Question 2

A Malpighian tubule is a(n)____.

Accepted Answer

A Malpighian tubule is a type of specialized tube found in some arthropods, such as insects and spiders, that is used for waste processing and excretion. It is named after Marcello Malpighi, an Italian physician and biologist who first described the tubules in the 17th century.

Question 4

Members of the ____ subphylum are mostly insects and were among the first animals to colonize terrestrial habitats.

Accepted Answer

The subphylum Hexapoda includes insects, which were among the first animals to colonize terrestrial habitats. Myriapoda, Chelicerata, and Crustacea are all other subphyla within the phylum Arthropoda, but they do not contain as many terrestrial species as Hexapoda. Trilobita is an extinct subphylum.

Question 6

An insect whose larval and adult forms occupy different habitats and consume different food probably undergoes ____ metamorphosis.

Accepted Answer

Complete metamorphosis involves four distinct stages - egg, larva, pupa, and adult. During the larval stage, the insect looks and acts differently from the adult and occupies a different ecological niche, often consuming a different type of food. The pupal stage is a resting stage in which the insect undergoes dramatic morphological changes before emerging as an adult. Therefore, an insect that has different larval and adult habitats and food sources is likely undergoing complete metamorphosis.

Question 8

Molecular sequence analysis has revealed that Crustacea is paraphyletic, because it includes an ancestor but not all of its descendants; the descendants not included in this clade are the ____.

Accepted Answer

Hexapods, which include insects, have been shown through molecular sequence analysis to be more closely related to certain crustaceans than those crustaceans are to other members of their own group, making Crustacea paraphyletic by excluding hexapods.

Question 10

Members of the ____ subphylum, including shrimp, lobsters, and crabs, generally have five pairs of appendages on their heads: two pairs of antennae and three pairs of mouthparts, including mandibles.

Accepted Answer

The subphylum Crustacea includes shrimp, lobsters, and crabs and they generally have five pairs of appendages on their heads, including two pairs of antennae and three pairs of mouthparts, including mandibles. The other options, Myriapoda, Trilobita, Chelicerata, and Hexapoda, do not have this characteristic.

Question 13

The members of the ____ subphylum have a three-part body plan: a head, thorax, and abdomen.

Accepted Answer

The hexapoda subphylum includes insects, which have a three-part body plan consisting of a head, thorax, and abdomen. Myriapoda have many body segments but lack a distinct thorax and abdomen, Trilobita are extinct and have a body plan consisting of a cephalon, thorax, and pygidium, Chelicerata have two main body parts (prosoma and opisthosoma), and Crustacea have a two-part body plan (head and thorax fused into a cephalothorax, and abdomen).

Question 14

Members of the ____ subphylum, including spiders, ticks, mites, scorpions, and horseshoe crabs,have fanglike appendages used for biting prey and pedipalps used as grasping organs, sensory organs, or walking legs.

Accepted Answer

Chelicerata includes arachnids such as spiders, ticks, mites, scorpions, and horseshoe crabs. They are characterized by their chelicerae, which are fanglike appendages used for biting prey, and pedipalps, which are used as grasping organs, sensory organs, or walking legs. The other listed subphyla do not have these characteristics.

Question 18

Comparisons of genetic information from various invertebrate groups has ____.

Accepted Answer

Genetic comparisons have led to a reshuffling of animal classification, as genetic data often reveal relationships that differ from those suggested by phenotypic traits, and this process is ongoing.

Question 19

The organism Caenorhabditis elegans , a member of the ____ phylum, is an important model organism for studies of the genetic control of development.

Accepted Answer

Caenorhabditis elegans belongs to the Nematoda phylum, which includes roundworms. It is a well-established model organism for studying genetics and developmental biology, due to its transparent body, short life cycle, and well-mapped genome.

Question 20

Members of the ____ subphylum, including the centipedes and millipedes, have two body regions: a head with one pair of antennae and a segmented trunk with one or two pairs of legs per segment.

Accepted Answer

The description given matches that of the Myriapoda subphylum, which includes centipedes and millipedes. Trilobita, Chelicerata, Hexapoda, and Crustacea all have different body plans and characteristics.
