Nerve Net
What does molting enable arthropods to do?
to grow
Asexual reproduction
requires only a single parent.
Two methods animals use to maintain homeostatic body temperature are
ectothermy and endothermy.
The thinking region of the brain is the
cerebrum
Information in the environment that causes an animal to react is
a stimulus.
Which of the following characteristics is associated only with an endoskeleton?
It grows with the animal.
Offspring produced asexually have less genetic diversity because
they have only a single parent's DNA.
An animal whose body temperature depends mostly on its relationship to sources of heat outside its body is a(n)
ectotherm
The compound eyes of insects
detect color and form images.
Highly developed nervous systems contain many
interneurons
Joints are a critical feature of both endoskeletons and exoskeletons because
joints provide flexibility and freedom of movement.
Animals, such as birds, in which embryos develop in eggs outside the parents' bodies, are considered
oviparous
Which body systems maintain homeostasis?
all of the body systems together
Which of the following invertebrates has cerebral ganglia that are organized into a brain?
octopus
Which of the following groups of animals rely on sensory cells rather than sensory tissues and organs?
tunicates
The places where parts of a skeleton are connected together to enable movement are called
joints
What is not a part of the amniotic egg

Endocrine glands regulate body activities by
releasing hormones into the blood.
The part of the vertebrate nervous system that connects the brain and the rest of the body is called the
spinal cord
If a butterfly touches sugar water with one of its legs, it usually will begin to feed. If it touches salt water, it usually will not feed. The most likely explanation for this difference in response is that butterflies
have chemical receptors for taste on their legs.
Which of the following statements describes how a muscle moves an arthropod leg?
A muscle contracts, pulling on a tendon which is attached to the inside of the exoskeleton.
External fertilization occurs when
eggs are fertilized outside the body of the egg-producing individual.
Endotherms survive more easily during cool nights or in cold weather because they
generate a lot of metabolic heat
