to the same phylum is:
1. Pinctada, Aplysia, Chaetopleura
2. Dentallium, Pila, Echinus
3. Asterias, Antedon, Ascidia
4. Adamsia, Gorgonia, Pleurobrachia
Identify the option where all the columns are not correctly matched:
| Animal | Phylum | Features | |
| 1. | Pleurobrachia | Ctenophora | Comb plates, Only sexual reproduction |
| 2. | Loligo | Mollusca | Radula, Dioecious |
| 3. | Balanoglossus | Hemichordata | Respiration by gills, excretion by Proboscis gland |
| 4. | Ascidia | Chordata | Marine, Notochord persistent throughout life |
Which of the following is not an Echinoderm character?
| 1. | Exclusively marine |
| 2. | Radial symmetry in adults |
| 3. | Protostome embryonic development |
| 4. | Water vascular system |
Birds are not characterized by:
1. Forelimbs modified into wings
2. Fully ossified endoskeleton
3. Skin dry without glands except for oil gland
4. Oviparous and external fertilization
Echinoderms are not characterized by:
| 1. | An absence of excretory system |
| 2. | Bisexual animals |
| 3. | Usually external fertilization |
| 4. | Indirect development with free swimming larva |
Identify the incorrectly matched pair:
| Animals | Feature present in both | |
| 1. | Balanoglossus and Pinctada | Open circulatory system |
| 2. | Branchiostoma and Ascidia | Persistent notochord |
| 3. | Aplysia and Pheretima | True coelom |
| 4. | Gorgonia and Pennatula | Cnidoblasts |
Pteropus is a/an:
| 1. | Limbless amphibian |
| 2. | Extinct reptile that evolved into mammals |
| 3. | Bony fish that migrates from sea water to fresh water for breeding |
| 4. | Mammal with flight |
