considered pests.

Explain three ways in which God designed insects to play a positive role the world.
They pollinate flowering plants;
they scavenge, which helps decompose dead organisms and waste;
they till and aerate the soil;
they are food for many other species;
and they produce products such as honey and silk for human use.
A millipede has two pairs of legs on every body segment behind its head.
True
Ectotherms need more food energy than endotherms.
False. Endotherms need more energy to keep their bodies warm because they regulate their own body temperature.

a a bird. c a fish.

Answers will vary but should include their features, habitats, food, and methods of reproduction.
Most crustaceans live in the ocean.
True
All cnidarians are harmless sea creatures.
Hydras are one of the few polyp-shaped cnidarians that can move around on their own.

a sight. c hearing.

Explain the difference between endotherms and ectotherms and give an example of each.
Endotherms can internally regulate their body temperatures by burning the calories that they consume. Birds and mammals are endotherms.
Ectotherms cannot internally regulate their body temperatures; they must draw heat from their environment. Reptiles, fish, and amphibians are ectotherms.
Arthropods are distinguishable from other invertebrates in all of the following ways, except that
a arthropods have jointed legs.
b arthropods have a segmented body.
c arthropods have no backbone.
d arthropods have an exoskeleton.
C No backbone
Most insects have two types of eyes: simple and compound
Individual coral organisms can grow to enormous sizes.
True
False. Each coral polyp is only a few millimeters long. The reefs grow as successive generations of polyps add their limestone covering to the structure.
A planarian is a type of
a flatworm. c roundworm.
b segmented worm. d cnidarian.
Sea urchins, sand dollars, and starfish all have
a gills. c tube feet.
b compound eyes. d antennae.
A Flatworm
C Tube feet
Describe the unique features of an amphibian’s skin. How is that type of skin an advantage and a disadvantage for them?
Amphibians have moist, scaleless skin that secretes mucus and sometimes poison. It is permeable to gases and water, so amphibians can breathe through their skins.
advantage: Breathing occurs through skin. disadvantage: Skin-breathing makes amphibians susceptible to air and water pollution.
The basic characteristics of all vertebrates include all of the following, except
A. the ability to internally regulate their body temperature.
B. a brain protected by a cranium.
C. an endoskeleton.
D. a closed circulatory system.
