19.

Metamorphosis often results in adult and immature stages having different feeding habits and habitats. Metamorphosis, therefore, reduces competition between adult and immature stages and has contributed to the success of the arthropods.
A)True
B)False
20.

Metamerism has arisen at least three times in animal evolution.
A)True
B)False
21.

Krill are in the class Branchiopoda.
A)True
B)False
22.

Arthropods that have just undergone ecdysis are secretive and remain hidden because the new exoskeleton has not yet hardened.
A)True
B)False
23.

Book lungs or book gills are present in members of the subphylum Crustacea.
A)True
B)False
24.

Scorpions have a period of courtship prior to mating. Mating occurs by copulation and the direct transfer of sperm from the male to the female.
A)True
B)False
25.

Members of the class Pycnogonida are the sea spiders. Pycnogonids are dioecious. After eggs are fertilized, they are cemented onto ovigers of the male where they are carried until hatching.
A)True
B)False
26.

The appendages of a crayfish are said to be serially homologous because they have evolved from a common ancestral form. The common ancestral form is the biramous appendage, which consists of a protopodite that attaches to the body wall and gives rise to two distal processes.

B)False
27.

In the barnacles, planktonic nauplius larvae attach to the substrate by their first antennae and metamorphose to adults.
A)True
B)False
28.

Members of the subphylum Chelicerata were preadapted for terrestrial life by the exoskeleton, which was relatively impermeable to water and supportive on land. Members of the class Arachnida were some of the very early terrestrial inhabitants.

30.
