Which of the following is not a characteristic shared by all members of Kingdom Animalia?

motility

The largest group of animals are vertebrates.

false

During development the blastula folds inward and reorganizes into a multilayered embryo. This process is called

gastrulation

phylum whose members have a free-swimming larval stage called a trochophore

Mollusca

phylum whose name originates from the phrase “jointed foor”

Arthropoda

phylum whose members are filter feeders and can reproduce asexually by producing gemmules

Porifera

phylum whose members have a water vascular system and use tube feet to help in gas exchange

Echinoderm

phylum features a sessile,, asexually reproducing polyp and a floating sexually producing medusa

Cnidaria

Porifera use diffusion for which of the following processes?

excretion, circulation, respriation

Which of the following is not true for cnidarians?

utilize internal fertilization

All worms exhibit radial symmetry.

false

Which type of worm is an acoelomate?

flatworm

Which type of worm exhibits segmentation?

annelid

Which of the following is not a class of mollusks?

Arachnida

A hermaphrodite is an organism that:

possesses both male and female reproductive organs

All of the following are characteristics of echinoderms except:

asymmetrical

Which of the following is not a characteristic of members of the phylum Chordata?

open circulation

In chordates, the long supporting rod that runs through the body is called the

notochord

All arthropods contain 2 or 3 body segments and tend to have jointed appendages.

true

Because arthropods have exoskeletons, they have to shed their old skeleton to grow a new one in a process called:

molting

All of the following contain an open circulatory system except:

vertebrates

Which of the following is not a key characteristic of fish?

double-loop circulation

What adaptation in fish allows them to detect vibrations in water?

lateral line system

Fish have a closed circulatory system with a four chambered heart.

false

Fish have kidneys that help with the removal of waste from their body.

true

Most amphibians use external fertilization and produce soft jelly covered eggs.

true

How do amphibians and reptiles differ?

amphibians have dry skin with scales while reptiles have smooth and moist skin

Of the following, which is not a key common characteristic of all amphibians?

kidneys

All of the following are characteristics of a reptile except

have a tympanic membrane

This order of reptiles includes animals that are most closely related to birds.

Crocadylia

This adaptation best allowed reptiles to minimize water loss.

dry scaly skin

This structure of the amniotic egg encloses the embryo in a fluid-filled cavity.

amnion

Respiration in reptiles and mammals is aided by the powerful muscle called the

diaphragm

In frogs, birds and reptiles, the cavity through which feces, urine and eggs/sperm leave the body is the

cloaca

Birds are ________ because their skull has 2 temporal holes.

diaspids

A bird’s feathers are needed for

heat conservation

In most vertebrates, the amount of water in the body is controlled mainly by the

kidneys

The vertebrate group has a single loop circulatory system.

fish

Mammals have a large ________ that allows for better movement, memory and learning.

cerebrum

Each of the following is a characteristic of mammals except

ectothermic

Monotremes share characteristics with reptiles, including laying shelled eggs.

true

This group of mammals includes the koala and kangaroo.

marsupials
